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.
Iruma had no way of knowing the 
tumultuous future that awaited him.
.لم يستطع إيروما معرفة المستقبل المضطّرب الّذي ينتظره
Iruma konnte ja noch nicht wissen,
welches erschütternde Schicksal
Iruma aún no era consciente
del agitado destino que le esperaba.
Iruma aún no era consciente
del agitado destino que le esperaba.
Iruma n’avait aucune idée
du destin tumultueux
Iruma non poteva sapere 
che lo aspettava un futuro tumultuoso.
Iruma não tinha como saber
o futuro que o esperava.
А Ирума ещё и не знает, какие потрясения
готовит ему судьба-злодейка.
