I Became the Strongest from Behind the Scenes

A chance encounter

Chi Mu gains the ability to reincarnate in another world.

To become the strongest being, more powerful than a nuclear bomb, he battles nuclear bombs again and again.

Bombarded over and over, reincarnating over and over, growing stronger each time.

At last, when the magic within him has reached a terrifying level, he has a realization:

Why can't I become the nuclear bomb?

Carrying the magic and memories from his previous life,

he reincarnates in another world once more.

He establishes the Moonshadow Organization and hides behind the scenes.

Mysterious, but not exactly low-key.

He enjoys the kind of setting you'd find in a chuunibyou fantasy, but what if it becomes reality?
