A world of reversed chastity— A dreamlike society where the male-to-female ratio is 1:20, women have much stronger sexual desire, and the precious few men live a smooth, protected life surrounded by elite bodyguards. It’s the perfect world for a guaranteed harem. Fifteen years have passed since Ichi­se Ikuto was reincarnated into this world… Yet for some reason, he’s still not popular. All the bodyguards around him are handsome, and among them, his best friend Tōsaka Rui is especially high-spec—surely that’s why he can’t get any attention… or so Ikuto thinks. But in truth, all those “handsome bodyguards” are actually beautiful girls cross-dressing as men! Completely oblivious, Ikuto gets way too close to them without any self-awareness, constantly giving each girl the feeling that they might have a chance with him. While he unknowingly forms a harem around himself, Rui—who desperately wants him to see her as a girl—finally bares everything to him…!? A high-demand protagonist and a nonstop popularity streak— The ultimate unconscious-harem romcom begins!
