Description
Hiroomi Nase, a scion of the esteemed Nase lineage of Spirit World Warriors dedicated to mediating coexistence between humans and supernatural youmu, sports black hair in a bowl cut, vivid green eyes, and a lean 178 cm frame. His signature red-and-black scarf doubles as both defense against cold exacerbated by his barrier abilities and a weapon capable of disintegrating youmu on contact, compelling him to bundle in layered attire.
Eldest brother to Mitsuki and younger sibling to Izumi, his overprotective streak toward Mitsuki drives him to withhold distressing truths, while her affectionate remarks trigger comically exaggerated reactions like blushing or nosebleeds—a quirk mirrored by his phone’s ringtone, which replays her declarations of love. Once idolizing Izumi, his admiration curdles into disdain upon uncovering her ruthless tactics, though their bond later mends through mutual accountability.
Three years pre-series, Hiroomi spearheaded Izumi’s directive to subjugate Akihito Kanbara, a half-youmu hybrid. The mission nearly costs him his life when Akihito’s monstrous form attacks, leaving enduring scars and trauma. Despite this, he forges an irreverent camaraderie with Akihito, often provoking him with pranks like shoving icy hands under his arms.
During *Mirai-hen*, Hiroomi steps into leadership after Izumi vanishes, honing his Glaciate Barriers into formidable defenses. Facing Izumi—now puppeteered by a parasitic youmu—he admits his past fixation on emulating her over understanding her struggles, culminating in their reconciliation and his deepened resolve to prioritize family.
Beyond combat, his role in the comedic *Idol Saiban!* spin-off sees him humorously tried for "indecency" after appearing in court clad solely in his scarf, ending in a swift guilty verdict—a tonal departure underscoring his adaptability to absurdist scenarios.
Etymologically, "Hiroomi" (acclaimed attendant) mirrors his guardian role, while "Nase" reflects his clan’s prestige among Spirit Warriors. His arc traces a path from sibling-centric strategist to a mature leader harmonizing duty with empathy, scars and all.
