Kabura Honda, once human, endured a life fractured by chronic illness and hospital confinement, fostering deep-seated guilt over burdening others. Years of suppressing mundane aspirations and weathering familial neglect erupted in a crisis of despair, redirecting her path when Haru Nanakusa—a compassionate nurse—offered solace and transformed her into a vampire to escape suffering. Immortality granted her fleeting joys: savoring alcohol, forging connections, and defying former limitations, all shadowed by an unreciprocated longing for Haru. Post-transformation, Kabura reluctantly assumed guardianship of Haru’s daughter, Nazuna Nanakusa. Initial bitterness toward the fledgling vampire dissolved upon glimpsing Haru’s features in Nazuna, nurturing conflicted devotion blending maternal protectiveness with disquieting fascination. This duality fuels her resolve to fulfill Haru’s dying directive: mentoring Nazuna until she sires her first underling, securing independence. As a nurse, Kabura enforces clinical efficiency with icy professionalism, though flickers of dry humor surface during patient interactions. Her vampiric gifts—levitation, accelerated healing, and preternatural agility—complement a tactical cunning that has siphoned seven subordinates from rival covens. She ethically sidesteps direct blood consumption, relying on transfusion packs stockpiled with preserved human blood. Gloom and sardonic wit interlace her demeanor. She confronts intrusions with threats of bureaucratic retaliation, yet pragmatically bargains when defiance amuses her. Despite a frosty exterior, she offers quiet reassurance to those humiliated in her presence. Haru’s rejection and demise linger in rituals like chain-smoking—a hated habit mirroring her creator’s—and nostalgic dialogues with Haruka, a former ally from Haru’s circle. Kabura’s existence orbits unresolved grief and solitary resilience. Her stewardship of Nazuna and wary exchanges with Kou Yamori, Nazuna’s human ally, strain her poised facade, revealing fractures between obligation and suppressed yearning. Each action threads loyalty to Haru’s legacy with the silent toll of immortality—a testament to endurance forged in loss, eternally balancing duty against the ache of unlived human years.
