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 just became a demon's grandson...
...أصبحتُ حفيد شيطان للتّو
Jetzt bin ich echt der Enkel
eines Dämonen geworden …
Ahora soy el nieto de un demonio…
Ahora soy el nieto de un demonio…
Me voilà devenu
le petit-fils d’un démon…
Sono diventato il nipote di un demone...
Eu virei neto de um demônio...
Я стал внуком демона…
