[Urban + Funny + Single Female Protagonist + Aristocratic Family + Demon Hunting]
Blue Star, a magical world controlled by humans.
But there are many monsters, ghosts, demons, and alien races inside, trying to subvert the human race's rule over Blue Star.
At this critical moment, a young man suffering from "narcolepsy" and his friends slowly walked into the sight of all forces.
And how can he, who has multiple mysterious identities, save the endangered human race?
I don't mind writing multiple heroines.
