The supporting character's harem is very normal - Chapter 37 Miam!

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.

In every being, a soul, a spirit, or a core, exists that tethers the consciousness into the solid plain. Witness as how a little spark from who was once a blazing flame, regained what once was lost.“I died and..” grins “...that started my life”What happens when an assassin transmigrated to a cultivation world?They rise through a mountain of corpse to reach the skies.But....What of an assassin whose enemy turns out to be themselves?A world where magic and cultivation co-exist?People say “Keep moving forward”.What if the way forward, is to go back to where she begun?

I don’t know the length of Hydra, or the depth of S.H.I.E.L.D.

I don’t know that Ant-Man has an outfit, and I don’t know that the Winter Soldier has an iron fist.

I don’t know that there is chaos in the Bliss Space, and I don’t know that Miss Xiaoyu wants to get married.

I don’t know if the walking corpse is cheating, I don’t know whose fault the alien is.

I don’t know the legend of mutants, I don’t know that Kryptonians can’t afford to provoke them.

I don’t know that Black Panther’s family has a mine, and I don’t know that Iron Man is a mess.

I don’t know what happened to Lei Shen’s family, and I don’t know that Thanos is thinking about making troubles.

He doesn’t know the past or the way forward, he only knows that he stands firm at the critical moment and cannot be cowardly.
