The Reincarnation of an Ordinary Person With Unparalleled Effort ~If You Work Hard From the Time You Are a Baby, Before You Know It, You Will Be Carrying the Future of Japan on Your Shoulders~

Itsuki, a boy who was killed by a random attacker and reincarnated.

He reincarnates into a world where monsters called “Magui” exist in Japan – and he’s born into a family of “Exorcists,” who use magic to exterminate monsters!

Children of Exorcists are often targeted by Magui and if they’re weak, they’ll be killed again.

So Itsuki made up his mind. To become strong – to never die again.

He diligently practiced magic from infancy aiming for the strongest… only to realize.

“Oh no… I’ve worked too hard…”

A regular person who worked too hard but became the strongest!?

A fantasy tale of overwhelming effort to defeat all the Magui with extraordinary power!
