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.
He was worried at first,
،كان قلقًا في البداية
Iruma hatte anfangs zwar Sorgen, ob das klappt
Al principio le preocupaba
Al principio estaba preocupado
Au début, il avait grand-peur
All'inizio, non sapeva se sarebbe sopravvissuto 
o se l'avrebbero divorato,
No começo, ele ficou preocupado se
sobreviveria ou se seria comido pelos demônios,
Первое время он страшно переживал…
вдруг узнают, что он человек, и съедят?
