Personality
Devoted sister-complex
Unshakeable composure under pressure
Hypersensitive to cold
Outwardly playful yet shrewdly calculating
As the firstborn of the esteemed Nase lineage, Hiroomi perpetually wears a scarf to combat the debilitating cold sensitivity caused by his own supernatural abilities—a garment that doubles as a formidable weapon in battle. In everyday life, he showers his younger sister Mitsuki with an almost theatrical level of affection and keeps the mood light with wit and dry humor. Yet when stakes are highest, this laid-back facade gives way to razor-sharp focus, as he fulfills his solemn duty of monitoring Akihito Kanbara and safeguarding the Nase family's interests.
