Love bites, and so does he—but only when the neck is ripest. In this adaptation of Hiromasa Okujima's cult manga, 450-year-old vampire Ranmaru (Ryo Yoshizawa) works at a traditional bathhouse while stalking his next meal: 15-year-old heir Rihito (Rihito Itagaki), whose virgin blood he craves. When Rihito falls for a classmate, Ranmaru declares war. His desperate sabotage attempts turn the town into a battlefield of cockblocking chaos. Director Shinji Hamasaki delivers this BL-tinged bloodbath with fang-sharp wit, featuring a 2025 remix of the classic bathhouse anthem "Ii Yu da na." One question remains: is protecting your dinner's virginity harder than immortality itself?
