As a human being, Iruma has prospered in the demon world and is highly sought after by his peers. It seems to be a natural thing for him to become the demon king, and it is also what his heart desires.
But at this moment, Grandpa Sullivan asked him to return to the human world and experience it before finally deciding whether to become the Demon King.
Iruma had no objection to this matter, because he knew that even if he returned to the human world, he would no longer be alone, and there would be many people around him to accompany him.
Asmodeus Ellis: Lord Iruma, your desire is to protect everything, and my desire, Asmodeus Ellis, is to protect you as a spear that pierces everything.
Kirio: Seeing the despair on other people's faces is a very enjoyable thing, until I discovered that the joy of being with you is greater than the pain in this world.
