Hey, here's what you have all been waiting for… my new Den-O story! Oh and you'll notice some changes to my character that you've seen in the preview though.

I do not own Assassination Classroom or Kamen Rider Den-O

Timeline 1: A New World Time.

In a big wasteland, where there is sand everywhere, big canyons and the sky is strangely rainbow colored. An electric keyboard kind of tune played and a futuristic white and red bullet train appeared and three different colored carts was attached to it. This is the train of time, DenLiner.

Inside the train, the train was four beings and two people.

The first monster was red from head to toe with red body armor that had black markings on it. On his waist was a belt with a metal peach on it. His shoulder pads had spikes on them and his face looked like that of an oni with silver teeth, black eyes, and long red horns on his head. His name is Momotaros.

The second was donned mostly in bright blue armor that looked more like carapace in some spots. On each of his shoulders was a single hexagonal gray plate. His face seemed close to what someone would expect to see on a turtle. His eyes were a bright orange which caught attention whenever someone would glance at his face. His name is Urataros.

The third had a bulky body and was wearing a jacket with furry lining. His head was covered halfway with a helmet of some kind that had a horn sticking out of the forehead and a visor acted as a pair of eyes. He also pair of legs that looked just as muscular with boots. He was colored mostly gold with the helmet being black. His name is Kintaros

Finally there was the last monster. He looked like he had a large purple trench coat on which had black designs on it. He was wearing white gloves, purple pants, and purple boots. The shoulders had fins running from them as well. His head was purple and very dragon-like. He had both fins and whiskers running along the sides with a pair of horns on top of his head. A long braid of purple hair ran from the back of his head while it looked almost like he had a pair of headphones. His name is Ryutaros.

The fifth person is an elderly man wearing a suit, he has a cane and he's currently eating fried rice with a flag on it. This is the Owner of DenLiner.

The last person was was a young woman who was dressed in a tight waitress outfit consisting of black tight pants with white stripes, red heeled boots, a pair of red gloves and black sleeves that covered her arms, a white halter top that had no shoulders but still had a collar, a white cap on her head keeping her hair black hair with a pink streak combed back, and her arms were covered in a multitude of watches. Her name is Naomi.

In the past, Momotaros, Urataros, Kintaros, Ryutaros met an unlucky young man named Ryotaro Nogami and teamed up with him to protect the timestream from their own kind, Imagin, as a protector of time called Den-O. During their journey to fight against them, they met enemies, allies such as Zeronos and New Den-O, Ryotaro's future grandson and saved many people. Now Ryotaro retired and they had to count on his grandson to protect the timestream. They're still willing to help out at times, despite the fact that they constantly argue with each other despite being allies.

Speaking of which, what they're doing now it…

"Hey, you little brat! Come back here with MY pudding!" Momotaros yelled, chasing Ryutaros who laughed while holding up his favorite pudding.

"Moron, moron, moron, moron, moron...!" Ryutaros playfully said, avoiding the Red Imagin with ease thanks to remarkable flexibility and dance talent.

"They are as noisy as usual." Urataros commented while reading a book.

Kintaros is sleeping as usual.

Owner was simply eating his fried rice as always and ends with the flag falling down.

As this was going, the Denliner had suddenly shook causing them to stop what they were doing.

"What was that?" questioned Urataros, closing his book.

"Ah, it's probably nothing." Momotaros shrugged.

The train then shook again.

"This isn't good." said Urataros.

"Indeed it isn't." Owner said, slowly getting up from his seat and twirled his cane around. "Shall we check the Denbird to see the status outside?"

"Yeah, let's go!" Momotaros said as they ran to the Denbird. Ryutaros and Naomi were trying to wake Kintaros to let him know the situation.

Momotaros and Urataros got into the cart where the DenBird is at, which is a white and blue Honda XR250, and they see a black and purple portal.

"What the heck is that!?" Momotaros exclaimed.

"Who knows. But let's stop this train just in case." Urataros suggested.

"No need to tell me twice!" Momotaros got onto the bike and pressed the brake. DenLiner slowed down for a moment… only about to be dragged in. "What!?"

"Sempai!" Urataros went in front of DenBird and tried to help Momotaros with the brakes.

(Dinning Cart)

"Oi Kuma-chan, wake up!" Ryutaros said while shaking him.

Naomi placed a finger on her chin before getting an idea.

"Cry!" Naomi said, making Kintaros wake up.

"Cry!?" Kintaros got up and cracked his neck. "I'll make you cry!"

"Mou… Baka!" Ryutaros smacked Kintaros' head with a paper fan.

(DenBird)

"C'mon! Push harder!" Momotaros yelled as he and Uarataros were pushing on the brakes.

"I'm trying!" Urataros said.

Sadly for them, they couldn't stop the train on time and DenLiner got sucked into the portal before disappearing, thus making them no longer around.

(In another world)

Momotaros was on the ground, unconscious in a forest. Well instead of unconscious…

"Naomi… more coffee…" Momotaros said in his sleep.

"Sempai, wake up!" Urataros' voice called out.

"Shut up, you perverted turtle...!" Momotaros groaned in his sleep.

"Poke, poke, poke, poke, poke..." laughed Ryutaros as he was poking at the Red Imagine's face.

"Oi, cut it out already!" Momotaros yelled, slapping the purple Imagine's hand away. It took him a moment to realize that all of them were in some forest. "Huh? Where are we!?"

"I don't know, but look up there." said Urataros, pointing up at the sky, more specifically the moon.

"Wh-Wh-What the hell is this!?" exclaimed Momotaros.

"Ah, the moon!" cried Ryutaros.

"Hmm...?" questioned Kintaros. "Oh the moon is broken." he nodded before realizing what they had just seen and what he said earlier. "What!? The moon...?"

"It's broken! Broken Broken Broken Broken Broken Broken!" Ryutaros yelled childishly.

"WHAT THE HELL IS GOING ON!?" Momotaros yelled.

"Guys… I have a feeling that we're not in our world now." Urataros said, catching their attention before…

"EHHHHH!?" Momotaros yelled.

(Somewhere else)

At a rural area; a young man was laying down on a grassy slope. He had black hair that covered his ears, he also wore a school uniform, which is a gray coat with a black shirt, gray pants and black shoes. He opened up his eyes, which revealed that his left eye was the same color as a ruby and his right eye was the same color as a blue sapphire. His name is Neku.

Neku yawned a bit while stretching his arms.

"That was some nap." Neku yawned as he scratched the back of his head. Neku heard something and looked to his left to see someone that caught his attention.

The someone is a young petite framed boy with light blue hair and azure eyes, he could easily be mistaken as a girl if you don't know him. He was wearing a blue vest with a black tie, white shirt and blue pants with black shoes.

"Nagisa…" Neku recognized. He was about to call out to him before he noticed three other guys.

The first one has short, spiky, black hair which is dyed blonde around the sides. He has a bulky body which he uses to intimidate people with and green eyes. His name is Ryoma Terasaka

The second one has black hair, tan skin and black eyes. His name is Taisei Yoshida.

The third guy has dyed blonde hair and black eyes, he's also wearing the school uniform. His name is Takuya Muramatsu.

'What're those guys doing with Nagisa?' Neku thought before crouching down to the ground, deciding to watch before taking action.

"That octopus' face changes color with his moods, right? You're hanging around with that guy who said he'd be observing, aren't you?" Terasaka asked.

"So they're talking about him huh?" Neku whispered his thought.

Nagisa took out a notepad.

"Sort of. I remember that green stripes appear when he's calm." Nagisa started. "If a student gives an incorrect answer, his face becomes dark purple. For a correct answer, it becomes bright red."

'Yeah. I remember when I made a correct answer, his face turned red and that was only a guess.' Neku thought.

What's interesting is how after lunchtime…" Nagisa started.

"I don't need to know." Terasaka interrupted him before walking towards the blue haired boy and taking out a green combat knife. "I've got a plan. It's for when he's got his most [careless] face on, you'll stab him."

'What's he getting at?' Neku thought, not liking it.

"Me? B-But…" Nagisa stuttered.

"Don't pretend to be some goody-goody. We're Class E ain't we?" Terasaka reminded.

Terasaka isn't wrong, the school they go to, Kunugigaoka Junior High, is a prestigious private school located in Tokyo, Japan. It is renowned for being one of the top schools in all of Tokyo and has a high rate of successful students. The school itself is actually an academy as it also has a high school that the students of Classes A to D enroll to through an escalator system and students from other schools enter through a transfer student exam. However, Class E is a class of those who couldn't keep up with this school's education level, which earned the nickname [E as in End Class]. The classroom is a rundown school building up in a mountain and there, the students are treated no different than garbage.

Neku got out of his thoughts before looking at Terasaka, who was holding a small bag in front of Nagisa's face.

"No matter…" Terasaka grinned like a madman. "What methods we use to reach that goal." he gave it to Nagisa. "Don't screw up now, Nagisa-kun~."

Muramatsu laughed as the three left towards the building.

Neku sighed before he got up and went towards Nagisa.

"Nagisa!" Neku called out.

The blue haired boy noticed him.

"Neku…" Nagisa recognized before the different eyed boy stopped in front of him.

"Hey…" Neku said before catching his breath from the running. "I saw what you and Terasaka were talking about."

Nagisa looked down a bit before looking at his friend.

"Yeah, he wanted to know what I knew so far about our new teacher. But to be honest, I never expected that it would involve me in a plan." Nagisa said.

"Yeah, knowing those guys it would probably hurt you." Neku said as he scratched the back of his head while recalling about what Terasaka did in the second year at this school and on this mountain too.

Before the two can talk more…

*BOOM!*

Something landed onto the ground, kicking up a little bit of a dirt cloud and making a sound wave.

"Hello there, I'm back." Neku and Nagisa looked to see someone, or something with a male voice.

He has the appearance of an octopus. He is about three meters tall, and has a large, bulbous head with a large smile, beady eyes. He has two feelers as arms, with two fingers each. He wears a black academic dress, a small black square academic cap with a yellow tassel, and a black tie with a yellow crescent-shaped moon on it. Oh and he's carrying a missile for some reason.

"Okay, hi sir." Nagisa greeted a neutral tone.

"Welcome back." Neku greeted. "What's with the missile?"

"Oh, it's a souvenir." the octopus said. "The JSDF ambushed me in the sea of Japan."

Neku and Nagisa sweatdropped a bit. How did these guys get someone like him? Well there was a time, not that long ago, when the moon wasn't crescent shaped.

(Flashback)

Neku couldn't believe what he was seeing right now. Heck, the entire class was surprised to see something that's very unnatural in here. After all, it's very unnatural to see a yellow octopus dressed like a teacher with three guys, more like two guys and one girl, in suits.

"Hello~! How are you?" the yellow octopus greeted. "So… I'm the one who blew up the moon."

"Eh?" the E-Class students let out.

"Next year I intend to do the same to planet earth. But nevermind that now, I'm gonna be your new teacher. Isn't that exciting?" the yellow octopus asked.

'There are so many things wrong with this picture.' the E-Class students thought.

'And how is that octopus guy a teacher?' Neku thought that last part.

A grown man with spiky hair spoke up.

"I'm Karasuma, from the Ministry of Defense." the man named Karasuma introduced. "First of all, I would like you guys to understand that what I'm about to say is classified government information."

Karasuma sighed.

"Ah hell, I'll just come out with it." he said, deciding to get straight to the point. "I need you to kill this thing." he gestured to the yellow octopus.

'Kill an octopus that's literally standing in front of us?' Neku thought as he and the class gawked at him.

"...Er, what? So that guy is an alien who came to attack us?" Takuya Muramatsu asked.

"How rude! I was born and raised on earth you know!" the octopus exclaimed while his face turned red.

'Just how is an octopus who moves on land born and raised!?' Neku thought.

"I'm afraid I can't speak about the particulars, but what he told you is true. This creature who damaged the moon, will also destroy earth next march." Karasuma started. "The world's leaders are the only people who know about this. Before the world is plunged into panic, they are exerting considerable effort to kill him behind the scenes. In other words…" he opened the case in front of him and opened it up then took out a green combat knife. "An assassination." he swung the knife but to the students surprise, the octopus started to move at a REALLY fast pace.

'What the heck?' Neku thought.

"But at any rate, this guy is fast!" Karasuma started as he swung his knife but the yellow octopus moved as fast as it's going. "Far from killing him, I'm having my eyebrows trimmed by him! Meticulously, even!" Karasuma finished and creature really did trimmed his eyebrows. "He is a super creature possessing enough power to transform a full moon into a crescent. His maximum speed is actually Mach 20! In other words, if this guy were to seriously run away; we would be helpless until the day of our destruction."

'What!?' Neku thought in surprise and shock.

"Well, that wouldn't be fun at all. Which is why I made a proposal to the nations of the world." the yellow octopus said as he placed the trimmers away. "I don't want to be killed but…" he placed a hand on Karasuma's shoulder, which made the latter obtain a tick mark "If I become the homeroom teacher for Kunigaoka Junior High School, Class 3-E, then you're welcome to try."

'WHY!?' the E Class students exclaimed in thought.

'He's practically begging us to kill him…' Neku thought. 'But knowing some of these guys, they might want some sort of…"

"The reward for a successful completion is ¥10,000,000,000!" Karasuma interrupted his thought.

'Yen!?' the entire class thought, surprised.

'I stand corrected…' Neku thought, also surprised.

"It's an appropriate sum. After all the assassination's success means the Earth's salvation." Karasuma said before looking at the octopus teacher, who somehow obtained green stripes. "Fortunately, this guy is looking down on you. See, when the green stripes appear, it's his mocking face."

'What is he, a chameleon?' Neku thought.

"It's only natural. There's no way all of you will be able to kill me when the government couldn't. When they attacked me with a state-of-the-art fighter plane; I gave it a mid-air waxing instead." the octopus said.

'What's with the cleaning fetish?'

"I would like you to strike if the opportunity presents itself. We will provide you with the bullets and knives which are effective to him but harmless to you." Karasuma explained as two subbortanants of his came in with the bullets and knives. "This must be kept a secret from your friends and family. Time is short, if the earth disappears there will be nowhere to run!"

Neku, Nagisa and a green haired girl named Kayano had a look on their faces that looked uneasy. Especially to Neku, he doesn't even like killing at all because he's a pacifist. So for him it's gonna be pretty difficult even if the octopus can move at Mach 20.

"That's the long and short of it." the octopus clapped his tentacles. "Now everyone, let's spend this final year in a meaningful fashion!"

'I'll try but…' Neku looked down. 'There's no meaning when it involves killing, even if the world is at stake here.'

The octopus noticed Neku with that face, now thinking that he'll need to help the different colored eyed teen later on if necessary.

(End flashback)

"Must be tough, being a target and all." Neku said as the teacher placed the missile next to a tree.

"Nah, not really. The fact that I'm targetted by everyone is proof that I'm powerful after all." the octopus said.

"Yeah. Like I've heard that before." Neku said before the school bell rang.

"Well, 5th period classes are starting." the octopus teacher said as he was walking, with his tentacles, towards the old school building.

"Yes sir." Neku said before he noticed Nagisa with a down expression.

(With the Taros)

"Man, why the hell is the moon destroyed anyway?" Momotaros said as he and the Taros were walking downhill on a mountain towards town.

"Well that's what we're gonna find out." Urataros said.

"You think an Imagin is behind that?" Ryutaros asked as he did a few flips.

"Could be… however, a creature that can break the moon is gonna be our toughest challenge yet." Kintaros cracked his neck.

'What was your first clue?' the three Taros thought.

They soon made it down the mountain, but instead of there being a town; there's a school, a BIG school.

"Wonder who goes to this school?" Momotaros said.

"Oh that's Kunugigaoka Junior High." Urataros said.

"How did you know that?" Kintaros asked.

"There's a sign over there." Urataros pointed at the sign over there.

"How did I not notice that?" Momotaros scratched his head.

"Because you're a Baka." Ryutaros mocked.

"Can it brat!"

"No way, Baka-Momo!" Ryutaros continued to mock before Kintaros covered both their mouths, Urataros noticed a male student on his phone before the blue Imagin possessed him. The student became calm his hair turned straight with a blue streak, his eyes turned blue while he obtained glasses.

U-Student then walked towards the Taros.

"The hell are you doing Kameko?" Momotaros asked.

"Oh, I'm just gonna obtain information on the broken moon and anything that could possible be related to it." U-Student said before he started browsing for info.

"That's actually a good idea." Momotaros placed his right fist into his palm while Kintaros fell asleep on Ryutaros.

Neku and his classmates were staring at the octopus teacher in slight fear. Earlier, Nagisa walked towards the octopus making him think that an assignment for a poem, which is suppose to end with 'was tentacles all along', and the blue haired boy made a failed attempt to stab the teacher before he hugged the creature and Terasaka pushed a button on a device before Nagisa exploded, literally. He actually filled a toy grenade with gunpowder and some Anti-Sensei BBs

The entire besides Terasaka and his group class got worried.

But they found out that Nagisa was unharmed due to what they thought was a corpse but it was revealed that the teacher was still alive and kicking, it turns out that what protected Nagisa was his skin which he sheds once a month. His face turned black before going out of the classroom and coming back with nameplates of each of the students on where they live. That made both Neku and Nagisa realize that the only way out of this situation was to kill him… even if the former didn't like it.

"Y-You're a real pain in the ass! COMING HERE ALL OF A SUDDEN WITH YOUR 'I'M GONNA BLOW UP THE EARTH' AND 'ASSASSINATE ME' AND ALL THAT…" Terasaka, who was on the ground, accused. "WHAT'S WRONG WITH USING AN IRRITATING KILLING METHOD ON AN IRRITATING GUY!?"

The octopus' head turned bright red with a circle.

"Irritating? Nonsense, your idea was excellent." the octopus teacher reached his tentacle out to Nagisa and patted him on the head. "Especially Nagisa. You get a perfect score for keeping the movement of your body entirely natural until the moment you closed in. You attacked me at a magnificent opportunity."

Nagisa was surprised while Neku was glad that their new teacher wasn't mad now.

"However, excluding Mr. Neku." the octopus teacher's head turned purple with an X. "Terasaka and the others held no regard for Nagisa's welfare. Students like that do not have the right to kill me."

"Excluding me?" Neku asked.

"Of course, after all you tried to stop Nagisa a few seconds before the grenade blew up." the teacher said to him.

"Well somebody's gotta be a good friend for this guy from blowing himself up." Neku said.

"Somehow I don't want to hear that from a guy that always get bad luck." Nagisa said.

"Name one time."

"This morning you stepped on a can and then fell on your head." Nagisa said.

"Name three times." Neku said.

"You fell down a manhole, got stuck up on a tree with a bicycle and yesterday bird poop fell on your shoulder." Nagisa counted.

"Okay, I'm very unlucky." Neku said with a comical depressing aura.

"As I was saying…" the octopus teacher said, getting everyone's attention. "Let's have an assassination that will make people smile and puff out their chests with pride. Each and everyone of you can do that. You are talented assassins with hidden strength. That is advice from your teacher, as a target."

Neku sat back down at his seat.

'I don't actually like to fight or killing, but I guess it wouldn't hurt to try.' Neku thought as the octopus teacher took out a burning mark on the teacher's desk.

"Now then, here's a problem for you Nagisa." the octopus teacher started. "I don't even have the slightest intention of being killed, because after enjoying my time with all of you until March, I'm going to blow up the Earth. If you don't want that, then what will you all do?"

Nagisa thought about it for a moment before smirking.

"Before that happens, we're gonna kill you." Nagisa said.

"Nurufufufu~." the octopus laughed while his head obtained the green stripes. "That's the spirit." he then turned to all the students. "No one leaves until I'm vanquished!" he joked.

'You're kidding right?' Neku thought after the classroom complained about that.

Nagisa went back to his desk and took a quick peek at the teacher, who sat down at the desk at Mach 20 and started cleaning the nameplates.

That proves one thing, we're assassins and our target is our teacher whether we like it or not. Ah well, that's life… even if we gotta take a life which is kinda odd in my opinion. While the class has their assassination weapons out, I overheard Nagisa and Kayano talking about the Japanese word for unkillable, they must be figuring out what name what would be good for the octopus teacher. I was proven right when Nagisa said the perfect name for him.

Koro-Sensei.

Honestly, that feels like the right for him. Just us vs Koro-Sensei for the fate of the world.

Here, in our Assassination Classroom.

-Neku

(With the Taros)

"What did you learn so far?" Kintaros asked Urataros, who unpossessed the student.

"Well so far I've learned that the destruction of the moon happened a few months ago." Urataros said while he was leaning against a tree. "However, the cause of the moon's destruction is currently unknown."

"So we're at a dead end here!" Momotaros groaned.

"Not exactly, there were also sightings of some yellow creature that looks like an octopus that can fly around town."

"Flying octopus? Kameko, you are not making any sense." Momotaros said.

"That's because you're a moron, Baka-Momo!" Ryutaros playfully said.

"Be quiet brat!" the red Imagin barked.

"No way, Baka-Momo!"

"Anyway!" Urataros said, catching their attention. "We need to find a door back to DenLiner and a way back home."

"I wonder how Owner's doing…" Kintaros said.

(With Neku)

Neku just packed up his school supplies in his bag. He then went out the door and sees Koro-Sensei bidding some students farewell while he was watering some plants.

'That guy is good with plants despite him being the future destroyer of the world.' Neku thought as he walked passed him.

"Neku." Koro-Sensei called out to the different eye colored teen.

"Hm?" Neku stopped before he noticed a silver star necklace in front of his face, being held by his teacher.

"If what Nagisa said was true about you being unlucky a bunch of times, here's this to hopefully improve your luck." Koro-Sensei said.

Neku stared at the necklace before taking it.

"Thanks Koro-Sensei." he placed the necklace in his pocket before running off. "See ya!"

"Have a pleasant evening." Koro-Sensei said before he went back to the flowers.

Neku ran down the mountain while he was placing the necklace around his neck… until he tripped on his shoelace and fell down onto the ground making him roll down the mountain. The rolling eventually led him down to halfway towards the bottom of the mountain and crashed into a tree.

"Ow…" Neku groaned in pain before he slowly got up. "Well at least it improved by a little, usually whenever I trip I hurt my skull. But this time it's my forehead."

Neku laughed slightly before he started to walk away while rubbing his forehead. He soon made it down the mountain and near the main building… until he stepped on a can which made him slip and fell on his back.

"Ow…" Neku groaned, again, and notices the can. He then noticed a couple of students that he never knew in a group and he noticed one of them snickering. 'Of course someone from the other classes would do that on purpose.'

Neku got up before he grabbed the can and saw a trash can. The different eyed teen threw the can at the trash can, but it bounced back and went towards one of the students then it hit him on the back of his neck.

The students, who look like they're from D-Class stared at Neku before the different eyed teen ran away.

"Get him!" the leader of the group said before they ran after him.

(A few minutes later)

"Man these guys are persistent!" Neku groaned. He then tripped on his left heel, making him fall to the ground. "Crap!"

The D-Class students caught up to him and the leader grabbed his collar.

"Can't we just talk?" Neku said before… the D-Class students and him got whacked by some some sort of whip making the students get flown away while Neku was sent towards a wall. The different colored eye teen looked to see some sort of creature that resembles a chameleon.

The D-Class students ran away in panic at the sight of it while the Chameleon Imagin sees Neku about to run away.

"You're not getting away." the Chameleon Imagin said before running after him.

Neku was running but he tripped again and he sees the Chameleon Imagin and he blew fire at him, Neku rolled out of the way and was about to run again but the Chameleon Imagin whipped his back.

'C'mon! Can my luck ever get worse!?' Neku thought as he crawled backwards away from the Chameleon Imagin a bit before…

*SLASH!*

The Chameleon Imagin was suddenly slashed on the back and was thrown aside by Momotaros.

"Man, I don't who wished for this kid to be hurt but that's pretty low even for you." Momotaros remarked.

"Who the hell are you!?" the Chameleon Imagin exclaimed.

Momotaros looked at Neku.

"Hey kid, I'm gonna have to borrow your body for a moment." Momotaros said.

"Huh?" Neku questioned.

Momotaros turned transparent and jumped into Neku, causing him to make his sapphire blue eye to turn red and his hair spiked up and has a red streak.

M-Neku got up from the ground and he got something that looks like a black pass out on one hand and a belt in the other. The belt had a red, blue, yellow, and purple next to a circle that had a T with a tip pointing to the right. He placed the belt on and pressed the red button which soon played an electric keyboard kind of tune.

"Henshin!" M-Neku announced as he swiped the Pass over the circle.

"SWORD FORM!"

Red pixels came out of the belt before forming up on M-Neku. M-Neku was now donned in a black bodysuit with a chest plate is black and white with the white parts higher up with a silver line in the center that looks like train tracks. The helmet has a silver line running down the middle with a silver mouthplate and black eyes. This is Kamen Rider Den-O Plat Form.

Soon red pieces of additional armor then appeared on his shoulders and chest as well as black armor trimmed in yellow snapped to his back. A red metal peach slid over the helmet and snapped onto the front before splitting in two, the points extending to become antennae and the two halves of the peach now resembling eyes. This is Kamen Rider Den-O Sword Form.

(Kamen Rider Den-O OST: Double-Action Sword Form)

"Ore… Sanjou!" Den-O SF announced while doing his pose.

"Den-O!" the Chameleon Imagin growled.

"Huh? What's going on!?" Neku exclaimed in his mind.

"Ah! You're a Singularity Point!" Den-O SF said.

"A what now?"

"I see, so you just unknowingly possessed a Singularity Point?" the Chameleon Imagin said.

"Shut up!" Den-O SF said. "Look, I'll explain this after we beat this guy."

"…Alright. Just don't hurt my body too much." Neku said.

Den-O SF smirked.

"Good. Now listen here ya tokage(lizard)-yaro, From the start to the finish, I'm at a climax!" Den-O SF declared.

The Chameleon Imagin used his whip at him, but Den-O SF deflected it and he got two metal pieces then placed them together then tossed it up in the air and grabbed two more pieces then jumped into the air combining them, which turned it into a sword. Den-O SF then went down to the ground and slashed the Chameleon Imagin, causing sparks to come off.

Den-O SF then slashed the Chameleon Imagin twice and easily dodged an incoming strike from him before he slashed the green Imagin multiple times, which made the Chameleon Imagin to roll on the ground. He used his whip to strike him, but Den-O SF slashed the incoming whip with ease and slashed the Chameleon Imagin multiple times again, making him fall on his back.

"Now it's time for my Climax!" Den-O SF announced as he got out the Rider Pass and placed it over the belt.

"FULL CHARGE!"

Red energy came from the belt and went towards the sword. The blade then flew out of and floated in the air.

"Hissatsu! Ore no hissatsu waza! Part 2 dash!" Den-O SF then swung the bladeless sword towards the Chameleon Imagin. The floating red blade followed its arc and put a large cut onto the Chameleon Imagin. And with that the Imagin exploded.

(End Song)

"How was that a dash?" Neku said.

Den-O SF ignored that comment and took of his belt, making him revert back to M-Neku. The possessed teen checked his watch before smirking and started to walk at another direction.

"Hey, where are we going?" Neku asked.

"The place I crash at." M-Neku said and, as if on cue, DenLiner appeared from a rainbow colored portal and stopped near him.

"Whoa…" Neku said in awe as M-Neku entered a door.

M-Neku just entered the dining cart of DenLiner before Momotaros jumped out of Neku. The different eye colored teen noticed the other three Taros along with Owner and Naomi.

"Naomi! Coffee!" Momotaros said as he sat down at a table.

"Hai~!" Naomi cheered before preparing his coffee. Neku, however, looked around DenLiner and checked outside the window only to see that the entire train is somehow in a wasteland.

"You're very curious, aren't you?" Owner said as he caught Neku's attention.

"Well yeah. I'm also surprised to see a creature that tried to attack me and another one possessed me to turn into an armored warrior. Which is something I'm also curious of." Neku said.

"It's only natural for some people to be curious." Owner said as he took a bite out of his rice.

"Yeah." Neku said before looking at Momotaros.

"What?" the red Imagin asked after noticing that look.

"I want an explanation on who you guys are but…" Neku bowed politely. "Thank you for saving my life."

"No problem kid." Momotaros waved it off and Naomi served him his coffee. The red Imagin took a sip before looking back at Neku. "You got a name?"

Neku stood straight and nodded.

"It's Neku… Neku Nogami." Neku answered.

That caused Momotaros and Urataros take a spit take from their coffees while Ryutaros messed up his coloring and Kintaros woke up to that.

"EEEEHHHH!?" the Taros yelled.

'The heck…?' Neku thought.

"NEXT TIME ON ASSASSINATION DEN-O!"

Neku: You guys are from another world!?

Momotaros: So we gotta kill that octopus?

Karasuma: This classroom is currently the only place where he can be killed!

Neku: This school is not only strict, but it also has a system where you can be discriminated and treated as the lowest of the low.

Koro-Sensei: Allow me to give you advice as your teacher.

Neku: I really hate fighting and killing, but after what I've been through; I really have a choice but to fight.

Momotaros: Teme, Tako-Sensei!

"TRAVELING THROUGH TIME, HERE I COME!"
