Iruma Returned to the Human World After Becoming a Demon!

Iruma was sold to the devil by his parents when he was 14 years old. But he accidentally became the grandson of the ninth-level demon Sullivan, and became a student in the demon school. Until after the doomsday holiday, Suzuki Iruma was happily shopping with his grandfather. But he accidentally got separated and entered a magic circle by mistake. Opela, the accompanying housekeeper, took his hand and unexpectedly joined him - Return to the world. "..." "Huh?" It's been too long since I've been a human being, and it's really difficult to get familiar with the human environment again. Iruma comforted himself, luckily Opela was with him and he was not alone. However, why has it become so strange here! What curse? What superpower? He really doesn't know! ! Why take him away? ! Why would I encounter something so dangerous when I went out? What is that green and greasy thing? Ahhhh! Help! Encounter with the strongest human being and his students, encounter a person with super powers, and even change the clothes and the world will change! Nichirin sword and the boy selling charcoal. And ghosts. Iruma felt like crying but had no tears. Let him go back to Babers, even if the subject is torture every day. Let him go to school! * Suzuki Iruma entered a bad cycle due to special circumstances, and his character became calm and strong. But the suppression of one's own desires also diminishes. Until a certain emotional outburst, he grabbed Opela's collar and lowered his head. "Opela, will you always stay with me." The devil's answer was: "Always loyal to you." "Always with you." #On how Iruma became the Demon King# Ordinary Iruma: On the surface, he is innocent, but he is actually black. Iruma in the bad cycle: Strong and handsome, but actually very innocent. CP: Opela (a cat-type demon who shows a serious side but a sinister side and a very evil taste. (The evil cycle is a symptom caused by the devil due to excessive pressure, which makes him unable to suppress the destructive desires and desires in his heart.) Ps: It's privately assumed that Opera didn't know that Iruma was a human, and she didn't know until she arrived in the human world. When you come in, you will have CP. The interaction is just for the sake of sweetness. Intention: Make life happy!
