He became a teacher at the best magic academy in the empire.
….For being mistaken for someone else.

Hamel, a warrior who traveled with his colleagues to exterminate the devil. Yet, he died just before the battle with the devil started.

“Yes.”

What the hell?

He was reborn as the descendant of his fellow warrior, Vermouth.

And, a reincarnation of an unknown origin, the reality of living together with the demons.

Facing a new world where everything is questionable.
