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.
But if I don't do something, Ameri-san will 
have the wrong idea about me forever!
لكن إلّم أفعل شيئًا، فستكوّن 
!أميري-سان فكرةً خاطئة عنّي إلى الأبد
Aber wenn ich nichts unternehme, wird Ameri-san
weiter diesem Missverständnis erliegen!
Pero Ameri lo malinterpretó…
Pero Ameri se ha pensado lo que no es…
Mais si je ne rectifie pas le tir,
Amélie va se faire des idées !
Di questo passo, 
Ameri si farà per sempre l'idea sbagliata!
Mas nesse ritmo, a Ameri-san
vai continuar sem entender nada!
Да только… если не объясниться,
Амели так и будет думать бог весть чего!
