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!
