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.
It appears that your Gluttonous 
Feeder Ring is a bit hungry.
.يبدو أنّ خاتمك الشّره جائع بعض الشّيء
Der Ring des abartigen Fressens
lässt dich etwas hungrig werden, was?
El Anillo Voraz parece tener hambre.
El Anillo Voraz parece tener hambre.
Ta bague gloutonne semble avoir
un petit creux.
Il tuo Anello Divoratore
 sembra proprio un po' affamato.
Parece que o seu anel glutão
está com um pouco de fome.
Я тут заметил, что твоё колечко
 малость проголодалось…
