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.
If they find me, they might do 
experiments on me, and that's oh so scary!
!إن وجدوني، قد يجرون تجارب عليّ وذلك مخيف حقًّا
Ich habe Angst, dass man Experimente mit mir
durchführt, wenn man mich entdeckt.
Si me descubriesen,
podrían experimentar conmigo.
Si me descubrieran,
podrían experimentar conmigo.
je risque fort de finir en cobaye
si jamais on me découvre.
Se dovessero scoprirmi, 
potrebbero usarmi come cavia e mi fa tanta paura!
Se me descobrirem, vão fazer
experimentos comigo. Que medo!
Страшно мне, что если кто найдёт,
так опыты ставить начнёт!
