Due to very bizarre circumstances, the human boy, Suzuki Iruma, ends up in the netherworld. He is keeping the fact that he is human a secret and attends the Demon School Babyls. Because he is human, he cannot use magic so he had been using the Gluttonous Feeder Ring to get by in school. But then one day, the ring started to speak! Why, though? Iruma then meets the incarnation of the ring who calls themselves Alicred, AKA Ali-san.
So, Li'l Iru, you got any leads? 
You seem amped up.
.إذًا يا إيرو الصّغير، هل لديك أيّ دلائل؟ تبدو متحمّسًا
Und, Iru-boy, hast du schon eine Spur?
¿Tienes alguna pista, Iru?
¿Tienes alguna pista, Iru?
Alors, mon garçon,
Quindi, piccolo Iru, hai qualche indizio? 
Sembri lanciato.
Então, Irubo? Alguma pista?
Você parece bem empolgado.
Так что, Ирумка, знаешь, с чего начать?
Настрой, признаю, мощный.
