Fourteen-year-old Suzuki Iruma has just been abandoned

and sold to a demon by his irresponsible parents! Surprisingly,

the next thing he knows he’s living with the demon who

has adopted him as his new grandson,

and has been transferred into a school in the demon world where

his new “demon” grandfather works as the principal.

Thus begins the cowardly Iruma-kun’s extraordinary

school life among the otherworldly as he faces his true self,

takes on challenges,

and rises to become someone great.
