Kazuya's friend Shirou has a tendency to ask girls out without a lot of planning or concern about the outcome. Just when it seems like that approach has finally managed to endear himself to a girl, the looming threat of an amasogi puts a damper on any potential romance.
What threat awaits us when we 
enter this gender-swapped world
ما الخطر الذي ينتظرنا عندما ندخل عالم تبادل الجنسين هذا
Welcher Gegner wartet auf uns
in dieser alles verändernden Welt?
¿Qué amenazas nos acechan
mientras exploramos
¿Qué amenazas nos acechan
mientras exploramos
Quel ennemi nous attend
dans ce monde inversé ?
Che minaccia ci attende una volta entrati
in questo mondo di scambio di generi
Quais ameças nos espera ao
entrar no mundo invertido
Чтобы раскрыть дело, мы прыгаем
в перевёрнутый мир, где поджидает враг!
