"Alright, how can I turn Issei back into a human?" Izuku asked the Vestige of One For All as he looked to brainstorm some ideas.
"I don't think none of our quirks can help you here." The 4th user said
"yea, the only one that comes close is New Order." All Might said
"she used Magic to turn him into a devil, so maybe I can use magic to turn him back into a human."
"You think Buu's powers can help you here?" All Might Asked
"I don't know what all he can do." He wasn't exactly training with Buu's magic and stuff. "I'll need to go through his memories and see what he can do."
"maybe I can help you." A voice called out in Izuku's mind and it wasn't One For All.
"Who are you?" Izuku asked
"My name is Dai Kaioshin, I'm a Kai that Majin Buu absorbed. I can turn your friend back into a human if you let me."
Time Skip
"Thanks for coming over." Izuku asked Issei to come over saying that it was important.
"No problem, wow this is a cool place," Issei said as he took in his surroundings. This was the first time he had ever been inside a penthouse.
"I know what happened to you." Izuku stated getting straight to business.
"What do you mean, you know what happened to me last night?"
Ya, you were attacked by a fallen angel." And just like Izuku expected, Issei had a confused look on his face so Izuku decided to explain everything.
"Okay, listen. You know how I told you about that dream I had?" Issei nodded his head remembering Izuku's story.
"Well, it wasn't a dream. You had a girlfriend who went by the name of Yuuma Amano, but her real name was Raynare and she was a fallen angel sent to kill you because you possessed a sacred gear." He explained.
"wow, you know that actually makes a lot of sense. She was going on and on about how I was a threat and stuff. "Wait why don't I remember her then?"
"Because after I threatened her, she erased everyone's memories of her, including yours. I put something on her so she won't kill any innocent people."
Issei relaxed on the couch and began absorbing the information.
"Please explain to me what happened yesterday. Who was that woman?"
"That was one of her comrades who killed you. Sorry, I wasn't there."
"Wait, I died? How am I still alive?"
"Rias Gremory reincarnated you and now you're a devil and you will serve her." Izuku said while cringing at the last part.
"She knew what was going on, right? That's why she was so interested in your dream yesterday," Issei said as all the pieces started to fall into place.
"Tell me, now that you're a devil do you feel any different?" Izuku asked
"Hmm, well I can hear a lot better."
"That boy has a unbelievable power inside of him." Dai Kaioshin said
"I'm ready when you are, just tell me what to do."
"Let me take control of your body."
"Uhm, how?" As soon as Izuku said that his eyes closed and when they opened up Dai Kaioshin was in control.
"Don't worry; I will give you your body back once I am finished. Watch closely Izuku, you can copy abilities that you see once."
Izuku watched with rapt attention from within his mind'scape
Kaioshin placed his hand on top of Issei's head and he began to glow. "I'm going to turn you back to normal, don't worry. You won't have to work for anyone." As he said this, eight pawn pieces fell out of his body.
"Hmm, so that's what evil pieces look like." Izuku commented.
"What are those?" Issei asked
"This is what the girl used to reincarnate you. I turned you back into a human. However, you can still use some of your devil abilities and techniques. You won't be able to use all of them though since you're now human."
"So what can I do?" Issei asked.
"How's your hearing? Are you still able to hear things from far distances?" You should be able to because that's not a physical upgrade.
Issei tried to listen for anything and sure enough he heard some people talking somewhere in the building.
"Yeah, I can still hear pretty well."
"That's what I expected," he said. "Now let me see something." Kaioshin placed his hand on top of Issei's head as he wants to release his sacred gear.
"I want to see what your sacred gear is. How much of a threat do you pose?"After he said that, Issei experienced a slight increase in power as a red gauntlet appeared on his hand before expanding and covering his entire arm.
"Wow this looks pretty cool." Issei exclaimed.
"I can sense someone inside of it." Kaioshin said.
"What, really?"
"Yeah, they might be sleep or something."
"Hey, there's a smartphone in my pocket; can you please take a picture of the gauntlet?"
Kaioshin listened to Izuku and took out a cell phone. Thanks to Buu's magic Izuku was able to recreate some of the technology in his world. He should start a tech company, but people will have questions about how it was made.
"What kinda phone is that? I mean there's no buttons on it." Issei asked as he's never seen such a high tech phone before.
"It's a smartphone." Kaioshin answered while taking a picture of Issei's gauntlet.
"I'm sure that Rias Gremory will try and talk to you tomorrow. You should give her back those chess pieces. Oh, and try and talk to that being in the gauntlet."
Issei had left, but he didn't comment on how his friends demeanor had changed.
"Okay, can I have my body back." Izuku asked. After Izuku asked that question he was in control again.
Hey, Ninth, you should come to the Vestige World; there's something we need to discuss. The first user of One For All said.
————
Izuku lay down on his bed and entered the vestige world of One For All. Immediately noticing that it looked different, he found himself surrounded by green grass, a purple sky, and a whole lot of moons.
"Huh, this place looks... different," Izuku said as he took in his surroundings.
"Yea, that's all thanks to this guy." All Might said gesturing to a pink man who Izuku has never seen before.
"Are you the person who took over my body? Who are you?" Izuku asked.
"I'm a Kaioshin," he said, "and I was absorbed by Majin Buu many, many years ago." He pointed towards the cocoon where Buu slept. "I have many names; the Great Lord of Lords, Supreme Kai, and Dai Kaioshin. Any name is fine with me, I don't really care."
"If you were absorbed by Buu, then how are you here?" Izuku asked.
"Because Buu is sealed inside of you and I'm sealed inside of him," Kaioshin explained, he then pointed at the other vestiges. "Just like how they can manifest inside of your head, so can I."
Izuku just nodded dumbly. He felt a strange presence coming from him it was an aura of love, safety, and politeness.
"So how long can you stay here? I can teach you some abilities."
Izuku became serious after that. "I got control over the vestige world. I can almost stay here for as long as I want now."
"Good, come with me; there are a few things I'd like to teach you before you wake up."
———
the next day
'Huh, he's not here today.' Issei thought after entering the classroom and not seeing Izuku.
"Wow, Midroriya is never absent." A random student said
"I hope he's okay. Izuku helps me with my schoolwork," a female said.
after school was over all of the students were hanging around. Issei was about to go home until he was stopped by Kiba.
"Hey, Issei mind if we talk for a second? My president would like to see you." Kiba informed him while also ignoring the girls squealing when he enter the classroom.
"huh, ya sure." Issei said not really caring
Occult Research club room
"Hello, Issei," Rias said. "I bet you're wondering what happened to you yesterday."
"no, not really. Izuku already explained what happened to me." Issei said shocking her peerage
"What did he tell you?" Rias asked.
"Well, he told me that the girl who killed me was a fallen angel, that you are a devil, and that you had reincarnated me into a devil after she killed me." Rias was shocked as Izuku basically revealed everything about them.
"Oh, he also wanted me to give you these. He said that he was going to turn me back into a human, and then these chess pieces just fell out of me." Issei said while handing Rias eight Pawn pieces. Rias's heart almost stopped beating. No one said anything; they were all too shocked by what they had heard.
'He did it, he actually did it.' She thought with a bit of anger and curiosity. Her curiosity overshadowed her anger though.
"where is he?" Rias asked with a dark tone.
"I don't know, he didn't come to school today." Issei said a bit scared after hearing her tone.
Rias looked into Issei's eyes, her blue eyes staring into his, trying to find a hint of deceit.
"Issei, listen," Rias said, "My peerage has things to do today. You're not going to talk about this to anyone." She could just erase his memories, but she doesn't know what Midroriya can do. He could probably restore his memories for him. She doesn't know the full extent of his powers and that thought just infuriates her.
Before Issei was out the door he turned
around to say something.
"Thank you for saving me," Issei said gratefully. "I would have been dead if you hadn't revived me." With that, he left the club room.
"Do you want me to go find Izuku?" Koneko asked after Issei left.
"No, he'll be back eventually." She continued "I need to make a phone call" Rias walked out of the room followed by Akeno.
After Rias stepped outside she used her magic to get in touch with her friend. "Sona, we need to talk." Sona knew it was something serious by Rias tone.
———
Just like the Occult Research club the student body council were also devils. They are ran by Sona Sitri. Sona is very strict and intelligent. She does not take anything lightly whether that's dealing with the school or devil matters. She is a bespectacled young woman with a slim figure, black hair styled in a short bob cut and violet eyes.
"By your tone of voice, I can tell it's something serious," Sona said as she, Akeno, and Rias were in the Student Council's Office.
"You have access to all of the students information, I need information on someone," Rias said.
"Who do you need information on." Sona said while adjusting her glasses.
"We want information about the new student, Izuku Midroriya." Akeno informed her.
"Seems a bit random, any reason? He seems like a nice guy although people say he's a bit shy and timid."
Rias said, "I believe that's just an act he puts on."
"What makes you say that?" Sona asked.
"He knows about the supernatural. When I tried to convince him to join my peerage, he said my pitch sounded awful."
"You're not a good negotiator, are you? You never had to convince anyone to join your peerage before."
"My pitch was solid. He just wasn't interested in the things that come with being a Devil. Anybody else would have jumped at the opportunity." Rias said.
"Does he have any special powers?" Sona asked.
"Yes, and that is what worries me because we don't know what all he can do." Rias answered.
"What do you have on him so far?"
"Koneko saw him fight a fallen angel and he won easily with only seventeen percent of his full power. The fallen angel begged for her life and Izuku ended up taking her somewhere. Me and Akeno went to his house, but he wouldn't let us in. We found out that he lives in a Penthouse." Rias informed her.
"Hmmm, so if he lives in a penthouse, his parents must be rich. But I'm more interested in knowing about his powers."
"Koneko followed him after school and he came into contact with another fallen angel. We saw what he could do firsthand. First, he's got super strength and he can emit some black tendrils from his body."
"Super strength and black tendrils, is there anything else?"
"Listen, if you're going to get close to him, don't let him touch you. He can disassemble and reassemble anything he touches."
Sona widened her eyes after hearing that. "What kind of sacred gear is that? He can basically kill you with a touch."
"That's not all, he also used an ability on the fallen angel who was about to kill Issei. I don't know what he did, but he said that he ensured she wouldn't be able to kill him."
"So what do you think he did to her?" Sona asked.
"I don't know, but he claimed it was his favorite ability."
"I think he took away her abilities. Why else would she not want to kill her target?" Sona theorized.
"Hmm, that's a possibility," Rias said as she thought about her theory.
"Rias, I think you forgot about what he did to that Fallen." Akeno said.
Rias was confused for a second before it hit her. "Oh, I almost forgot. We saw Izuku shoot a pink magic beam at the Fallen Angel and it turned him into a cookie."
Sona blinked a few times trying to process what her friend just said. "What happened to the cookie?" Sona asked hesitantly as she was afraid of the answer.
"We don't know what happened to the cookie, because he took it with him." Rias answered.
"Now, for the real reason I'm here." Rias said which grabbed Sona's attention.
"Personally I wouldn't have came here if he just had those abilities, but he did something that should be impossible."
"What did he do?" Sona asked fearing the answer.
"After Issei was killed by a fallen angel, I used all eight of my pawn pieces to reincarnate him into my peerage," Rias said as she took out her chess pieces and placed them on the desk. "Izuku turned him back into a human."
Sona was shocked by what she just heard. "He's able to turn reincarnated devils back into their original races. Rias, I think this is something that your brother should handle." Sona said that last part sternly.
"No, he doesn't need to get involved," Rias stated as this was her territory and she didn't want her brother's help.
This is a serious matter; he could join up with a faction and just wipe us out. In the worst-case scenario, we could become extinct.
"Don't worry, he won't team up with the Fallen Angels," Rias said.
"And how do you know that?" Sona asked.
"Maybe some fallen angel can convince him to join them. Wait, who else knows about this?"
"The only ones who know are my peerage and probably Issei," Rias said.
"If you're not going to tell your brother, at the very least keep it a secret. If the reincarnated devils find out, they might seek him out in order to turn them back to normal."
"That could be a problem," Rias said.
"Yes, exactly. Thank you for informing me of this. I will investigate him right away."
Rias left as she knows that she can count on Sona to find information on Izuku. Right now she needs to convince Issei to join her peerage.
———
Izuku woke up after being unconscious for a day. Thanks to the supreme Kai the vestige world of one for all isn't just some room with chairs. It's now a field with green grass, a purple sky and a whole lot of moons.
Izuku learned many techniques from Kaioshin. How to sense the life energy of other people, how to materialize things from thin air, how to teleport, communicate with people telepathically and he also learned more about Majin Buu and the terror he caused across the universe.
For some reason, Izuku could never look too far into Buu's memories; as if something was blocking it. When he tried to see what happened after Buu got eaten by a gray version of himself, he immediately got a nosebleed. However, the last memory of Buu fighting he was able to see was him versus a kid version of himself. Kaioshin told him that that's the original form of Buu, who is pure evil and wants nothing but destruction. He also told him that he has the other half of his God Ki.
Kaioshin used his magic allowing Izuku to see what had happened during Buu's rampage. He saw what the creator of Buu was capable of doing with his magic. He saw him controlling people by manipulating the evil within their hearts. Izuku had no use for that ability as he would never want to control people, but that doesn't mean he didn't see how he did it.
When Izuku woke up he took out a notebook and put "Supernatural abilities" he was planning on analyzing every ability he comes across in this world. He however had a separate book for his own abilities.
———
Izuku was currently trying to avoid Rias Gremory, after what he had done to Issei. He got to school early and was about to head towards the library when he was stopped by Sona Sitri.
"Hello, you're Izuku Midoriya, aren't you?" Sona said.
"Yes, I am Izuku Midoriya. It's a pleasure to meet you."
"You probably already know me, but I'm the student body council president, Souna Shitori."
"Yeah, I've heard so much about you," Izuku replied, though he had never met her before, but students talked a lot.
"Well, I need your help. The Student Body Council is behind on some paperwork and some of its members did not come to school today. Would you mind helping us out?"
"Sure, I don't mind helping, but I can't be late for my first class," Izuku stated.
"Oh, that won't be a problem. By any chance you're late I can excuse it."
After Izuku heard her he decided to help her out with whatever she needed.
Student council office
Sona opened the door to the student council office. When Izuku entered, he saw a blonde-haired boy doing a lot of paperwork.
"This is Saji, and he needs your help with some of his paperwork."
"Okay, but what am I supposed to be doing exactly?" Izuku asked, not knowing how they operated.
"Don't worry, Saji will show you how to do it. Saji, can we talk for a minute, it's important." Saji had got up and followed Sona outside. "Excuse me for a second Izuku." Sona said.
"No problem," Izuku said before Sona closed the door.
"What's going on? Why do you want me to work with him?" Saji asked, as Sona hadn't told him about her investigation on Izuku.
"I am investigating him; I could not find anything on him. So I need you to be friendly and see if he will reveal anything about himself."
"Is there something special about him?" Saji asked curious about the boy.
"It's best if you don't know." Sona replied
Three hour time skip
Izuku and Saji were both doing paperwork. They had been at it for the past three hours. Izuku had missed most of his classes, but he didn't mind since he wasn't going to fail. He was a top student after all. Saji kept asking Izuku about his life before he came to Kuoh, and Izuku did his best to not give him too many details. Saji picked up on how vague Izuku was being, however. Sona had left, saying that she needed to do her own paperwork, but in reality, she just wanted Izuku and Saji to bond. She was trying to use her pawn to get information about Izuku.
———
After their test was over Sona and Saji had a talk.
"So what did you learn about him?" Sona asked.
"Nothing," he replied, shaking his head. "He was being very vague about everything I asked him. However, I did ask him about his parents." Saji looked down after saying the last part.
"And what about his parents?"
"He said they died. It doesn't seem like there's anything special about him.
"Given what Rias told me, he is capable of killing a fallen angel. Rias even asked him to join her peerage, but he refused. He also did something that put us both on guard, but that's going to remain between us for now."
"What did he do?" Saji asked a bit curious.
"His powers could become a problem if he decided to turn on us devils. He has the potential to make us devils go extinct." A chill went down Saji's spine after hearing that.
———
Classes had ended and everybody was socializing with each other. Izuku had already left to go home while Issei was getting ready to leave until he was stopped by Kiba Again.
"Hey, Issei, my president would like to see you again," Kiba said, ignoring the female members of the class once more.
"Yeah, okay, I'm coming," Issei said as he followed behind Kiba.
"Welcome back, Issei. Tell me, what do you know about us?" Rias said after Issei entered the club room.
"well, I know that you're a devil, but that's about it. Izuku didn't explain that much to me."
"Well, let me introduce you to my peerage members." Rias then went around the room introducing everyone by name then their pieces.
"So, Issei I have a important question. Would you like to join my peerage?" Rias asked after she explained everything to him.
"Hmmm... I don't know I want to think about that for a while."
"That's fine take as much time as you want. This is a very tough decision." Rias said as she really wants Issei to join her peerage.
"Wait, I have a question. Did you ask Izuku to join your peerage?"
"Yes, I asked him to join, but he declined." Rias stated.
"Okay, thank you" Issei said before leaving.
"Do you think he will join us?" Akeno asked
"I hope so," Rias stated.
———
Issei had walked to school the day after he met Rias. His world was basically turned upside down. The supernatural exist devils, and fallen angels are real. Not paying attention to where he was going he accidentally knocked over a girl.
Issei had a perverted look on his face when he saw the girls underwear.
"Hey, are you okay?" Issei asked trying to help the girl up. She was wearing a dark teal nun outfit with light blue accent. When the girl got to her feet her white veil over her head came off revealing her face. She had blonde hair, green eyes, and a very innocent look. Thinking quickly Issei went to catch the veil before it blows away.
"This girl is just my type," Issei thought after handing her the veil.
"I'm sorry, but I'm a little bit lost; do you think you could help me out?" the girl asked with a kind smile.
"Sure, where are you trying to go?"
"Well I was assigned to the church in this town."
"Oh, I know where the church is at. I can take you there if you want." Issei said
"Thank you that will be great. I'm Asia Argento."
"I'm Issei Hyoudou."
Issei was escorting Asia when they heard a kid crying. Asia ran over to the kid, who had fallen and gotten a scar on his knee. Asia healed him, revealing her Sacred Gear to Issei.
"You must be surprised." Asia said
"No, I've seen some weird stuff these past few days." If he would've met her about a week ago then he would've been shocked about her ability.
"But that's a crazy ability you got."
"Yea, it was a gift from god." Asia had stopped talking when they made it to the church.
"Thank you so much. I never would've found it without you. Do you want to come in for some tea, as a thank you?"
"No, sorry but I have to get to school."
"Well, you can come by anytime," Asia said.
"Yea, I will come and see you when I have free time." Issei said before leaving.
———
Once again, Izuku had arrived at school early. He wanted to avoid a certain redhead. As he walked down the hallways, he heard a voice calling out from behind him.
"Hello, Izuku," said Rias Gremory, glaring at him. He quickly looked around, but to his shock, nobody else was in the hallway. (Nobody was there to witness him getting murdered.)
"What do you want?" Izuku asked.
"how did you do it?" Rias asked.
"I can do a lot of stuff, I'm not telling you my secrets."
"you might not like how we operate, but we need to Reincarnate humans to keep from going extinct."
"I don't have a problem with you guys Reincarnating humans, however I do have a problem with it not being a choice." He continued "for example Fallen angels have humans working for them, but they actually have a choice." After Izuku said that Rias's tone changed.
"You're working with Fallen angels?" Rias asked with narrowed eyes.
"What? No of course not, I just used them as a example." Izuku said while waving his hands in his face.
"so how do you know they got humans working for them?"
"Oh, I hear a lot of stuff, I'm pretty sure angels also recruit humans too, but again it's a choice."
"Well, you should know that I offered Issei a chance to join my peerage."
"So What was his answer?" Izuku asked.
"He said he needed to think about it. If he does decide to join us you're going to stay out of it and not turn him back into a human." Rias said.
"As long as he's happy and he chooses to join you, I wouldn't need to get involved."
"You don't need to get involved at all this isn't any of your business."
"My mentor once told me that meddling when you don't have to is what makes a person a hero." Izuku stated
"But your not a hero." Rias felt danger wash over her when she said that.
Izuku just took a deep breath
"I'm going to class." Izuku said he was about to turn and walk away, but he had something to say. "You should know that I'll be teaching Issei how to use his sacred gear."
"Really, I can help him unlock it." Rias said
"No, It's already been unlocked."
"Really, what is it." Rias asked.
"You tell me." Izuku said as he took out his phone.
"That's a weird device you have there," Rias said, looking at Izuku's high-tech phone.
"It's just a phone," he told her. "Here, I took a picture of Issei's Sacred Gear for you. Tell me what it is."
Rias looked at the picture on the phone and her eyes widened.
"Do you know what it is?" Izuku asked after seeing her reaction.
"That sacred gear is called the Boosted Gear. It's a Longinus, and it contains one of the Heavenly Dragons that can kill even God."
"He shouldn't have been able to unlock such a powerful sacred gear. You had something to do with it, didn't you?" Rias asked.
Izuku didn't know what to say, he was never good at coming up with a lie on the spot.
"What did you do?" Rias asked and Izuku was cornered. The good thing is he can tell her part of the truth without revealing the whole truth.
"I know how to release someone's hidden potential and powers that are dormant; I can awaken them."
Rias's jaw dropped and her eyes widened; a part of her didn't believe him, but the proof was right in front of her. Issei wouldn't have unlocked his Sacred Gear without some kind of help.
Seeing her stunned face, Izuku decided to slip away. "I'm going to class," he said as he walked away from her.
