Prologue

In a world where power defines worth, Kaizen Yaku was born with nothing. Quirkless, unwanted, and hidden away by a father who never claimed him, he spends his childhood alone, diving into books and building machines to fill the silence. But when his only friend is taken by the cruelty of others, Yaku makes a vow:

If he cannot be born a hero, he will build himself into one.

Armed with his genius mind, cutting-edge tech, and his AI companion Athena, Yaku enters UA University with a single goal - to become a hero worthy of being needed. But behind his cold eyes and unbreakable will hides a simple truth:

He just wants someone to say "thank you."
