AN: I am back with another one, hurray! I have been trying to figure out how to make the AN's even more noticeable for some people but whatev's. I have tried a lot of different mehtods now I am going to use the gosh darned underline and bold tactic, XD. I have news for a lot of people, I am writing planning out two different Fics at the time of this one, One is another Hero Academia crossover while the other is a Nanatsu no Taizai story, with inspiration from DMC remake, in regards to the Nephilim. I always loved tropes like that, I find them rather enjoyable to write about and all that, but that one is focused on an OC who will be exploring the world on her own. She is a new character I created and I personally love her. I love Saphria like she was my own kid, same as the new OC since I can create them and give them life, but they just sort of do what they want while giving me the finger and doing the exact opposite of what I want!

I wish to apologize to the few readers who dislike my OC and how much she is included in the story, I know that it isn't possible to please everyone but I would be lying if I didnt say that it doesn't sting being told that Saphira is a unnecessary character, but I wanted to address this issue while I was still in the writing mood, I know that she is difficult to actively like but know that in the end she will be important. That is all I have to say on the matter ok! I will be continuing this story until I actually finish it. I hope with the addition of Charlotta will be able to more or less keep her stable in lack of better terms..

Anyway, enough of that. I am going to be attempting this chapter and giving it a good run. Please note that I am going to be doing a time skip to the USJ incident since I didn't have anything really planned for after the last chapter. I wanted to give myself a push and please know that this is going to get dark for a while after this and please don't hate me! Well, I mean I dislike myself enough for everyone, XD!

(P.s. are there any good songs that people suggest to me to listen to while I write, since it is difficult for me to focus without noise, since I grew up in a loud ass environment. I am kinda partial to rock and anything with a good beat and lyrics, so to sum it up I am open to any and all suggestions, show me some good stuff people I live for good music.)

Chapter 15: The Desire

POV: (Izuku Midoriya)

Izuku held tightly his Notebook as he looked through the pages in horror, he lost himself in a daze after the match and was currently rushing his way towards All Might's office. He had his normal notes in the book with how he analyzed other Quirks but there was a slight difference in these pages. He had gone back through the notebooks and found that he was gauging whether or not these Quirks would be useful for him or not. He had Pro Heroes underlined with a plan in order to acquire their Quirk be it through accident or planned meeting. The thing that was unsettling him the most was how he planned to take their Quirks through force or tricks. Even using the newly gained Quirks to gain even more Quirks.

Izuku sat in All Might's office while he waited for All Might to come and talk to him about his behaviour during the match. He himself couldn't find the fault with his borrowed Quirk of Beastblood. It couldn't be that, since it was a copy he shouldn't be experiencing the same issues that Saphira did when using the Quirk and to be honest some of the things make sense when he is using the actual mutant part of the copy. The need to take Quirks is starting to build up, he didn't know what it was about having a full Quirk but every copy he made seemed to satisfy the need ever so slightly. He thought back to the combat practice that he nearly took the full version of Bakugo's Quirk.

Izuku ran down the stairs as he called out for Mina, while he knew that she could take Kirishima in a fight. He didn't want her to deal with everything on her own. He felt a growing sense of discomfort the farther away he got away from Kacchan. There was a… sense of need trying to pull him back to his downed childhood friend turned bully. He kept his eyes forward trying to keep moving.

He heard the sounds of shouting and he knew that it wouldn't be long before the time limit passed and the opposing team won the exercise. He took a deep breath and ran, seeing the hallway lose some of the color as he ran faster than the light was able to reach his eyes and show the full color of the walls. He moved as fast as possible to the area he heard the noise of fighting go.

He saw Mina and Kirishima facing one another across the room, Kirishima had a good amount of acid covering his arms. It was probably the itchy type, given how red the surrounding skin was turning. Izuku moved as fast as he could, feeling his body reaching the time limit for his speed. He ran towards Kirishima and could feel Thief activating before he could process it. He shoved his hand into Kirishima's back and grabbed what he was looking for, his Quirk.

His mind entered that same place as he took one look at the Quirk that embodied Kirshima's Hardening. That is when he felt something akin to desperation slam into the back of his mind as his Quirk attacked the gray orb floating in the darkness. He could feel the desire to take what should rightfully be his and his past feelings of being Quirkless hit him, the extreme desperation he felt as a child, praying that he could still develop a Quirk. His Quirk snaked out and squeezed Kirsihima's Quirk, the need to consume the whole thing was there.

Izuku had to strain and force it back, while only taking a copy. The new quirk, even if it was a copy, seemed to ease the urges back. He awakened back into the present, pulling his hand out of Kirishima's back and smiling when he hardened his fist. He now had a more frontal assault option and a slight defense providing quirk. He could work out his new limits later as he reared back his fist while offering a silent apology to Kirishima. Izuku's fist slammed into the back of Kirshima's Hardened skull. He could see Kirishima slowly starting to fall forward, his eyes closing slowly.

He moved to Mina's side, the feeling of his body tearing itself apart was growing stronger. He turned off Quicksilver when he reached her side.

"I'm here to help!" Izuku exclaimed while he gave Mina a thumbs up, showing that he had taken care of his part of the plan and together they gave Kirishima one good fight.

Taking the mock bomb was easier than thought because that initial punch that Izuku had thrown had knocked Kirishima's Hardening down a peg, leaving the rest of the fight with him so much easier.

Izuku shook his head out of the memories of the fight. The entire focus of the fight revolved around his need to end it quickly, and Mina's help certainly pushed it along. She is an amazing girlfriend to him and she certainly helped him focus on what was important.

He only couldn't shake that he shouldn't rely on her too much, especially when he needed to fix what was wrong with him. He could understand the issues that came with Saphria's Quirk, thinking of enemies as prey and confusing allies for prey as well. The entire thing was more of a berserker type quirk, one that allowed for a super combat orientated Hero. The thing that didn't make the most sense was his want to take Quirks from people. It was one thing for it to be Kacchan, but then there was Mineta. He was angry at him sure, but why would he want to take his Quirk. Then there was Kirishima who seemed like he was an OK guy, talking to him before the start of the exam. He couldn't see a reason for him to try and steal his entire Quirk out from under him.

"Midoriya why are you here?" He heard the familiar voice of All Might as he pushed open the office door. The giant of the man seemed to be straining in a way as he walked into the office and sat behind his desk. "I was informed by Aizawa that you wished to talk to me about something."

"I want to talk about my Quirk with you." Izuku said, his voice straining under the pressure of keeping it together.

All Might entered the room with a smile on his face but his eyes watched him warily. "I know you wanted to talk about your Quirk but I didn't expect you to come to me."

"Your the only one I could come too! I nearly stole Quirks from my classmates and I could barely stop myself!" Izuku exclaimed loudly while he gripped his knees, staring at the notebook that laid in his lap. "I don't understand why my Quirk is like this!"

"What do you mean, Midoriya?"

"I can feel a desire to take Quirks from people, it doesn't matter how little or unimpressive the Quirk. My mind jumps to how I could use it better than the ones who are using it. I could chain multiple Quirks together in order to use them in a fashion that no else could. For example, for Mr. Aizawa I could take his erasure Quirk and combine it with a Quirk that doesn't require me to blink. I could have an always active erasure field in my line of sight. No one would be able to fight me, because I could combine that with Saphria's Quirk making my strength a lot greater than an average person's letting me steal as many Quirks as possible." Izuku said his knuckles turning white as his mind raced at the horrible notes that he wrote down, the only thing that made it worse was that he couldn't remember writing them.

"Are your desires something that defines you as who you are?" All MIght asked with a hard smile on his face as he considered something. "Do you want to act on your desires?"

"N-no, it wouldn't be right for me to do that."

"Let me tell you something about desires, young Midoriya. Every Pro Hero has a desire that they use as their motivation, while some desires aren't the best of them, it's what helps them strive to better themselves. Now there are some Heroes who push themselves forward without giving in to their desires and ignoring who they truly are on the inside. The result of them ignoring who they are is dangerous, they start cracking down on others harder than they should, because soon everyone who does something that doesn't sit with their Ideals will become targets."

"B-but isn't it wrong to want to take things from people?"

"Hmmm, I can see your dilemma but look at it from a different perspective. If you see a child with a knife, what is it that you want to do?

"Take the knife from them."

"There you go, now if there was a dangerous villain who could hurt people without ever leaving his jail cell what would you do in order to prevent people from getting hurt?"

"I would use my power to take his Quirk from him, make him less dangerous and use it for myself in order to make the world safer." Izuku said, slowly feeling better with himself.

"The only thing I worry about is that you feel that your desires are wrong, but there is nothing wrong with wanting more power. It is only how you gain the power and how you use that power is what matters." All Might said while he pushed himself from his desk, and stood with a mighty flex. "True Heroes will do whatever they can to ensure the safety of the public!"

"Thank you, All Might!" Izuku exclaimed with a smile on his face and tears building in his eyes. Izuku stood from the seat and moved to the door, he left before his mentor could see the tears that were going to go streaming down his face.

'I'm not a monster!' He thought to himself as he moved down the hallways with no true purpose.

POV: (All Might)

As soon as Izuku left he dropped his muscle form, taking in a deep breath as he moved to the door locking it.

'That was terrifying, I thought I was going to screw up somewhere!' Toshinori thought to himself with a grimace on his face. Izuku was a good kid and he honestly couldn't believe he could hurt a fly. He was going to have a difficult Hero path in front of him, the life of a pro wasn't something that he would wish on anyone. The idea of how many people lose their lives in some fights and situations. He couldn't save everyone and he knew it was impossible for someone who's power let him punch rain into the sky. He wouldn't have the slightest clue what to do for someone with a bullet wound, he could get them to a hospital but even then he had to make sure not to jostle the victims around.

"I need to keep my time limit in mind, otherwise I'll start flying through it without a thought and end up making more trouble for everyone around me." All Might whispered to himself, while he clenched his skeletal hands together with a grimace on his face.

He heard rustling in the ceiling and with a small frown he looked upward as a body fell from the ceiling, as soon as he looked up the tiles fell inward and a body slammed into the floor in a heap.

He recognized the old duster and leather hat that the body was wearing instantly.

"Why?" That was the only thing he could ask Saphira as she lazed on the floor with the white dust from the broken tiles on her.

"I heard you lock your door and so I climbed in from the ceiling."

"You could have knocked like a normal person…"

"That seemed boring." She drawled in a bored tone, a sour look crossing her face. "Besides you enjoy my company and a few other teachers here know about the whole corpse looking thing." She gestured at him with a small wave of her hands.

"Fair enough," Toshinori sighed while he sat in his chair, his office was in good shape it felt like an old school principal's office, with a couch and everything. He suspected that Nezu gave him the couch so after classes he could come here and kick back for a while. It was getting to be a boon working here, since the other heroes are starting to take care of crime without his help. He still couldn't help himself in the regard of running into danger to help even with his time limit becoming shorter and shorter. He couldn't help but think about his former sidekick Sir Nighteye.

He had to find a suitable host for One for All, he was losing his ability to even use his ability correctly and to its full extent as well.

"I came to ask some questions about the USJ." Saphria said pulling herself into a seated position on the floor. "What exactly are Charlotta and I supposed to help you, Thirteen and Aizawa with?"

"Well, you two are going to play the roles of the villains and keep the students from saving the hostage dummies. I believe Nezu said something like, make them think for themselves and teach them to never become complacent in their abilities."

"Oh, sounds fun! What exactly am I allowed to do?"

"If I remember correctly you are supposed to be the runner, following the students and making life hard for them. Charlotta is going to be positioned in the fire zone, she is to keep the students on their toes and keep them off balanced."

"Ok and my beast form, am I trusted enough to use that?" She drawled with a look of appraisal aimed at him. It was slightly unnerving how the sheen in her eyes told him that she was anything but sarcastic.

"Yes, it seems like Aizawa gave you a seal of approval."

"Seriously! I thought that guy hated me or something."

"He does, but he says that you seem to be able to contain most of your killing instinct. He did mention that you do tend to run wild but he thinks that you are mostly in control." He answered with a small smile on his face.

"Yippie! Does that mean I can use my scarier forms?!"

Toshinori felt a small amount of sweat forming on his forehead, "you have multiple forms?"

"Yup, one for every occasion. I can't just have one form, it would be super lame and my mom had more than one as well remember?"

He could definitely remember that, but he figured that she was only capable of two had she been training it up for more and if so why didn't she inform Nezu?

"Well if the occasion calls for it, go for it." He said with a shrug, he knew she could hold herself back enough to only capture the kids not kill them.

"Sweet, I've got some preparations to do! I'll see ya later corpse!" She exclaimed with a sickly sweet voice as she bolted out the room, leaving him with the mess from the ceiling to clean up.

POV: (Izuku Midoriya)

He was walking with Mina to the train station so they could catch the ride back to their respective home. She was talking animatedly about how the two of them took down Kacchan and Kirishima. He was holding her hand as they walked, the minor display of affection didn't bring him to the edge of bursting into flames which he was honestly grateful for.

"Hey, are you doing alright?" Mina asked as she looked at him, her gold irises locking him in place. He realized that he was lost in his own thoughts for a while as they walked barely contributing to the conversation.

"Y-yeah just worried about Kacchan. I did kick him in the head and also knock him unconscious…" Izuku trailed off as he rubbed the back of his awkwardly.

"Well it's not anything he didn't deserve. He doesn't deserve to be called "Kacchan," it's not like he is friendly towards you at all. What would you have done without me?" She said with mock frustration.

"I would have suffered until I was able to take the exam for U.A then I would have met you anyway." He said with a smile in Mina's direction, she looked away for a moment her cheeks a darker shade of magenta.

"O-ok, that is a good answer." She murmured quietly as she pulled his arm closer.

Izuku felt his face burn at how close his arm was to her chest, but he kept his face focused forward leading them through the crowd to the station. He wanted to talk to her about his Quirk and how many times he had to stop himself at school, but while she was with him, he knew that he would be ok and there was always another time.

"You know, as long as we can keep working we can help push each other's dream. We both want to be heroes who can save people." Izuku says while he keeps his eyes forward, "and I'll always be there to stand by your side, especially since you were the first to believe that I could become a hero before I discovered my Quirk."

"I know that, there's no need to tell me something I already know about you Izuku. You are the best boyfriend ever!" She said while she placed a small kiss on his cheek.

Izuku's face turned bright red as his blood rushed all the to his head, he could feel steam rolling off his face as he looked at Mina who was still blushing but she was sporting a huge smile on her face as she looked up at him.

"Even after all this time, you are still so easy to tease!"

"W-well, it's your fault for being cute." Izuku felt his brain turn off as he uttered that last line, he stammered as he tried to explain while Mina just started laughing at his panic.

Time skip: The USJ

POV: (Izuku Midoriya)

Izuku sat on the bus to the trip sitting next to Mina, they were on their way to the USJ. The training facility was a good distance away from the school so they had to make use of the bus to get there. The entirety of Class 1-A was shoved into the bus, Aizawa claimed the seat closest to the front and fell asleep the second he sat down. The other teachers were already on site, waiting for them and getting everything set up.

"It's kinda weird how far away it is from the school, I mean why not do the training in the school. The huge underground training grounds in Saphira's classroom was a big enough place for everyone to learn how to do rescue training. It could be due to the fact that it is only a city landscape and that isn't the only training they want us to do."

"Izuku, breathe." Mina whispered to him, causing his teeth to click shut as he shut down his mutterings making an audible hiss. "It's alright to be nervous, just try to keep a good hold over it. We don't want to make everyone else here nervous."

"R-right, I understand that. It just feels like a waste of time to make us go from the school to a separate area. It would be better to just have it made into the school, similar to how it is for Saphira." He whispered back, making MIna nod with the line of thought he was going with. It seemed like she understood what he was talking about.

"You do have a point. It could have something to do with the amount of teachers that we have coming with us. They must have something special planned for us."

"We'll just have to wait and see," Izuku thought for a moment as he looked towards the large structure in the distance. "I'm still trying to figure out what to do in regards to my Quirk, which should I use and all that."

"I think some training with just Thief would be useful, especially if you could get so good with it you don't even need to think about activating it!" She exclaimed softly, trying to avoid waking up Aizawa.

"Yeah, that does sound like a good idea." Izuku said with a smile. 'Then I could actually control some of the urges as well.'

They arrived at the USJ soon after, the entire class was abuzz with excitement and everyone was wearing their own hero costumes. Izuku was wearing his own clothes, which were just fine but he patted his pocket sadly. The hero support did not have enough time to procure him some blood syringes. He didn't think he would get hurt while training today, but it never hurt to be prepared.

"Welcome to the USJ, Children." Thirteen said in excitement. Izuku already knew about her Quirk and her suit was used to contain her black hole. In order to not hurt anyone. Aizawa took his place next to his fellow teachers, Saphria and Charlotta were standing slightly behind Thirteen. Saphria had an annoyed scowl on her face as she looked at her phone.

He found himself wondering how it would work for him, if he copied it. It would be interesting to summon black holes that he could use to pull criminals closer to him. He stopped that line of thought as he felt Mina's hand brush against his.

There was always later, he could ask her if he could try to copy it another time.

"You are here to take part in the rescue training and while it is going to be mostly focused in certain areas. We will be using data from your performances in order to find areas that you can stand to improve in."

While Thirteen spoke Izuku saw Saphira freeze in place. She raised her head and took precautionary sniffs in the air, as if something wasn't quite right.

Izuku felt his own nose flare and a quick sniff found something foreign in the air. The smell was hidden underneath the smells of the entire class, it all mixed together in order to mask it, but it was present. It smelled like something was decaying in the air as well as a slight undertone of blood. It was sickly sweet to him and he found himself turning his head towards it.

It was then that the space was filled with a dark fog, it was so dark that it obscured everything behind it from sight. That's when he saw the yellow eyes that peered from the fog, they were huge.

People were leaving its inky depths, all walking in the light. There some mutation type quirks among them, making some look horrific in appearance while others seemed to be somewhat normal. The rest of the class saw them and everyone was shocked.

Thirteen, Aizawa and Charlotta were stunned as well, while Saphira was looking at her phone. She snarled as she put the phone in her pocket.

The scent of decay seemed to grow even stronger, as well as the scent of blood.

"What All Might isn't here!" One of the people exclaimed, he had hands covering him. He was starting to scratch at his neck viciously as he looked towards the heroes. "I came here to fight the final boss, but instead got a bunch of mobs!"

That's when everything went to hell.

Kacchan and Kirishima rushed them but before they could even lay a hand on them they were yanked backwards by Saphria. She moved so fast in order to keep them from making too much distance.

"So what do you want?" She asked standing in front of everyone, while holding her gun.

"MOV-" Kacchan went to scream at her but was silenced by a stern look from her. She was promising death, Izuku could see the difference in her stance. Saphira wasn't about to start playing with these people and was in no mood to deal with any issues.

"Isn't it obvious, we are going to skip straight to the end boss."

"And who exactly are you?" Saphira moved a hand behind her back and motioned for them to move away. It was painfully obvious that she was trying her best to keep them safe. Charlotta moved forward holding her scythe in front of her, Aizawa moved up slightly keeping all the villains in line of sight. Thirteen seemed to take a stance but it was slightly confusing what she would do from this distance.

"It's not worth telling my name to people who won't be around long." His voice drawled out, there was something unhinged about his voice.

"And why are you so sure of that?" Aizawa intoned from the back of the group.

The man looked at the portal and motioned towards them, the inky blackness surrounded the students and they were disappearing one by one. His hand was clutching Mina's as the two of them went head first into a portal.
