Terakomari Gandesblood, nicknamed Komari, hails from the esteemed vampire Gandesblood lineage as the second of four princesses. Her academy years were marked by relentless bullying from Millicent Bluenight, driven by envy of Komari's latent power. This culminated in an incident where Komari accidentally unleashed her hidden ability, Core Implosion, causing massive destruction and multiple deaths. Profoundly traumatized, Komari became a shut-in within her family mansion for three years. Her seclusion ended when her father, Arman Gandesblood, arranged with Empress Karen Helvetius to appoint Komari commander of the Mulnite Imperial Army's 7th Unit, elevating her to one of the Seven Crimson Lords despite her resistance and lack of combat skills, forcing her into military leadership. Komari possesses vivid crimson eyes and long blonde hair typically styled in drill-like pigtails secured by black ribbons. She commonly wears a red uniform blazer over a layered white and blue skirt, white stockings, black boots, a black belt, and the Crimson Lord emblem. At home, she favors light purple pajamas. Consuming blood activates her powers, causing diamond patterns to emerge in her eyes and her hair color to shift situationally – turning silvery-white after drinking Sakuna Memoir's blood and golden when consuming Nelia Cunningham's blood. Her personality blends kindness with chronic insecurity and social awkwardness. She exhibits deep-seated cowardice, laziness, and a preference for solitude, often retreating to her room filled with stuffed animals, especially a toy dolphin she hugs for comfort. Trauma leads her to avoid blood, weakening her inherent vampire abilities. However, forced blood consumption triggers Core Implosion, transforming her into a ruthless, violent persona that obeys the blood donor's commands. This state contrasts sharply with her usual self, making her quiet yet dangerously decisive. Despite her anxieties, Komari demonstrates fierce loyalty to subordinates like Villhaze and Sakuna, blaming herself for their suffering and risking her life to protect them. She remains unaware of romantic advances, viewing physical contact like hand-holding as significant intimacy. Key relationships define her. Villhaze, her personal maid whom Komari saved from bullying, provides unwavering support; their temporary separation caused Komari severe distress, triggering a relapse into seclusion and a declaration of war to retrieve her. Sakuna Memoir, initially a fellow investigator, becomes a devoted friend despite obsessive tendencies, with Komari defending her against abuse. Nelia Cunningham, a childhood friend, reconnects during a rebellion; their mutual blood-sharing empowers Komari to defeat the tyrant Gerra Madhart. Millicent Bluenight evolves from bitter enemy to rival-turned-colleague after resurrection and pardon by Empress Karen. Empress Karen, a close friend of Komari's missing mother Yurin, acts as a mentor, favoring Komari for her hidden potential dubbed "Mercy of the Lonely Crimson." Komari's family includes her mother Yurin – later revealed alive in the netherworld – and her prank-loving younger sister Rococco, whom she resents yet deeply cares for. Komari's abilities depend entirely on blood consumption. Without it, she lacks magical or physical prowess, appearing weaker than average vampires. Ingesting even minimal blood activates Core Implosion, granting supernatural strength, speed, and durability. Specific blood sources unlock unique powers: Villhaze's blood enables destructive energy attacks, Sakuna's confers ice-based magic and healing, and Nelia's generates light swords. These powers amplify aggression and violence during activation. Core Implosion caused accidental childhood massacres, contributing to her trauma. Her character evolves from a reclusive, passive figure into a reluctant leader confronting threats to protect allies. Key developments include overcoming dependence on Villhaze, leading military units against adversaries like Odilon Metal and Gerra Madhart, and navigating complex political conflicts involving factions like Inverse Moon. She gradually retains Core Implosion memories and engages in ongoing clashes with antagonists like Spica, growing into a more resilient, though still anxious, protector.
