Teisou Gyakuten Sekai Nara Moteru to Omotte Itara

In "A World Where Chastity is Reversed," society operates under inverted norms: women possess heightened sexual desires, and men are a scarce resource protected by bodyguards in a world with a one-to-twenty male-to-female ratio. Fifteen years after being reincarnated into this realm, which promised an effortless harem lifestyle, Ikuto Ichise finds himself surprisingly unpopular. He attributes his lack of romantic success to the presence of his exceptionally handsome bodyguards, particularly his high-spec childhood friend, Rui Toosaka. However, Ikuto remains completely unaware that his protectors are actually beautiful women disguised as men. His unguarded and overly familiar behavior toward them leads each woman to believe she has a genuine chance with him, inadvertently creating an oblivious harem around him. The situation reaches a turning point when Rui, who longs to be recognized as a girl, finally reveals the truth to him.
