Chapter: Satan

"Please remove any children under 13." The machine repeated. The students and teachers all looked around until someone spoke up.

"Does it mean me?" Eri asked in a soft voice. Mirio looked at the principal.

"Can I ask why Haro?" Nezu asked the machine.

"The next universe has scenes of a sensitive nature that may be too volatile for her to see," Haro replied sending Nezu a single word. The principal paled at that word and then nodded.

"If you would Mr. Togata?" Nezu waved the student over and showed him. Mirio grimaced and nodded.

"Eri, how about we go play hero for a bit? You can be Deku again."

"OKAY!" Mirio lead Eri out of the building as some of the students looked worried. A certain grape-haired boy was excited wondering if he'd get to see some of his female classmates in exposing situations.

"Well, I guess we should get this over with. Let me inform you all Hounddog is always willing to help if you are in trouble he is a licensed psychiatrist. Haro if you would?" Nezu nodded walking to his seat.


In another world, Ente Isla is a chain of islands that lies on the Ocean of Ignoria, consisting of one large central island with four smaller islands to the north, south, east, and west. It is laid out in the shape of a cross. The continent was in a time of peace until the Devil King Satan launched his invasion. With a massive army of demons, he sent his four generals to invade. Demon General Malacoda to the south, Demon General Adramelech to the north, Demon General Alciel to the east, and Demon General Lucifer to the west. Soon each island fell to the generals in quick succession. The Devil King would have won had it not been for the Hero Emilia and the Ente Islan Church. Slowly each general fell to their might one after another the islands were reclaimed and the last General Alciel retreated back to the demon castle.


"How does any of this connect to Midoriya sir?" Iida asked with stiff chopping motions.

"I'm honestly not sure. Isn't it exciting?" Nezuresponded.

"Perhaps it's a history lesson setting up the world? Perhaps something similar will happen during our time" Momo offered.

"I see, I wonder if Midoriya will be a descendent of this Emilia?" Iida pondered aloud.

"That's got to be it! Midoriya has to be her descendant he's just that good. Even as a mobster he still wanted to be a hero!" Kirishima bounced in his seat in excitement.


The final push into the demon territory was hash but eventually, the Hero and her knights made it to the castle. The trusted companions of the Hero fought the last general Alciel to a standstill while the Hero went to face King Satan himself. The fight was intense, the Hero and Satan were evenly matched until the Heroes companions cast a spell to slow time around Satan, With the opening she needed Emilia stuck Satan however he was able to avoid a mortal wound but in the process, his left horn was cut off shattering on the ground.

"I'm sorry my liege. They overcame my army and they got past me." Alciel spoke after he had stopped the spell trapping Satan.

"I never imagined that such a 'Hero' would push us to such a dire situation." Satan snarled.


"Come on Emilia you can beat him!" Mina cheered.

"Yeah! Girl power!" TGooru cheered along.


"It's only a matter of time until the castle is taken. We should retreat for now." Alciel advised. The Hero took advantage of that moment to try to land a mortal blow on The Devil King Only for him to vanish Alciel shortly following. Satan appeared in the sky above the castle with Alciel by his side.

"Hear me, Humans! I leave Ente Isla in your hands today! But head this! For when I return and I will crush you and conquer all of Ente Isla for good!" Satan spoke with such certainty as he opened a portal to escape this world so he and Alciel may regain their might and come back to full power.

Satan and Alciel awoke in an alleyway by a large building. Satan could still feel his power but it had diminished significantly after casting that spell. There was magic in the air but less than Ente Isla. Satan was taking in his surroundings and thinking 'It will take a while to recover it seems'.


"Oh, that's bull! You damn coward!" Denki snarled.

"What did you expect Pikachu? All villains are cowards. If I was the hero he wouldn't have gotten away, that extra was too slow." Bakugo bragged.

"That's an alleyway on my patrol route," Aizawa said as he realized what happened.

"So Satan came here? Don't worry he looks weak now I'm sure the little Listener can win." Present Mic commented.


"Sire you… Your body!" Alciel was frightened at what he saw. He could also still feel his magic but there was a repercussion it seemed Devil King Satan now looked like a young human.

"What the hell? How is this possible?" 'Maybe it's this world, maybe it forced me into this body' Satan turned to look at his trusted general to see if Alciel was affected. "It seems you were also affected Alciel." Alciel looked at his own body and screamed in horror.

"Maybe all life comes from humans?" Satan thought allowed. Before Alciel could speak they heard a scream. They looked up just in time to see a young man with dark green hair plummeting to land not far away with a sicking splat.


The students were all shocked at the scene. Some of the students rushed to the nearest bin and threw up. Bakugo and Izuku were more focused on the body. Dreed filled Bakugo's heart and his body felt clammy. Izuku was breathing heavily and was nearly panicking until all those nearest him such as Mei and All Might brought him back from the brink of a panic attack.

'No, no. you damn fool don't tell me… Please I didn't… Oh god.' Bakugo shook his head quickly wiping away a few tears that had formed and looked away.

"There's no way…" Kaminari said in a hoarse voice. "That wasn't… was it? Please tell me that wasn't who I think it is." No one responded and the deafening silence was chilling.

"What… WHAT THE HELL?!" Itsuka exploded in anger and sadness. "WHO! WHO THE HELL DID THAT TO MY IZUKU?!"

"Ms. Kendo. Please calm down." Nezu started.

"Calm down!? How can I calm down after seeing someone killed like that!?" Itsuka screamed.

"There's always more to the story," Nezu said clutching his phone with the message. "We won't know what happened until we see more." Itsuka marched over and sat closer to Izuku. If it was any other moment Setsuna would have teased her friend but knowing better she stayed her tongue.


"Shit Alciel we have to do something if this young man's body sees us we are in trouble!" Not thinking Satan used his magic to see if he could either assist or make the body vanish. The body was too damaged to repair but what Satan saw in the mind of this man had made him remember the hardships of his people this man had been through so much and it made Satan want to do something, anything to assist this man. 'I could do that. It would help me blend in better and I could learn about this world.' Satan had an idea but it was risky.


"Please help him," Uraraka whispered.


[5 Minutes ago]

He had just asked All Might the one question he had always wanted. Could a person with no quirk be a hero? He looked up to see smoke and an almost skeletal man standing in front of him coughing up blood.

"You're not… an imposter? What did you do with All Might!?"

"Young man calm down. I can assure you I am still All Might. This is just how I always look now." The skeletal man lifted his shirt to reveal a nasty scar.

"I was injured five years ago, losing most of my stomach and my respiratory system," he explained.

"Five years ago?… Could it have been Toxic-Chainsaw?… No, he wasn't strong enough. Must have been a villain not known to the public.


"No…" All Might choked out. He felt a gaze drilling into him and saw Aizawa glaring at him.


"HAHA! Kid, you sure do know your stuff. Toxic Chainsaw couldn't scratch me. The villain that did this was far worse and the fight was never made public. Now I hope you don't tell anyone." All Might, looked towards Izuku who nodded. "Good. Now to answer your question. 'Sigh' I'm sorry kid, being a hero is dangerous work. Without a quirk, you could easily die so no I don't think you can be a hero without a quirk. You should look at safer alternatives like police work. I must go. I'm sure if you knock on this door someone will hear and let you off this roof." All Might walked to the door and went inside leaving Izuku by himself.


"You idiot!" All the teachers yelled.

"You don't leave a citizen on a roof! And you certainly don't leave them there after shattering their dreams like that!" Recovery Girl started hitting All Might with her cane. Slowly the students started realizing what must have happened and they felt even worse now. While some agreed with the statement they all had a cold pit in their stomach. All those who were close to Izuku enveloped him in a large hug.

"Don't worry Izuku. I'd never think less of you if you were quirkless." Was the provelling statement they gave him. Bakugo on the other hand was having a small panic attack.


(Flashback to earlier that day)

"Oi, Deku I know a way you can be a hero." Katsuki waited for Izuku to look at him. "Just take a dive and pray you get a quirk in the next life! HAHAHAHA" Katsuki and his pals walked off laughing leaving Izuku alone.

(End of Flashback)


"I'LL FUCKING KILL YOU!" Itsuka tried to launch herself at Bakugo but Izuku grabbed her and held her tight.

"It's not worth it. I'm still here. I obviously didn't take that 'advice' ok." Izuku told her.

"What do you mean? That was the…" Itsuka's eyes widened followed by Setsuna's, and Mei's. "He didn't… I know you are a late bloomer but… oh my god." As that was going on Bakugo felt a hand on his shoulder. His homeroom teacher was looking at him intently and all he could do was look away in shame.

"*sigh* We're going to have a talk later understood?" Aizawa asked and all Bakugo could do was nod.


His own Idol the man who said anyone could be a hero told him he could never be a hero. 'I guess it was just a stupid dream after all.' All the work he did had amounted to nothing at all his hero notebooks meant nothing. This world was so cruel to those without quirks of course All Might would say that. 'He's just like the rest.'

Izuku walked to the railing of the building. "You might be right kachan." He stepped over the railing and stood on the edge. 'Sorry, mom it looks like I'm nothing but a useless Deku after all you would be far better off without me. Sorry, Chi-chan I guess I wasn't as strong as you thought I was, hopefully, they can find a replacement for me soon. I don't want you working there alone.' He breathed in and let himself fall. As his life flashed before his eyes he realized he didn't want to die. 'NO NO NO!' "AHHHHH!". The next thing he knew was unimaginable pain he wanted to cry but couldn't get the sound out of his throat. As the darkness closed in there was a warmth followed by a blinding light. As the light faded he found himself in a dark room where a man with black hair and red eyes sat in an armchair.

"Please sit Izuku Midoriya. There's much for us to discuss." the man waved his hand revealing another chair.

"Am I dead? Wh...who are you? What do...do you want?" This was all surreal.

"Yes in a way you are dead but in another, you aren't. Me? I'm The Devil King Satan and I've come up with a deal." The man's red eyes glowed as he smiled after saying that.


Class B looked towards Ibara, surprisingly all she did was make a quick sign and refused to say a word. None of them blamed her after watching someone as bright as Izuku midoriya take his own life they too would refuse to say anything bad about him, even Monoma.


"What kind of deal?" Izuku was hesitant but he sat in the chair. 'There's no way he can heal me my body's too broken'

"You are correct with my powers, no I can not heal you. That is where this deal comes in. You see I'm not from your world, I used most of my power to escape my own. I need help understanding this world and you wish to be a hero. So here is my deal. I do know not if I can return to Ente Isla so I wish to stay here until I know for certain. If I can then I will remember this as it will affect you as well. With my power, I can house your soul with mine and change my appearance to look like you. You will not be trapped in your body; you will have just as much control as I over the body so that's why I want us to come to an understanding. With my powers, you can be a hero. Do you accept?" The Devil king brought his hand out to be shaken.

"You will not be trapped in your body; you will have just as much control as I over the body so that's why I want us to come to an understanding. With my powers, you can be a hero. Do you accept?" The Devil king brought his hand out to be shaken.

The thought of sharing a body with the Devil King was frightening but if he didn't he would die. 'Would they still consider me a hero if I looked like that?' Izuku thought looking at Satan's horns, red eyes, and claws. He started to mutter up a storm about the pros and cons of the deal but he came to an eerie thought.

"Yo..you said if you can get back it would affect me as well correct? Why is that?" Izuku was cautious he had read stories where such deals were merely tricks.

"Ah, not eager to rush into danger without knowing the facts hmm. Alright. The spell I will use might fuse our souls together one day could be a few days, a few months, or even a year. It all depends on how accepting you are of the other person aka me." Satan waved his hand as he spoke.

"W...What!? But….but….what would happen to me then when they fuse?" Izuku was terrified he believed he could lose himself.

"Not sure to be honest." Satan sat forward thinking.

"If you aren't sure why offer this deal you could lose yourself?" 'Or myself' Izuku didn't want to die and this seemed just like a prolonged death sentence.


"As much as I would like to reprimand you for even thinking about taking that deal Midoriya I can not bring myself to do so," Iida informed his friend.

"It's alright Iida. Honestly, I'm not sure what my answer would be anyways." Izuku chuckled.


"It was on a whim. You reminded me of a demon boy I knew. You see we demons were treated like monsters like we didn't belong even though we shared our world with humans since the beginning of time. He thought he could befriend humans but they scorned him, mocked him, and even attacked him. You reminded me of him because like you and your... limitations he never gave up but in the end, it didn't work." Satan's gaze turned down and for a while, all was quiet until he spoke again. "My best guess is we will keep both of our memories while certain powerful traits would take over like say my confidence would overrule your anxiety. There may be a way to reverse it but I do not know one and that is why I said this would affect you should I return as you may have to return with me. If only I had more magic I might have been able to save you fully. So what do you say?" Reaching his hand out once more.


The students and teachers all wondered what they would do in that situation. At first, they just saw Satan as a villain but that wasn't true. It seemed as though he and his kind suffered greatly on Ente Isla. While they did not approve of his methods they at least made more sense. But to potentially become that world's greatest villain was a hefty cost.


'If I don't I'm dead.' "Deal!" Izuku grasped the outstretched hand and was blinded by the light. The next thing he knew he was standing over a charred smug on the ground. He felt taller not by much though.

"Sire? Is that you? What happened?" A voice he recognized asked in fear and astonishment.

"Indeed Alciel. I used a spell to join my soul with this childs. This world we are in is quite interesting." Izuku spoke with Satan's voice. 'Oh god, this is so strange!' 'Indeed Izuku we are one but separate for now. Heh, I doubt you want to tell people you're speaking to Satan so just call me Sadao.' 'Alright'


"Huh kinda reminds me of that pre-quirk era show I watched as a kid. What was it called? Rudy? I can't really remember." Mina said. "Anyway the headmaster of their school was cursed to reincarnate within another person each time he died. It was an ok show, some seasons were not good but overall it ended up better than I thought it would."


"What do you mean?" Alciel asked with a hint of curiosity.

"Walk with me. We have to get you official paper's in case we get stopped by the authorities here. I'll explain while we walk." Sadio said while leaving the alley. Sadio spoke of quirks and how society changed to include them causing the rise of heroes and villains. He spoke of Izuku and his hope to become a hero and how his dreams were shattered when his idol told him he never could since he was what was called quirkless. He explained the deal they made and what would be happening.

"HAHAHA! If only Emilia could hear the great Devil King speaking about becoming a hero! But this leads me to ask what of me? What should I do." Alciel now legally Shirō Ashiya asked.

'What should we do? I was thinking of using what little magic I have left in convincing your mother to let him stay.' Sadio mentally asked Izuku. 'That should work, she's been having trouble since… she got sick. She's better now but…' Izuku trailed off and Sadao just nodded.


"Oh, god damnit," Bakugo muttered. If he wasn't feeling bad now he felt like a freaking monster now.

"Oh god," Izuku felt his mouth dry up, his other self jumped knowing his mom was sick. That likely would have been the final nail for her. "I'm going to call her today when I get a chance."

"Don't worry, we'll be here for you," Mei told him and the others nodded.


"Well, Alciel I would like you to help out around the… my house. It seems...my mother got sick and hasn't been the same since." This was all still rather odd to Sadao as well.

"Of course Sire! It would be my pleasure to assist your honored mother!" Alciel was taking this well. The Devil King was now this Izuku Midoriya which meant it was now his job to protect his lieges mother. They continued their walk home until they heard explosions off in the distance.

"Sire is the city under attack?!" Alciel was prepared to fight to the death for Izuku/Satan.

"No it's a villain attack lets go, this will be a good chance to get notes and for you to learn what this world is like." Izuku was in control now. With Sadao's promise, he was feeling more confident now. They rush to the shopping center where the explosions are coming from just to see something that turns Izuku's blood to ice. "The...the sludge villain."

"What was that sire?" Alciel leaned down to hear him better over this crowd.

"It's all my fault if I hadn't grabbed onto All Might he wouldn't be free." Izuku was trembling and berating himself. Sadao was about to take over to keep Izuku calm but was stopped. "No...Kacchan. Why why isn't anyone helping that monster has Kacchan?" All around them people were asking why the heroes were doing nothing while the heroes made excuses about how their quirks wouldn't work. A split second later and Izuku's head felt like someone was driving nails through it. "AHHHHHHHHHHH!" He dropped to the ground clutching his head. People rushed to him to see what was wrong one of the heroes was calling for paramedics. What felt like an eternity later the pain was gone. Izuku felt lighter, his head was a little heavier. Around him, a dark miasma filled his body making him stronger. He looked around to see no one had helped yet. Without thinking, Izuku rushed forward out of the crowd with people telling him it was dangerous but he didn't listen. He threw a rock from the ground at the sludge's eye.


"Well, that dark stuff doesn't look good." Denki joked.

"But what exactly was that stuff?" Iida wondered aloud.

"Haro, a Demon of Ente Isla gains power by feeding off negative emotions like fear and despair from sentient beings in his surroundings," Haro explained.

"Well, that's terrifying." Denki shuddered.

"So during a villain attack, Midoriya could become even more powerful when dealing with citizens." Vlad theorized.

"He could also use the villain's own fear against them." Aizawa pointed out.


"You look familiar oh well if you want to die so be IT!" the villain swung a tendril of sludge at him. Izuku barely dodged falling to the ground but he pushed himself up and got to Bakugou. He grabbed one of his arms yanking the ash blonde out of the villain.

"ARGH, my hostage! You'll die, you damn insect!" The sludge attacked again but was blown away by a punch.

"HA HA SORRY I'M LATE YOUNG MAN LET ME HANDLE IT NOW! FOR I AM HERE!" The booming voice of All Might boasted as he delivered another punch causing it to rain. After everything was over the media swarmed All Might and the Paramedics took away an unconscious Bakugou. The rest of the heroes had cornered Izuku and were telling him how dangerous his stunt was.

"Sorry, my body just moved on its own." Izuku bowed and apologized.

"Kid are you sure you're ok? You were screaming earlier… UH, GUYS LOOK!" Death Arms pointed at Izuku's head. Izuku was confused as to why he was pointing at his head. He started moving his hands on his head to see if he was bleeding and he stopped when he found a broken stump on one side and a larger pointed bit on the other. He quickly pulled out his phone with the front-facing camera and his jaw dropped.

"I HAVE HORNS?!" Izuku shouted in fear. 'HUH BUT HOW?! I don't have enough magic to transform?' Sadao was just as confused.

"YOU DIDN'T HAVE THEM BEFORE?!" All of the other heroes around him asked. Izuku just shook his head.

"How's that possible mutation quirks are usually known at birth either by signs or their mutation already showing?" Mt Lady was thinking out loud.

"Maybe it's a transformation quirk? Can you try concentrating to make them go away, kid?" Kamui Woods inquired. Izuku did just that but no matter how hard he thought nothing happened.

"Sorry, nothing's happening."

"It's fine kid. How about you follow me back to my office? It's just a few blocks away and I can get a doctor to give you a check-up." Death Arms offered.

"Oh sorry, sir I work today I'm helping my coworker learn how to use the ice cream machine. I can't be late." Izuku apologized before running off.

'Smooth. No idea what a doctor check-up would show since we are a demon.' Sadao thought. 'Yeah there's that but I wasn't lying. I really do work today.' Izuku shot back.


"I wonder where he works?" Denki asked.

"Either an Ice Cream parlor or fast food, they're some of the few places willong to hire middle schoolers as long as the school and parents allow it." Uraraka chimed in.


"Sire? Where are we going?" Alciel asked. Izuku immediately facepalmed 'With all that happened I forgot all about him.'

"Well I work in 40 minutes so I have to get there. Hmm, there's a library down the street. How about I meet you there after work? You can study history and stuff so you'll know more of this world." Izuku offered some money for a card for Alciel.

"You are most wise sire. I shall do just that." Alciel bowed. Izuku pointed to the library and told him his shift ended at 9 and went on his way. As he was opening the door to MgRonalds he thought 'I can't wait to see Chi-Chan... wait oh shit my horns! I need A new hat! Dammit, that's going to cost money.' the manager looked up from the register.

"Hello, sir what can I get for yooo… Izuku? You know we don't allow costumes, take those horns off and get ready." She spoke with a friendly yet stern commanding voice.

"Uh about that. It seems that my quirk finally showed up. These horns are real." Izuku tugged on the non-broken one to emphasize the point. The screen faded black.


"Well I'm not sure about all of you but I need some air." Present Mic stood up and left. A handful of students followed.
