Hello, welcome to a crossover between Kamen Rider and Senran Kagura.

After reading The tale of the legendary super ninja by KamenRiderNexus98 and Senran Kagura: The Multi-King by Shunya Toshiki, I became so inspired that I decided to write my own Kamen Rider x Senran Kagura/閃乱カグラ Crossover.

That and because of the way KamenRiderNexus98 wrote his story, which made me cringe(Not trying to offend anyone here). I'm not a master writer either.

So I just want to try writing something with good grammar and spelling. And this story is more or less a practice of sorts for my English writing skills.

The main Kamen Rider of this story will be Kamen Rider Shinobi(Obviously).

I also began to watch the Kamen Rider Zi-O Spin-off: Rider Time: Kamen Rider Shinobi to get some ideas for how Shinobi's fighting style and powers would more or less work.

That said, I do intend to perhaps put other Kamen Riders, like Kamen Rider Hattari, in this story later.

This is another new project that is still in development and maybe would take a while to be properly updated later. But I eventually hope you guys enjoy it.

Now, onto the story.

"Speaking"

'Thinking'

[Shinobi Driver]

Shinobi

In the past, these agents served under daimyos and other feudal lords. They worked as professional spies, assassins and saboteurs.

This tale is about modern-day shinobi and their fight against evil.

However, this is not only about the tale of five young girls...

This is also the story of a young warrior as he fights to regain what he once lost while walking the path towards his quest for justice and the pursuit of the truth...

At an abandoned factory area - Nighttime

[Ninpo Kirisute!]

A dark figure, armed with a Ninjatō, proceeds to slash an individual garbed in dark ninja clothes.

The 'dark ninja' is one of the Hoshikuzu Ninja Dustards, black-robed ninja foot soldiers that serve a dark organization of evil, the Serpent Society.

"Argh!" The ninja cried in pain as he was sent to crash against a nearby wall, leaving some cracks on it. He eventually gets knocked out.

"Kisama! Who the hell are you!? How dare you get in our way!? The Serpent Society!" Another Dustard, identical in everything to the first one, said angrily as he and many more like him appeared beside their fallen comrade.

The ninjas all draw some short swords and proceed to attack their single enemy.

At this, the dark figure quickly made some acrobatic moves, avoiding the katanas from several of them, and lands on top of a pillar. He looks down at all of them as he crosses his arms.

"Serpent Society! Whenever you evil ninjas chose to run rampant, I will always appear to ruin your plans! Be aware! As my name is.. Shinobi!" The shadowy figure declared.

The moonlight casts down on the figure, finally revealing his true form under its rays.

The mysterious warrior is clad in purple and black armor, wearing a suit with ninja, shurikens, kunais, stickers and frog motifs.

His helmet is purple with a ninja shuriken in the front. It also has yellow 'eyes' and a smaller shuriken symbol on its forehead. His torso is black and purple with a shuriken on the chest. A black armor is present on his arms and legs with purple bands wrapping on the forearms and forelegs. In addition, he has a purple scarf around his neck.

Around his waist is a black belt with a purple ninja star attached to it, also serving as its 'buckle'. This item was the Shinobi Driver, a powerful item that allowed this warrior to adorn his current armor.

This person is Kamen Rider Shinobi:

The warrior from the shadows that protect the weak from those who abuse their powers.

"Time to end this!" Shinobi declares as he prepares to execute his finisher. He begins to make a series of hand gestures as energy starts to be stored inside his soul.

Next, Kamen Rider Shinobi then spins the shuriken in his belt and covers himself in a purple aura, now properly ready to deal the finishing blow against his enemies.

[Finish Ninpo!]

As his Shinobi Driver announced, the ninja Rider jumps in the sky. The full moon is behind him, with its rays shining upon his figure.

"Ha! Ninpo: Rider Kick no Jutsu!" Shinobi yelled as he made a flying kick towards the group of Dustards, making them earn frightened expressions.

His special kick successfully hits his targets, the black-robed ninjas, causing all of them to eventually explode.

"Ahhh!" The Dustards all screamed in pain.

*Boom!* *Boom!* *Boom!*

The ninja warrior lands on one knee and slowly got up while twirling his purple scarf to the air. All done with only his back facing the explosion as he didn't turn around to look at it himself.

[Victory Ninjutsu!] The Shinobi Driver announced.

A Kamen Rider Shinobi x Senran Kagura crossover:

Senran Kagura: Shinobi Chronicles

Ninpo 1: My name is Shinobi!

? - Unknown Location...

A six years old child wearing a brown jacket with a green shirt was standing on a plain field. He also wore blue pants, brown boots. He had short spiky black hair and gray eyes.

He looked emotionless while holding a shuriken in his right hand and a kunai in his left one, gazing at the horizon in front of him as the wind began to blow gently around the area.

"Hey, you... Wake up." A gentle voice called.

Asakusa - Daytime- Inside a ship that is heading towards the city

"*Yawn~*"

The boy finally wakes up from his dream, opening his gray eyes. Now revealed to actually be a 16 years old young man that was taking a nap.

He was leaning against a wall and finally decides to walk around and inspect his surroundings.

'Well, here I am, back to Asakusa. It's been a while since I left...' He calmly thought.

He was currently wearing a dark blue jacket, a black shirt underneath it, a pair of light blue jeans and green sneakers. There was also a silver bottle gourd tied to a black belt he was wearing around his waist. He was also carrying a black bag around his shoulder.

And just like when he was six years old, he has black hair and gray eyes.

His name is Kamui Yukio. Kamen Rider Shinobi's real identity. A boy who, secretly, is also a skilled ninja that poses as an ordinary high school teenager.

He recently transferred to Hanzo Academy, in Asakusa, now planning to be living in its dormitory-like some of its students for a while. All while continuing his quest.

He is currently waiting patiently on a ship that is heading towards Asakusa's port.

'After all this time… I finally found a way to finally fight against the Serpent Society on higher ground. With this… I can perhaps finally destroy them and uncover everything...' He thinks as he briefly looks at his right hand for a moment and clenches it, soon adopting a serious expression on his face.

He then leans against the railing of the ship he is traveling and enters in deep thought as he plans what to do next. He turns around and decides to stare at the water until he suddenly gets distracted by a girl's voice.

"Oh wow, I can't believe I'm finally home. The city looks even prettier than the last time I remember."

Hmm?

Yukio decides to look behind to see who it was.

It was a brunette girl wearing the Hanzo Academy's female uniform, which consisted of a white shirt, a blue tie and a dark blue skirt.

If Yukio heard it right, she said she was back home. This meant that it was a chance for him to get some info of the city and of the Hanzo Academy, as a bonus.

'She must be from here. Might as well ask her about this city.' He thought.

He was going to approach her but Scarf Girl was intercepted by a tanned girl with a ponytail in a black sailor uniform.

As Yukio observed, she is a young woman with tanned skin that has long black hair that is kept tied by a white ribbon and that goes past her thighs.

She wears a black and red school uniform with a shirt that exposes a sizeable amount of her midriff, a very short miniskirt that doesn't do much to cover her buttocks, revealing a plentiful portion of her buttcheeks, especially with a gust of wind or the slightest forward movement. She also wears thick knee-high schoolgirl socks.

"So, you're from here, huh? Since you said you're back home, I'm guessing you're from here." Scarf girl turns her head towards the black uniform girl as she asks:

"Was I that loud?"

"Well I don't think the whole boat heard you, but I definitely did. And so does the boy behind us." The ponytail girl replies with a smirk on her face while pointing with her thumb towards Yukio.

Yukio simply waves awkwardly at them with a stoic expression, making both girls sweatdrop at him.

Ignoring him, the Scarf Girl turns to look at the black uniform girl with an embarrassed look on her face.

"A-Ah I'm so sorry! It's just that I was going to school and I loved it. But something happened, and I have to leave for a bit… I'm sorry, I'll shut up now," she said as she lowers her head. She chuckled a bit as she babbled to explain something to the tanned girl.

The tanned girl simply chuckles at that and turns around, before walking away.

"Well, you're an interesting one." She said as she walked away.

"I am?" Scarf girl asks back, without receiving a response to that.

The tanned girl simply waved goodbye to her after that as the ship was finally about to board at the local dock.

Remembering what he wanted to ask, Yukio calmly approaches Scarf Girl before could she leave.

"Excuse me, but could you help me with something? You must be going to the Hanzo Academy, right? I assumed that by judging the uniform you're wearing." He said politely while pointing at her current outfit.

The scarf girl replies, surprised:

"That's right! How'd you know?"

"It's because I'm transferring there and I'm starting my classes tomorrow. Since you're a student, I was wondering if you could show me the way to the school and where its dormitory is? That is if it's not a problem for you." Yukio asks politely to her.

"Sure, no problem at all. I'll be happy to help you. I'm Asuka by the way," she said with a smile on her face.

"I'm Kamui. Kamui Yukio." Yukio said as he extends a hand to Asuka, which she gladly accepts.

Later...

Hanzō National Academy

A famous prep school which, having been founded in 1919, is nearing its 100th anniversary. One thousand students are currently enrolled there.

However, mixed in with the ordinary students are a small number of students in the shinobi training course: youngsters training to become future professional ninjas.

The academy was originally founded as a normal high school. But when the shinobi course began, it changed its name to "Hanzo". It was named after a certain legendary shinobi.

The only people who know of the shinobi course's existence other than its instructor, a man called Kiriya, are the principal and vice principal of this institution.

In addition to shinobi classes, instructor Kiriya also happens to teach ordinary math classes to normal students.

To the Shinobi World, this place is a very well know ninja school.

And so, Asuka guides Yukio to the Hanzo Academy.

She gives him a quick tour around the school, eventually showing him the boys' dormitory.

"Well, that's all that I can show you," Asuka says as she then points to the main doors of the school.

"The faculty office is in the main building to the left. I believe you will find it easily there. I'm sure you won't miss it at all." She explains.

"Got it. Thank you for the time you spared, showing around the school for me, Asuka-san." Yukio says as he thanks Asuka and gives her a nod.

"You're welcome." She said, giving a smile to him.

As Yukio sees the dormitory one more time, Asuka turns to see the clock on the main building of the academy. Her eyes soon widen at the time.

Yukio turned around to say goodbye to her, but she just disappeared. He was surprised for one second but concluded that she had her reasons. He shrugged and began to walk towards his dormitory.

"Alright… Well, my stuff should have been transferred to my dorm room by now. Might as well go there and unpack everything. I guess Asuka-san had more important things to do now. But I wonder... Is she some sort of ninja?" Yukio spoke aloud as he heads to his dormitory.

He then stops for a moment and glares at the upper part of a random tree, before stopping and shrugging again, eventually resuming his walk.

Unaware to him, Asuka was above him on a nearby tree branch of the said tree he was looking at and heard everything he just said, as well as looking at him from there.

'D-Did he actually knew I was here!? And h-he actually thinks that I'm a ninja!? No, wait! That can't be! He must be joking, right!? Anyway, I can't be late for training!' She thought surprised as she quickly disappeared and left the area.

Hanzo Academy - Old Building

As said before, unbeknownst to the students and most of the school's staff, the Academy is also known to be a Shinobi Academy where certain individuals come here in order to train. All while aiming to be a full-pledged Shinobi.

Asuka, one of these said individuals, snuck herself into a traditional tea room where it has a back door that leads to another hidden room where Shinobis meet and train.

She opens the door and went in.

As she enters the classroom, a Japanese style room, she quickly finds a student having tea at the table there.

A refined girl with long straight black hair and flat- cut bangs. This is Ikaruga.

"Oh, I made it just in time. *Sigh*" Asuka said, sighing in relief.

"Welcome back, Asuka." Ikaruga greets Asuka.

"Thanks, Ikaruga-san. I'm pumped and ready to get back to training." Asuka said as she bows.

"I'm glad you manage to give that boy the slip earlier," Ikaruga stated.

Asuka was a little surprised by that.

"You have been watching?" The brunette asks in embarrassment.

Ikaruga then turns her head towards Asuka as she answers:

"Of course, I did, you didn't conceal your presence. You should know better than give some random boy a tour around the school." At this, Asuka begins to rub the back of her head sheepishly.

"Guess I'm excited because I have been away for so long." Asuka tried to justify herself.

"While we're technically students here, our identities must remain secret. Please be careful next time and don't blow our cover." Ikaruga stated to her.

"Sumimasen. It won't happen again, Ikaruga-san." Asuka said, apologizing.

Suddenly, a pair of hands grab Asuka from behind and starts fondling around with her boobs.

They belonged to another ninja student, a blond-haired girl that wears a blue headband with laces on the left and right side of her head. To her friends, she is mainly known for her spunky attitude. This is Katsuragi.

"Did you get in trouble? This is not like you, Asuka." She said with a grin while still fondling with Asuka's boobs.

Asuka was surprised as she keeps getting more and more embarrassed with her perverted friend shenanigans.

"Let go, Katsu-nee!" Asuka yells.

"Oh, how I miss your bodacious curves!" Katsuragi exclaims.

Asuka manages to get out of her hold and stepped back.

"Why do you insist on fondling with mine when you got your own!?" Asuka exclaimed as she points at the blond's chest.

Katsuragi simply laughs at her statement and makes some gestures with her hands as she responded:

"A little groping didn't hurt anybody. It might even help you grow a cup size or two." Asuka covers her chest in embarrassment at this.

"I don't want them bigger! In fact, I prefer would prefer them smaller!" The brunette yelled.

"Would you really trade those big ones for small ones?" Katsuragi asks, teasing Asuka.

"Yeah! In a heartbeat!" Asuka exclaims to her.

*Thud!*

They heard a loud noise from the hidden door and turn around to see who it was.

A pink-haired girl in small Pigtails was currently on the ground with splattered snacks on the floor. This adorable girl is Hibari.

"Ow! That really hurt!" The pinkette spoke while rubbing her ass in pain. She then sighs at this.

"You ought to be the clumsiest person I've ever met, Hibari". Katsuragi scolded her.

Hibari then looks up to see her friends.

"I thought I was going be late so I came here in a hurry. But then, I got stuck on the secret door and dropped all of my candy. Oh! When did you get back, Asuka-chan?" Hibari said with a happy expression, finally noticing that her friend was back.

"This morning, I just arrived now," Asuka replied to Hibari.

"How'd you do? Did you pass your promotion test?" Hibari, happy at this, asks her curiously.

"Yep! Yeah, I did," Asuka answers her.

"That's great to hear. I'm so happy for you!" Hibari congratulates Asuka.

"Thanks. I'm just glad it's over." Asuka said back to her clumsy friend.

"Hibari. Before you congratulate others, you should first make some progress yourself." A new voice said to Hibari.

It came from a nearby window from a white-haired student with long twin-tails held with shuriken. She has red eyes and wears a patch over the one; however, the eye it covers is functional.

She was currently eating some dry squid. This is the prodigy ninja, Yagyu. She is normally depicted with an indifferent expression.

"That's all right. I didn't pull it off myself, but I'm still happy about it." Hibari replied with a smile to Yagyu.

"Yagyu-chan, when did you get here? Where did you come from? I didn't see you there." Asuka was surprised by her sudden arrival.

"That's because I was concealing my presence from you. It's a basic shinobi skill." Yagyu answers her.

"Hehehe… Right..." Asuka laughs sheepishly at the response.

"Jeez. You are not gonna let an underclassman get the best of you, are you?" Katsuragi asked Asuka with a grin.

"Yagyu-chan has a higher rank despite being a freshman, though," Asuka replies back.

"That's because Yagyu-chan's a Shinobi prodigy," Hibari exclaimed to them.

*Boom!*

Suddenly, a smoke bomb blows up in the classroom. When it cleared out, a man is now standing there. This is the girls' Shinobi teacher, Kiriya.

Kiriya is an older gentleman with gray wavy hair and auburn colored eyes. He is often seen in a black suit and various other formal attires.

"Everyone's here, correct? It's time to begin class, ladies." He calmly spoke to the five.

The students all bowed to their teacher.

"Good morning, Kiriya sensei." Ikaruga greets him.

Kiriya nods to her and then turns his head to Asuka.

"Asuka." He calls the brunette.

"H-Hai!?" Asuka replies back.

"I heard you passed your test. Good work." Kiriya praises her.

"Oh, thanks for the praise." Asuka timidly answered back.

Kiriya then opens his book to see her score.

"Let's see your scores. Hmm… Used an empty-shell when the scroll was about to be taken, and in the process, damaged your shinobi outfit… You used smoke bombs in an urban area… Time was nearly zero...

Oh! This is impressive: Your score perfectly matches the passing mark. That's not something one can do on purpose." Kirya spoke while smirking at her scores, sounding a little amused at her performance.

Asuka was embarrassed by this and exclaims:

"Don't get excited about silly things! Let's focus on the good! At least I passed, right?"

Kiriya closed his book and said to Asuka:

"True. I've never said you had to ace it. well, you passed, and that's what counts. But I want you to earn a higher grade next time. Continue to train hard."

"Hai!" Asuka replies back.

"We'll spend today's first-period practicing hand-to-hand combat. Everyone, get changed and gather in the training hall." Kiriya told to the girls.

And so another day begins at the Hanzo Shinobi School as these five girls prepare themselves and start training to become future ninjas.

'I vow to make you all into fine shinobi. And eventually… You all will have to battle against the evil shinobis and all other dangers that threaten the peace of the world. Like the Youmas… And the Serpent Society. I just hope you girls don't run into any of them until you graduate.' Kiriya thought with a deep frown while looking at the enthusiastic girls.

Hanzo Academy - Boys' Dormitory - Yukio's Room

Yukio was at his dorm room, finally finishing unpacking everything he had.

He was now wearing the male version of Hanzo Academy's uniform: A white short-sleeved Shirt, a blue tie, dark blue pants, and his green sneakers.

His room was a simple small one filled with a study desk, a one-person bed, a kitchen, and a bathroom. There was also a bookshelf that seemed to be filled with some important books, texts, and documents next to a window.

'Alright, I've finally finished unpacking all my stuff. Now then…' Yukio thought as he inspects his room, confirming that everything was finally set.

With that done, he picks his purple smartphone and calls someone.

"Moshi-moshi? Hanamura-san? It's me. I'm finally back from my expedition. I just finished enrolling myself at Hanzo Academy. Where are you right now? At Asakusa's shopping district? Okay, I will meet you there."

*Beep*

With this, Yukio turns off his phone and prepares to leave his room.

He soon gets out of his room, locking it and begins to head towards Asakusa's shopping district.

? - Unknown Location - The Serpent Society's hideout

A dark space, completely covered in shadows with not even a single ray of light present around the area.

In the center of this area, a menacing figure stood, alone.

He was wearing what could be described as a black version to an armor similar to the one used by the 2003's Teenage Mutant Ninja Turtles Utrom Shredder.

He is a slim, but tall, muscular, and toned man with shiny, chrome plate armor on his chest, shoulders, arms and lower legs. He was using a silver samurai helmet that only showed glowing red eyes, covering the rest of his face.

There was also a tekko-kagi attached to his right hand and green snake symbols on his chest and helmet.

This individual was known as Orochi, the leader and head of the Serpent Society.

The Serpent Society was a clan fully composed of evil ninjas that planned to rule over the entire world using their unique ninjutsu, modern technology and some special powers known only to them. They also destroyed everyone that tried to get in their way. It didn't matter if the individual was also a good or evil shinobi.

They remained in the shadows for a good time, with most unaware of them. Until now…

"Hahaha… After all these years… I'm finally close. Once I obtain the legendary Twilight Scroll, nobody will be able to stand against the Serpent Society and we will finally conquer this world! And rightfully rule it as its new kings." Orochi said while chuckling darkly.

At this, a puff of smoke suddenly formed behind of and a new figure now stood behind the evil leader.

Said individual was wearing black armor with many crow feathers gathered around his arms and legs. He also used a crow-shaped helmet. This was one of Orochi's loyal followers, a shinobi called Karasu.

"Orochi-sama. Our men have finished inspecting the ruins of the lost temple. However, there were no signals of the Twilight Ninja Art Scroll there. We assume that somebody already must have taken it before us." Karasu announced as he got on one knee and bowed to his leader.

"What!? If that's true then our efforts will all have been for naught. Find the scroll no matter what. Do not fail me, Karasu!" Orochi growled.

"Yes, my lord. And there is one other concern. An individual by the name of Shinobi has been hindering all of our efforts so far."

"Huh? An agent of the good ninjas, perhaps? No… Knowing them, it would have been more obvious if that was really the case." Orochi muttered as he slowly digested the information.

"So far, he has skillfully blocked our tracking methods and easily erased all of his activities against us. Whoever he is, it seems to be quite an adept ninja." Karasu explained.

"That is quite interesting, but leave that alone for now. Searching for the Twilight Scroll is our main priority. Once it's in my hands, I will be able to finally control this world." Orochi ordered, making Karasu leave the area.

Asakusa's Shopping District

The local was full of life as many people walked around the area that was filled with several sorts of business, services, and stores available for the public.

At one area of the district was a blue food truck, serving several sorts of food to anyone interested. There was a sign next to it saying 'Café Hana: Coffee - Drink - Snacks' featuring a smiling cat eating some dango.

The vehicle is equipped with a kitchen, several storage shelves, a coffee machine.

And next to the food truck was Yukio, who seemed to be calmly eating some dango. He was sitting on a metal recliner chair while looking at the sky.

"So, how was your trip?" Asked a man behind the counter of the food truck. He also happens to be the owner.

He is a 24 years old young man with fair skin and brown eyes. His dark brown hair comes to the base of his neck, and it has multiple small bangs brushed over to hide his forehead. He also sports a small goatee.

This is Hanamura Junpei, a close friend of Yukio who is also aware of his activities as a ninja and of his alter ego Kamen Rider Shinobi.

Junpei dresses simply, wearing a brown trench coat over a purple hoodie with a bronze zipper and light blue shirt, and teal pants tucked into burgundy boots with prominent black soles.

"I guess it went well in the end, despite some of the challenges that appeared along the way, Hanamura-san." Yukio replied, finally finishing his dango and throwing the stick away at a nearby trash can.

"I see… So, you decided to enroll in Hanzo Academy, right? I hope you enjoy your new school here. Maybe… You could finally find something to enjoy your life and maybe even make some new friends here to have fun with." Junpei said, trying to cheer Yukio up.

"I… I don't think I have time for something like this, Hanamura-san. I just enrolled there because of how convenient it would be… For our next actions." Yukio spoke, not sure of how to feel about his current situation.

At this, Junpei sighed a bit and began to cook some more dango to sell, adopting a disheartened expression after hearing Yukio's answer.

"I feel bad that I got you involved in this, Yukio." The brunette replied to the teen.

"No, you don't need to feel responsible. I'm doing this of my own free will. I promise to get revenge on those who took your younger brother's and my past away. I choose to fight to stop the Serpent Society and to regain what I lost. That's why I also decided to become a shinobi." Yukio said, fully determined, while still looking towards the sky.

"Yukio..." Junpei muttered.

The Rider then gets up from his chair and approaches the counter.

"Anyway, have there been any changes? Anything important about the good or evil ninjas? Or the Serpent Society?" The teen asked the older man.

Junpei also happened to be working together with Yukio, helping the teen collect important and relevant information about the Shinobi World that could help them later in their quest against the Serpent Society and other people that threaten the peace of the world.

"No, nothing. But I have acquired intel regarding some good and evil ninja in training you should be aware of. They all also happen to be girls around your age group. One of them also happens to be the granddaughter of Hanzo, the legendary shinobi." Junpei spoke as he grabs a folder and hands it to the ravenette.

"You should also know that there is a shinobi academy inside of your new school. Be careful or they might find out about you eventually. A teacher from the Academy named Kiriya is the instructor there." Junpei warned Yukio, receiving back a nod from the teenager.

The Rider reads all the information he acquired and confirmed his suspicions about Asuka being a shinobi, also learning that she is Hanzo's granddaughter.

He learns about her backstory and also a bit about her four friends: Ikaruga, Katsuragi, Hibari and Yagyu.

He gets slightly surprised when he learned that the girl in the black sailor uniform he saw earlier at the ship was actually an evil ninja.

She was Homura, an elite student of the Hebijo Clandestine Girls Academy.

The Hebijo Clandestine Girls' Academy, is a ninja school affiliated with evil ninja. It is considered the rival school of the Hanzō Academy.

A vocational school for evil shinobi whose creed is, 'Where good accepts few, evil accepts all.' It was originally founded as an ordinary private school, but after a certain incident three years ago, it was re-established as a hidden school.

The school's management is made up of leaders from large corporations, so many of the evil shinobi who graduate from the academy end up working to increase those corporations' profits. The training is harsh, and it's not unusual for students to die, but Hebijo's reputation for excellence draws a never-ending stream of applicants.

Yukio then proceeds to learn some info regarding some of the Homura's companions: Four girls called Yomi, Hikage, Mirai and Haruka.

"As expected, your information gathering skills are excellent as always, Hanamura-san. Thanks to this, I'm now aware of all them." Yukio said as he finished analyzing all the information given to him.

"Good to know. So, what do you wanted to talk to me?" The brunette asked.

In response, Yukio suddenly pulls out a platinum-colored scroll from one of his pants' pockets.

"*Gasp!* That's-!" Junpei spoke, unable to contain his shock.

"Yes. That's the rumored legendary Twilight Ninja Art Scroll. An ancient relic that holds many sorts of mysterious powers in it." Yukio explained.

The Twilight Scroll was a rumored fairytale-like item. An artifact that many in the Shinobi World would desire to have in their hands. On the wrong hands, it is said to be capable of possibly destroying the entire world.

"No way… It's actually real… Masaka… So on your last trip..." Junpei exclaimed as the realization hit him.

"That's right. I found out about the existence of an ancient temple that could be guarding something very valuable. If it wasn't for my Shinobi Driver, I might not even have returned from there alive.

The place was heavily guarded and I think even the most experienced ninjas would have trouble there. But I somehow managed to explore it in the end. Imagine my surprise when I found this." Yukio explained while gesturing at the ancient scroll.

"Have you tried to open it?" Junpei asked, curious.

"No. Not yet. It seems that there's a special seal in it that the moment I remove it, every single shinobi in the world will quickly become aware of the scroll's existence." The teen explained, making Junpei's eye widen at this.

"I see… If that happens… Not only the Serpent Society, but groups of good and evil ninja will also come after you to try to obtain the scroll and its secrets from your hands." Junpei deduced, receiving a nod from his younger companion.

"Yeah. However… This could also be the trump card we need to finally destroy the Serpents once and for all. I'm still planning to open it regardless, Hanamura-san." Yukio explained, adopting a serious expression.

"Yukio… I see. Then let's head to the inside of my food truck. The moment you open it… There's no turning back for the both of us." Junpei said.

The two then quickly head to the inside of the vehicle, closing the mobile café from the public's view.

A while later...

With Asuka and her friends…

The brunette shinobi and her friends came to Asakusa's shopping district in a 'mission' to get rid of some local delinquents that were causing trouble for the local folks there.

Apparently, that was not all of it as the troublemakers were actually dolls disguised as humans. Someone might have been actually wanting to test these girls abilities.

A Shinobi Barrier was even created, making some of the girls, like Ikaruga, a bit wary of the situation.

A Shinobi Barrier, sometimes called Camouflage Barrier, is a battlespace created by shinobi to keep out civilians. It has a limited range and is mostly used for duels.

When a shinobi enters combat, it blockades off a space of a fixed size, impenetrable to the average person. It's useful for covert activities, but there is a downside. Since shinobi can sense its activation, it can give away a shinobi's position.

Shinobi with enough power can create this special type of barrier. Since those of particularly great will power can enter the barrier, it is commonly used to keep civilians out of a fight, as well as detecting the presence of other shinobi or people wielding power. In the event that one should find oneself trapped within a barrier, eliminating all enemies in the area will dispel it.

Ikaruga scolded Asuka since she didn't appear in time to help her teammates deal with the mysterious living mannequins in the Shinobi Barrier.

Currently, the girls were heading back to Hanzo Academy when suddenly…

*Boom!* *Boom!* *Crash!* *Crash!*

Several Dustards suddenly began to appear around the district, causing destruction and attacking every single civilian nearby.

"Ahhh!" People began to flee from the area in panic and fear.

Leading all of these black ninjas was what appeared to be a humanoid green monster that resembled a praying mantis. He was wielding two green scythes in his hands and used them to slash some innocent civilians next to him. This was Kamakiri, one of the higher agents of the Serpent Society.

"Find the Twilight Scroll! It must be somewhere nearby! Kill everybody that tries to get in our way!" Kamakiri yelled at the Dustards as they obeyed his orders.

Some hours ago, his master Orochi suddenly felt the seal of the legendary scroll being finally removed after a long time around this area.

And so, Orochi ordered Kamakiri to find the mystic relic, no matter what, and bring it to him.

"Hahaha! Orochi-sama will certainly reward me once I bring the legendary scroll to him." Kamakiri stated while sporting an evil grin.

"Hey, you! Stop this!" A voice suddenly called him from behind.

It was Asuka and her friends.

"Who are you? Why are you attacking everybody!?" Ikaruga demanded from him.

Kamakiri noticed that they all seemed to be shinobi in training, but simply scoffed at them.

"It's none of your business! Beat it! I don't have time to deal with some pathetic girls playing ninja right now! Get lost!" He yelled as he pointed his green scythes to them.

In response to this, the girls all decide to fight back against him by doing their Shinobi Transformations.

"Shinobi… Tenshin!" The five girls all exclaimed at the same time.

The Shinobi Transformation is a physical technique that uses the Attribute of Yang, in where the fundamental essence of the shinobi is used as a battle tool by releasing the body's internal spiritual energy in all six chakras simultaneously.

Using the technique produces a slightly different effect for each shinobi, but in general, their look and outfit will change and they'll be able to use all of their shinobi abilities. This quick outfit change can also be put to practical use in everyday life.

The transformation outfits aren't put on physically; rather, they're the manifestations of each shinobi's idealized appearance. These looks can reflect one's inner complexes or traumas.

The Shinobi Transformation also requires the use of a Secret Ninja Art Scroll.

Ikaruga's shinobi outfit consists of a white gold-trimmed jacket with six buttons and a few golden tassels strewed across. She has a Hanzou armband pinned to her upper left arm to signify her status as the class representative. She has a short gold-trimmed white skirt and

boots of similar colors to her jacket, accentuated by black tights underneath.

Katsuragi's outfit is simplistic; composed of her usual white Hanzō school uniform, unbuttoned, revealing most of her torso underneath; particularly her breasts. Along with a blue plaid skirt, she wears long socks and her signature black and gold metal boots adorned with small blue tassels on either side, serving as her combat weapon of choice.

Yagyu's new outfit is now a pale brown jacket over a white school skirt, red plaid skirt, brown loafers, and calf-high black stockings. Around her shoulders is a black mantle with a triangle design along with the trim and two extended tails.

Hibari's outfit is reminiscent of a student in gym class. She has a light pink track jacket with the Hanzō emblem on the left chest area, dark blue biker shorts, black and white socks, and red and white sneakers. Her eyes are peculiarly dotted with two pink, cross-shaped pupils.

As for Asuka, in her Shinobi attire, she dons a uniform composed of a yellow vest over a white shirt, and a green plaid skirt to match her tie. Paired with it are black thigh high socks with brown loafers, and on each arm is a guard with bandages beneath them. On her waist are straps to hold her swords, and in this form, she continues to wear her short red scarf.

When they were finally done, the girls all charged against Kamakiri.

"We will you stop you here and now!" Asuka and her friends exclaimed.

Back to Yukio and Junpei

When Yukio removed the seal, the scroll somehow emitted a blue light that immediately made it be linked with the Rider's soul. This now meant that the scroll officially belonged to him.

Soon after that, the scroll soon emitted a powerful shockwave that probably spread around the entire world. It must have alerted by now every single shinobi capable of detecting this level of energy of its existence.

Yukio and Junpei were about to begin studying the scroll when an alert about Kamikiri and some Dustards attacking the shopping district finally reached them. Probably searching for the Twilight Scroll.

"So it began. Now the Serpent Society must know about the Twilight Scroll being out of the hidden temple and that it is now in possession of somebody else." Junpei spoke, confirming their new situation.

"We're running out of time! Hanamura-san, I'm going!" Yukio said, quickly exiting the food truck and heading towards the direction of the battle.

'Good luck, Yukio!' Junpei thought as he watched the teen go.

At the battle site

The Rider soon arrives at the scene and lands on the roof of a nearby building.

He then looks to see that the Hanzo girls are actually having problems dealing with Kamakiri.

'I better hurry!' The ninja boy thought, frowning at the sight of all the destruction caused around the area.

Yukio takes out the bottle gourd around his waist as it starts to glow. He then opens it as a purple liquid comes out and forms the Shinobi Driver around his waist and leaves the Shuriken Starter in his left hand. It was the shuriken shaped device, with a purple arm attached to it, that worked as the 'buckle' for the Driver.

He then takes out a purple ninja star in his left hand and starts doing a series of hand signs, preparing to transform himself.

"Henshin!" The black-haired boy announced.

He then inserts the ninja star into the middle of his belt and spins it with his right hand.

A purple ninja scroll comes out of Yukio's Driver and opens itself behind of him, forming a large a ring. In the middle of the ring, a purple-colored seal script style kanji showing "仮面騎士忍" (it translated into "Kamen Rider Shinobi") appeared.

The kanji then turns into a big purple shuriken symbol.

[Dare ja?! Ore ja?! Ninja!]

*Poof!*

Next, assembling behind Yukio is now a giant mechanical frog. It opens its mouth, bringing out pieces of armor that surrounded his entire body, eventually slamming into him.

Kamui Yukio turned into Kamen Rider Shinobi.

Once the transformation was done, the frog disappeared into a puff of smoke while the scroll closed itself and went into Yukio's back.

[Shinobi kenzan!]

Now done, Shinobi heads straight into the fight.

Asuka was on one knee, panting and full of bruises, while her comrades were not looking much better and were scattered around the ground.

Kamkiri seemed to be someone considerably stronger that they couldn't defeat right now with their current strength.

The mantis-themed ninja calmly approaches her, looking sadistically at the female shinobi.

"Die!" He said, raising his scythe.

"Asuka!" Katsuragi called her.

However, before Kamakiri's attack slashed Asuka, Kamen Rider Shinobi quickly appeared before the two of them and easily stopped the monster. The Rider then kicks the evil warrior on the stomach, sending him away.

"*Gasp!* Who are you!?" Asuka asked, surprised at seeing Shinobi help her.

But the purple ninja seemingly ignored her and faced the opponent he just kicked away.

"Kisama! Who are you!?" The evil ninja demanded furiously after being interrupted.

"I'm Kamen Rider Shinobi. The thing you're looking for is right here! Stop your attack on this place!" Shinobi declared, showing the Twilight Scroll to the evil shinobi.

"If you don't stop your attack then I will destroy this right here and now!" He continued.

"What!? That's-!" Kamakiri spoke, widening his eyes in surprise.

"This Scroll has a powerful seal in it connecting to my soul! If you want to get your hands on it, you'll have to beat me in a fight!" The Rider announced.

Quickly recovering, Kamakiri told him while adopting an evil smirk:

"Very well! As you wish! I'll have you learn what it means to make yourself an enemy of the Serpent Society!"

"Bring it on!" Shinobi replied in defiance, storing the scroll back.

"Kamen Rider Shinobi..." Ikaruga muttered as she slowly got up.

"Who exactly are you…?" Asuka asked aloud as she helped her teammates.

"Dustards!" Kamakiri yelled as several of the black ninjas appeared from out of nowhere, quickly surrounding the purple Kamen Rider.

Shinobi frowned under his helmet as he thought:

'There are three reasons why I must win this fight.'

#1: To regain the past I lost!

A six years old Yukio, full of serious injuries, was being shown being rescued by a group of paramedics from some abandoned facility in the outskirts of a city.

#2: To rescue Hanamura-san's younger brother from the darkness!

Yukio imagined a brown-haired young boy close to his age that shared some of Junpei's physical traits. The boy was sitting lifeless on the corner of a dark room while hugging his knees.

#3: To find the one who gave me the courage to fight back!

'Hey, you! Don't give up! Don't lose hope!'

Yukio imagined a gentle voice calling his six years old self, who was full of bruises and gravely injured.

"Get him!" Kamakiri ordered the Dustards as they all charged towards Shinobi.

[Ninpo Kirisute!]

The Rider quickly brought out his Ninjato and began to easily slash all of the minions in a matter of moments.

He made some quick acrobatics moves and cart-wheels, managing to confuse them as he quickly kept dealing with the Serpent Society's minions.

There was a moment Shinobi got surrounded again by them but he quickly dispersed his enemies by using a series of breakdance likes moves, making a ruffle neck attack to kick all of the black-garbed ninjas away from him.

"Wow… Those moves..." Katsuragi spoke, sounding a bit impressed.

[Megaton Ninpo!]

Shinobi summons a giant tornado to lift all of his targets in mid-air. Once it's gone, all of the Dustards fall hard from the sky, finally defeated as they explode one by one.

*Boom!* *Boom!* *Boom!*

"Tsk! If you want something well done, do it yourself I guess… Not bad! Now let's see how you handle a true ninja!" Kamakiri spokes as he quickly appears behind Shinobi, trying to take the Rider down with a surprise attack.

But the Rider saw the attack coming and quickly defended from it.

*Clash!* *Clash!* *Clash!*

Shinobi and Kamikiri exchanges blow with each other as former's Ninjato clashes against the latter's pair of scythes.

"This ends here! I will never let you harm anybody else again!" Shinobi exclaimed to his opponent.

"Ha! Go ahead and try! It's useless! No matter what you do, we will win in the end! Once the Serpent Society finally gets the Twilight Scroll, we will rule this world with our ninjutsu!" Kamakiri replied back.

"Never! I won't let you!" Shinobi exclaimed back.

The Rider then quickly slashes Kamakiri's chest, making him wince in pain, and proceeds to deliver a series of fast kicks all around the evil ninja's body.

"Amazing… How strong is her? What sort of training he went through?" Asuka wondered as she and the other girls still observed the fight.

The Kamen Rider then punches the mantis ninja away, making the latter crash against some nearby trash bins.

"Unforgivable… You will pay for this! Long live the Serpent Society!" Kamakiri growled in rage, jumping high towards Shinobi.

"This is the end for you!" Shinobi declared, preparing to execute his finisher.

He begins to make a series of hand gestures as energy starts to be stored inside his soul.

Next, Kamen Rider Shinobi spins the shuriken in his belt and covers himself in a purple aura, now properly ready to deal the finishing blow against his opponent.

[Finish Ninpo!]

As his Shinobi Driver announced, the ninja Rider jumps in the sky.

"Ninpo: Rider Kick no Jutsu!" Shinobi yelled as he made a flying kick towards the green mantis-themed ninja, making his attack clash against Kamakiri's.

The two combatants clashed, trying to overcome each other. But it was for a short moment as Shinobi's kick proved to be much stronger and he eventually passes through Kamakiri, causing a great amount of damage towards the mantis ninja.

"B-Bakana! I lost!? Ahhh!" Kamakiri spoke, clenching his chest in pain while still in midair.

*Boom!*

His body then explodes and falls down hard against the ground.

As for Shinobi, he gracefully lands on the ground, on one knee.

He then got up and turns to look at Kamakiri's remains and tells, while pointing a finger at his defeated opponent:

"You have no right to call yourself a shinobi!"

[Victory Ninjutsu!] The Shinobi Driver announced.

With the battle finally over, Shinobi begins to walk away, to get out the scene, when a shout interrupts him:

"Hold it right there! You got some explaining to do!" Ikaruga says as she and the others walk towards him.

"Yeah! Like who are you? Are you a Shinobi? Your actions were quite flashy!" Katsuragi asks next.

But Shinobi pays no mind to them.

"Sorry, but I'm not interested in dealing with you right now. And my name is Shinobi. Kamen Rider Shinobi." He answers back to them with no emotion in his voice at all.

"Kamen Rider..." Hibari mutters.

"Shinobi?" Yagyu finishes.

Shinobi takes out a small purple shuriken and makes a series of hand gestures.

"Well, it's time for me to leave. Ninpo: Kuchiyose no Jutsu!" He stated as the shuriken in his hand began to glow.

*Poof!*

The item then dissipated while a cloud of smoke appeared next to the Rider. Once the smoke dissipated, something was now next to him.

Shinobi used a Summoning Technique that allows the user to transport a target to their location. The shuriken was the catalyst for it.

In this case, it was a black bike with purple flame details on both of its sides. It also had a symbol of a purple shuriken in the front. This is Kamen Rider Shinobi's personal vehicle, the Shinobi Chaser.

The Kamen Rider quickly gets on his bike, starting the ignition. Now ready to leave the area.

"Wait!" Asuka tries to stop him.

But the Rider ignored the brunette shinobi again and immediately drove away from them, finally leaving Asakusa's Shopping District while the girls watch him helplessly disappear.

He finally vanishes from their field of view, without leaving a single trace.

"Aw man. He got away." Katsuragi said, frustrated by this.

"I wonder though, who is he? Is he really a Shinobi like us?" Hibari wonders.

"I don't know, Hibari. I've never heard of him." Yagyu answers the pinkette.

"Me either. But the next time we see him, we must be ready to get some information out of him." Ikaruga says, agreeing with Yagyu.

"Yeah! I can't wait and maybe spend some time with him a little.~~" Katsuragi exclaims.

Ikaruga merely sighs at her antics

'Kamen Rider Shinobi… Why do I get this feeling that already I saw him before somewhere?' Asuka wonders, looking at the sky for a moment.

Meanwhile…

After Shinobi's escape from the Hanzo girls...

Yukio was now back at Café Hana, finally able to relax a little before going back to his dormitory room at Hanzo Academy.

"Welcome back, Yukio. Are you okay?" Junpei asks Yukio in concern.

"Yeah. Just a bit tired. I managed to beat that Serpent Society member and that's what matters. And now they will surely come after me since I revealed that I have the Twilight Scroll in my possession." Yukio explained while sporting a strained smile.

"Well, that was close. But I wonder why those Hanzo Shinobi girls were there earlier at the shopping district?" Junpei said and then sighs, not knowing what's going on.

"We'll figure it out later. Can I take a break here before heading back to my dorm room?" Yukio asks his friend, sitting on a nearby chair.

Shinobi Chronicles' - Ninpo 1 - My name is Shinobi! - End

Author notes:

Here was a brief introduction to another new idea that appeared in my head.

The story will focus on my new original character: Kamui Yukio and his adventures as Kamen Rider Shinobi.

Here's the summary for how this story is going to work:

In the past, ten years ago, a certain incident happened when Yukio was six years old, resulting in him becoming a shinobi and also obtaining the Shinobi Driver along the way.

The main reason he fights is to destroy an organization of evil ninjas, the Serpent Society, that wants to rule the world with their ninjutsu. They were also the ones responsible for ruining Yukio and Junpei's lives in the past.

Since Yukio is also a Kamen Rider, I decide to give him a signature Rider Kick as his main finisher and also a bike that he could easily summon whenever he wants with a Summoning Jutsu.

In regards to the Senran Kagura girls, he might not ally with either the good or the evil ninjas, mainly trying to stay neutral during their fights. But they might try to fight him in order to get the Twilight Ninja Art Scroll for themselves.

I'm planning to give some powers up to Yukio and my idea is that some Shurikens act as the main items for his transformation.

That said, he might be willing to help them sometimes and appear to assist the girls from the shadows while they all keep trying to discover his real identity.

So, what do you guys think? Please give me some reviews if possible.
