"Can I be a hero, even without a quirk?" Izuku Midoriya asked as All Might walked towards the edge of the roof.
"...No. Without a quirk, It would be to dangerous." All Might responded. "If you want to be a hero, you could be a police officer. The get a lot of crap, but it's a good profession. Good bye." All Might jumped up the roof. Midoriya's eyes became dark as he went to the stairs.
"You want to be a hero so badly? You could take a swan dive of the roof & pray for a quirk in your next life." Bakugo said as he walked out of the classroom.
"Useless, helpless Izuku!" The classroom jeered. "Quirkless loser!"
"Guess they were right." Midoriya said to himself as he walked down the stairs to go home. "I am a useless, quirkless nobody." Midoriya walked home & greeted his mother.
"Hello honey. How was your day?" Inko Midoriya asked.
"It was fine mom." Izuku responded. Izuku walked to his room & looked long & hard at it. He had worshiped All Might, & for what. To be told by his idol to stop following his dreams, that was it. That was all he could take after the years of physical and psychological abuse from his classmates and Kacchan. Maybe Kacchan was right. This could be the end.
Izuku took a piece of paper & started writing. He wrote everything that he had wanted to do, everything he regretted, & the things on his bucket list that would remain undone. He grabbed his thirteenth hero analysis notebook & the piece of paper. Izuku looked at the clock. It said 9:30. He frowned & walked out of his room. His mother had left a bowl of food out on the table for him. He ate it. If he was going to die, his last meal might as well be something that she made. He left the note on the table & left the apartment.
Izuku walked to the building where his dreams had been crushed. He walked up each stair, not caring about what he was going to do. He made is way to the roof & looked over the edge. He stared down, looking at it as if it were an infinite abyss. He looked at his notebook & stood up on the rail. He jumped.
Izuku woke up staring at the sky. He felt a lot of pain in his right shoulder, but not much pain anywhere else. He laughed to himself. "I can't even commit suicide right, I am so useless." Izuku heard a noise. He slowly turned his head & saw a figure in the shadows. He seemed to have messy black hair & several bladed weapons. Izuku started towards him without fear. "Are you the hero killer: Stain?" Midoriya asked.
"I am, but how do you know me, & how did you find me?" He asked in a gravelly voice. Midoriya laughed a bit.
"I wasn't trying to find you, I was trying to die." He said with a little grin. Stain picked up a small burnt book that was on the ground & read through it.
"Did you take these notes? They are phenomenal. Why would you throw away your life when you can analyze almost every person & their quirk?"
"I tried because I'm quirkless." Izuku said as he started to frown.
"So? That doesn't mean that you aren't human." Izuku looked up with surprise. This person, the Hero Killer, said something that he needed to hear.
"I have lost hope in the heroes of our time. Can I join you in your conquest of teaching the heroes of our generation a lesson for their failures? I want heroes to be set on a new path of true acts of heroism. Will you let me?" Izuku said as he looked up at Stain, who was still reading through the hero analysis book. He put a hand on his chin & looked at Izuku Midoriya, the broken child with an amazing mind.
"Yes. You may join me on my conquest." Stain said. "I have looked for an apprentice who shared my ideals, I wished for them to be able to defeat me. I believe that you can be that successor."
"I have two conditions. The first is there will be no killing, only extensive beatings. The second is I wish to be trained by you. I am not the most physically strong." Izuku said. He tried to flex his right arm but found it was dislocated. Stain gritted his teeth.
"Fine, I will not kill any of them while I train you. But before the training can begin, you will need to relocate your shoulder." Midoriya gave him a shocked look.
"I didn't expect him to accept!" He thought. Izuku then took his shoulder & rammed it back into its socket as fast & as hard as he could. He grunted & panted afterwards, but most of the pain had subsided. Izuku moved his fingers & looked up to stain.
"Finally, you will need a villain name. If someone finds out your real name, then your family could be in danger." Midoriya went into hard thought & started to mutter.
"Deku, the name of someone who can't do anything."
"Deku. That will be my name." Midoriya said with hard eyes. Stain looked to him with content, licking his teeth.
"Well Deku," said Stain with a smile, "Welcome to your official villain training."
That is how Izuku Midoriya started his journey into villainy. Please write any questions or suggestions in the comments.
