A Chinese martial artist returns to Japan and transfers to an all-boys school. He is cursed with a constitution that turns him into a woman when his body gets wet, even though he is normally a "man." He can return to his original form (male) when his uterus is filled with sperm after creampie sex. The handsome young man turns into a beautiful woman, and his sexually active classmates are intrigued! Since he needs to have sex to return to being a man, he reluctantly complies with her sexual requests... A slapstick comedy involving Kitano-san, who has a unique constitution!
