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.
As for how I'm speaking right now... 
I haven't the foggiest!
!أمّا بالنّسبة لكيف أتكلّم الآن... فأنا لا أملك أدنى فكرة
Ich weiß nicht, warum ich
jetzt reden kann!
No sé por qué de repente puedo hablar.
No sé por qué de repente puedo hablar.
Par contre, j’ignore comment ça se fait
que je puisse parler !
Ora come ora, mentre ti parlo... 
Non ne ho la minima idea!
Por que eu estou falando? Sei lá!
Ну а с какой радости я вдруг заговорил…
в душе не представляю!
