Long ago, a glowing baby was born in China. Soon after, strange powers started to appear everywhere. These new powers were called Quirks and they represented a new age of human evolution. With the emergence of Quirks, there came people who abused them and with the appearance of villains, a new career that had only been in comic books came forward:

Heroes.

Meet Sirius Blakefield, a seven-year-old hero-in-the-making. He is the grandson of Lupin Blakefield, son of Romulus and Meiko Blakefield, and has four brothers older than himself. This is the story of how he became friends with two of the greatest students ever!

Sirius groaned in pain as he was hit in the stomach multiple times, arms restrained by the assailant's lackeys so he was unable to defend himself.

If you were wondering how he got into this mess, he'd say it started about ten minutes ago, when he'd seen three boys at Nabu Elementary. Sirius immediately recognized two from the year above his: fraternal twins known as "Duo", an alias that sent shivers through the entire elementary school. They and their leader were deeply prejudiced, especially against students who didn't look like normal humans, so Sirius' dog features had earned their torment from day one.

Their bullying towards him was bad enough, but he especially hated seeing them make others suffer. So, when he noticed them teasing another, a purple-haired boy similarly-aged to himself who looked overwhelmed, Sirius snapped. Running straight towards them, he tackled their leader and landed a hit on his face, yelling: "Pick on someone your own age, cowards!" He only knew the other boy's age due to the teacher's introductions.

He supposed he could have handled it better; could have jumped them at the back of the school or something, but he wanted to teach them a lesson. Now jerked back and pinned to the ground by Duo, it seemed he'd been overly ambitious. Sirius gritted his teeth and spat at the floor. Trying to escape while he still had the mettle, he surged up in a burst of superior strength and pushed past his enemies, forgetting about the purple-haired boy.

Sirius only got as far as a minute's distance before his stamina ran out and he fell to his knees, panting. His enhanced hearing picked up the bullies' rapid approach, but he couldn't find the power to move before he was picked up by the collar. His weak attempt to hit the leader's arm failed; Sirius hadn't mastered his fighting capabilities yet.

The leader threw him to the ground and a pain-filled whimper escaped Sirius' lips. When he tried to crawl away, he was kicked in the jaw for his efforts. His lip busted, but he ignored the pain as best he could. That was all he could do to resist.

"You two!" the leader commanded Duo. "Pick him up and hold his arms."

The pair did as they were told as their boss stood in front of Sirius. Looking directly at the other boy, Sirius spat in his face. The leader's expression twisted into a snarl.

"You're weak," he hissed in Sirius' ear, punching him in the gut twice. Groaning in pain, Sirius didn't have the energy to do anything, even as the onslaught continued. As his sight started fading out, he distantly heard a young male voice speak. Then there was nothing but the darkness.

Sirius later awoke in what appeared to be the nurse's office and promptly threw up in the bedside bucket. His throat burned from the retching and his head pounded with a headache.

"Oh, you're awake."

Sirius turned to see an unfamiliar boy at the foot of his bed. Blinking multiple times, Sirius ran his gaze over the latter's body. There wasn't a scratch on him, so why was he here?

The boy continued: "You saved me before, so I wanted to thank you. No one has ever really done anything nice for me."

Sirius stared hard at the stranger and then his face clicked when Sirius saw the hair.

"You're the purple-haired boy-" Sirius began.

"Shinso Hitoshi, yes," Shinso introduced himself. "You are…?"

"Oh, Sirius Blakefield." Sirius grimaced at having forgot his manners. He had just come to from being knocked out. Curious about that, he asked: "Um, how did you get them off me?"

Shinso's smile seemed forced. "My Quirk, Brainwashing. Personally, I think it's more sleepwalking related, but I can't go against the official report."

In awe at Shinso's ability, Sirius nodded. "Thank you."

Shinso shrugged. "By the time I got to you, you were already out. I just brought you to the nurse's office," he explained. He continued until the nurse arrived.

As the nurse dealt with his injuries, Sirius continued to ponder about Shinso's Quirk, already brainstorming possible ways to combat it.
