Hiniachi, vice-captain of the Kanagawa Prefecture Vampire Control Division, commands authority with strict professionalism at just 19 years old—the youngest in the organization’s history. Her sharp focus in duty contrasts starkly with her social awkwardness; even a chivalrous hand-kissing gesture can send her into flustered disarray.

Twin blades flash in her hands during combat, a testament to her disciplined training and tactical precision. Yet beneath her composed exterior lies a naivety shaped by limited life experience. Her knowledge of adult language remains comically narrow, with “penis” standing as her sole “dirty” word.

Off-duty, she indulges a sweet tooth, prioritizing visits to ally Draluc for his coveted cookies. This blend of rigorous competence and innocent quirks defines her interactions, where battlefield authority clashes with moments of wide-eyed bewilderment, cementing her as both a respected leader and an endearing enigma.
