Prologue

On a playground, there is a green-haired boy shielding a downed kid from three bullies.

"That's mean, Kacchan... I won't let you hurt him no longer," said a young Midoriya as she stood in between the kid and the bullies.

"Are you pretending to be a hero, huh, DEKU?" Bakugo shouted at him, "Even though you don't have a quirk," and suddenly the bullies charged at the young midoriya.

Then suddenly someone said, "What are you doing Bakugo to our brother?" while the said bully was ready to use his quirk on the young Midorya.

Bakugo just looked at them and made a tsk sound, dropping Midoriya. "You were lucky to have the rest of your quirkless brother here; you won't be lucky the next time," said Bakugo while he walked away. His lackeys followed suit without saying a word.

The bullied kid got up and exclaimed, "I didn't ask for help from a quirkless kid." Then he just ran away, leaving behind the people who helped him from the bullies.

The four kids who just got there let out a sigh of disappointment.
"C'mon, Izuku, let's go home," said one of his brothers while two of them helped him on his feet.

On that day, my brother and I found out that all men aren't born equal.
