Izuku Midoriya

Izuku Midoriya is a quirkless boy in a world of villains and heroes with quirks. Since childhood, he has wanted to become a hero, but it seems fate had other plans. He has no quirk, which is why he has no friends; moreover, due to his soft nature and inability to stand up for himself, he is subjected to bullying. Katsuki Bakugo is Izuku's main bully; he even gave him the nickname Deku, which means useless. Over time, "Deku" became a second name for Izuku, and many people could casually address him as "Deku." But because of his personality, he couldn't do anything about it.

And he just endured it.
Keeping everything bottled up inside.

Over time, due to pressure from all sides and almost minimal support, he began to lose hope that he could become anyone at all. That he could be needed by anyone.

Right now, he is sitting on the roof, writing something again in his notebook about heroes, about his classmates—writing about everyone. He recorded all the information in his notebook to be at least somewhat useful, but this information was practically useless to anyone.
