Suzuki Iruma is too nice and just doesn’t know how to say no. One day, he somehow gets dragged into the netherworld where the demons live. He arrives at the great demon Sullivan’s mansion where he is asked to do the unthinkable... and ends up becoming Sullivan’s grandson! He is quickly enrolled into the Demon School Babyls where Sullivan serves as chair-demon. Iruma begins his super exciting school life at demon school while trying to conceal the fact that he’s a human!
but you won't be eaten as long as 
they don't find out you're human!
!لكنّهم لن يلتهموك ما داموا لا يعرفون أنّك من الإنس
no te comerán
si no descubren que eres humano.
no te comerán
si no descubren que eres humano.
Arrange-toi pour ne pas être repéré
et nul ne te mangera.
ma non potranno mica mangiarti
 se non scoprono che sei umano!
mas você não será comido, desde
que não descubram que é humano!
но если не узнают, кто ты,
то и не съедят.
