Hiyoshi

Hiyoshi serves a dual role as the commanding officer of the Shin-Yokohama Vampire Countermeasures Unit and the older brother of protagonist Ronald. Once a formidable frontline hunter, he transitioned to a police leadership position after sustaining an injury, earning the wholehearted trust of his subordinates Hinachi and Handa. While he projects a disciplined, justice-driven image in professional settings, he privately harbors an unexpected obsession with micro bikinis. Self-conscious about his youthful appearance, he has long worn a fake mustache to compensate—making him a character whose exceptional competence stands in absurd contrast to his personal quirks.
