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.
Maybe imagine me with big eyes, curvy, 
and with long, skinny legs so I look hot!
ربّما عليك تخيّلي بعينين كبيرتين وسيقان 
!منحنية وطويلة ونحيلة لجعلي أبدو جذّابًا
Ich möchte cool sein, mit großen Augen,
einer schönen Taille und langen Beinen!
Quiero ojos grandes,
cintura delgada y piernas largas.
Quiero ojos grandes,
cintura delgada y piernas largas.
Un regard de braise,
une taille fine et de longues jambes.
Visualizzami con occhi grandi, vita stretta
e delle lunghe gambe magre così sarò figo!
Talvez se me imaginar com olhos grandes,
com uma cinturinha, pernas compridas e magras!
Чтоб большие глазки были, пышная шевелюра
 и длинные ещё ножки… В общем, отпадно!
