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!
I need to do everything
I can to not be noticed.
.يجب أن أفعل كلّ ما في استطاعتي حتّى لا أبرز
Ich darf sie nicht anschauen …
Nur nicht auffallen …
Haré todo lo posible
para no llamar la intención.
Haré todo lo posible
para no llamar la atención.
Tâchons de passer inaperçu.
Invisible, même.
Devo fare tutto il possibile 
per non attirare l'attenzione.
Eu preciso fazer tudo.
Não posso ser notado.
Всё сделаю, лишь бы не выделяться…
