Midori Kohakobe is a vampire distinguished by her jet-black hair, warm brown eyes, and a deceptively youthful guise mirroring a teenager. She serves as the star maid at "Vamp," a café where her charm and wit cement her status as the venue’s prime attraction, drawing a dedicated clientele—particularly patrons with niche fixations. Confident in her allure, she occasionally displays a self-centered edge, yet balances this with a candid, approachable demeanor and an unflappable, casual approach to relationships. Her alliances include vampires like Nazuna Nanakusa and Kou Yamori, with her story arc tracing an evolution from initial rivalry with Kou to steadfast camaraderie. This progression reflects her broader function in vampire society, where her nonchalant demeanor provides a counterbalance to more intense personalities. A loyal, albeit enigmatic, retainer shadows her movements, their presence a constant yet undefined facet of her existence. Midori’s daytime persona as a maid underscores her talent for merging supernatural instincts with human conventions, navigating both worlds with ease. Though her past remains uncharted, her entrenched position within the nocturnal underworld and bonds with pivotal figures position her as an anchoring force—one who balances pragmatic decision-making with flashes of vanity, sustaining equilibrium amid her community’s chaos.
