Ryuuji Narukami is the number one host at his club and can make any woman blush with a simple exchange of words. And to his surprise, Ryuuji can have that effect on men, as well.

When Saeyama, the landowner of the club where Ryuuji works, confronts him about seducing women who are “off-limits,” he immediately takes a liking to the popular host’s face.

Saeyama’s loyal right-hand man, Nejiro, gives Ryuuji an ultimatum: be his boss’s lover, or die. What kind of messed-up game is he playing!?

Just as Ryuuji thinks he has made the last decision of his life, he wakes up to find… a man with horns and a man who arises from the floor!? Where exactly is he? And how did he even get here?
