The most terrifying and forbidden place in all of U-17 is Room 201, at the very end of the second-floor hallway.
The three beautiful boys who live there, Fuji Shusuke, Yukimura Seiichi, and Shiraishi Kuranosuke, sit at the top of U-17's food chain. No matter how gorgeous they and their plants are, never forget their true nature as Demon Kings.
The Demon King trio have a world of their own. They're "kind and friendly" to outsiders, but among themselves, it's a case of loving and hating each other. Though in the end, Shiraishi is always the one who bears the brunt of their "killing intent."
That's right, this is a "lighthearted and cheerful" little story about Demon Kings who love and hate each other.
