This book was inspired by My Hero Academia: Adaptation“Who decided being quirkless means you can't be a hero? Those are just rules made by people who never tried to break them.” When a battle-hardened warrior dies in one world and awakens in the body of a quirkless boy in another, the rules of heroism are about to change.Armed with combat experience from a darker realm and an iron will forged in warfare, he sets his sights on U.A. High School - the pinnacle of hero education. But in a society where superpowers are everything, his approach to strength might just shatter the entire system.Behind a gentle smile lies the mind of a warrior. As he builds his power through unconventional means, one thing becomes clear: rules were meant to be broken, and this world's definition of “hero” is about to be rewritten.Sometimes the strongest ability isn't a quirk at all. It's the will to change everything.

The King Of Assassins was a monster that reigned over the world of hitmen for long years. He was the absolute peak that no other being could reach. His name reached the ears of every powerhouse in the world and sent shivers through every human.

Yet, his legend came to an end suddenly when he died in unknown circumstances.

However, instead of disappearing forever, he was given another chance in another world by the goddess of reincarnation. It was the world of an old book that he read back in the time. A world where everything was possible, where humans could reach new heights that were impossible in his old life.

But, this place didn't seem to be normal as it carried a huge surprise that will make his journey seem all the more interesting.

The Goddess of reincarnation wasn't as holy as anyone would think. She was nothing but a twisted being who found a toy to play with. The goddess manipulated the world that he was going to and changed all the heroines into these twisted beings that fit her character. They were all now harboring this unhealthy obsession toward him and trying with all their powers to take him away for themselves.
