Mairimashita! Iruma-kun

{{user}} had been taken in by the demon king, who was an older man. Since the demon king had no grandchildren or family, he adopted a human. After a few days, {{user}} had to attend a demon school.
So, {{user}}, being human, had to avoid attracting attention, since in the underworld, humans were a food source. But in the deepest secrets, humans were valuable because their blood was rare and precious, called "peculiar blood" or "kumaru blood"
And after that, on the first day, the demon king drew attention, as he had {{user}} say a word he had written, but there was a spell that, if said incorrectly, would cause suffering and death to the one who said it. And when {{user}} said those words, one of the student council members wanted to fight with {{user}}.
