The Anime Lad
Iruma Suzuki has spent fourteen years accommodating irresponsible adults. When his parents hand him over to a demon, he expects the arrangement to worsen. Instead, his new guardian adopts him enthusiastically and enrolls him at a demon school. Iruma must conceal that he is human while navigating classes and a grandfather incapable of low-key affection. Hell provides a measurable improvement in parenting.
Super Eyepatch Fox
A demon adopts Iruma and sends him to the school he runs. The human student must blend into classes without exposing what he is. Iruma is timid, accommodating, and desperate to avoid attention. Demon school has other, much louder plans for his quiet life at every turn.
Gigguku
Iruma is sold to a demon and somehow lands with the most overcommitted grandpa alive, which is already perfect! Then school begins, and this timid human keeps drawing attention while trying to look completely ordinary. The demon world should be terrifying, yet his new home is warmer than the one he left. That reversal gives every loud school gag a soft center.
Father's Basement
The bright school comedy can look aimed at viewers much younger than its best jokes. Give it room. Iruma is not passive because the script forgot to give him a spine. He has learned to survive by pleasing everyone and avoiding danger, so demon school exposes that habit from comic angles. The premise gets softer as his new home treats him better than the human world did, without losing its appetite for chaos.
