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.
Thus Iruma began his life with the incarnation 
of the Gluttonous Feeder Ring, Ali-san.
.وهكذا بدأ إيروما حياته مع تجسيد الخاتم الشّره، ألي-سان
Und so begann für Iruma ein Leben mit Ari-san,
der Manifestation vom Ring des abartigen Fressens.
Y así es como Iruma empezó
a convivir con Ari, el Anillo Voraz.
Y así es como Iruma empezó
a convivir con Ari, el Anillo Voraz.
C’est ainsi qu’Ali,
l’esprit de la bague gloutonne,
E così, Iruma cominciò a vivere insieme 
all'incarnazione dell'Anello Divoratore, Ali.
E assim, Iruma começou sua vida ao lado
da encarnação do anel glutão, Ali-san.
Вот так Ирума и стал жить с дядей Али —
воплощением кольца «Пожиратель».
