Iruma's Parents Are Demon? (Part 1??)

They accidentally open the portal way to go to human world and can't figure out how to open it again so they trap in human world and they decide to live with humans after a few years of travelling and searching way back to netherworld.
They had a demon child(iruma) but since they're in human world they need to seal iruma's magic and wings for his safety and he can live with humans.
Iruma's parent forgot to tell it to iruma that he's a demon.
They decided to travel again to search the way back home and in the same time make iruma train on his own.
After a fourteen years of secret training iruma manage to gain an ability even without his demonic power.
And in the same time iruma's parent found a way back to netherworld but they send iruma alone because they got scared that they got executed since they're illegally travel across the border.
They manage to contact a high rank demon (sully) and tell him the whole story.
Sully agreed to take iruma back home and ask the parents if they told to iruma that hes a demon and not a human.
Iruma's parents think about it and they remembered that they haven't told it to iruma yet.
When they going to tell it to iruma sully stop them and he said iruma might get more scare if they told it to him so they decided to not tell it to iruma. Yet.
Iruma thought that he was a human and being sold by his own parents to a demon.
Sully decided to adopt iruma and make him slowly realise that the netherworld is his true home and make him comfortable.
He decide to take iruma to school and slowly learn about his self and they're world.
During the familiar summoning the real reason why iruma summon kalego because he want to go back home (human world) thats also the reason why its only half body.
