Thirty-two-year-old Itto Tsuruoka is single and has recently taken a position as a janitor at an all-girls high school. Despite his ordinary circumstances, he quickly becomes captivated by a student named Sayaka Asahimura, firmly believing she is the woman he will one day marry. His quiet routine is shattered when he hears a distressed scream from behind the school building. Rushing to investigate, he discovers Sayaka in a state of panic over a frog that has somehow found its way inside her clothing. The situation is far more dangerous than it initially appears, as Sayaka suffers from a severe allergy to frogs, which rapidly causes her to lose consciousness. Neither the attending teacher nor Sayaka’s friend dares to touch the unusual pink amphibian, terrified that it might be poisonous. With no one else willing to act, Itto steps forward and risks his own safety to rescue her. After managing to extract the creature, he realizes the exotic frog has latched onto a cut on his finger and is actively draining his blood. The sudden loss of blood causes Itto to collapse into unconsciousness. However, when he finally awakens, he discovers that the bizarre encounter has transformed him into an entirely different person.
