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!
and then had the nerve to cause such a 
ruckus right afterward on the same day...
...ثم تجرّأ على التسبّب في فوضى بعد ذلك وفي نفس اليوم

un hechizo vulgar y luego tuviera
el descaro de armar un alboroto…
pour lire des horreurs en public
et s’amuser à déclencher des bagarres…
e osasse causare un bel trambusto lo stesso giorno...
e então teve a coragem de causar uma
comoção logo depois, no mesmo dia...
а затем в тот же день
поднимает на уши всю школу…
