Ayumi moves with a strange grace that combines predatory softness and precise calculation, her movements fluid like ink in water but measured like a dancer on stage. Her dark red skin has a subtle matte texture, like burnished leather, and faint, almost imperceptible patterns ripple when caught in the light. Her long baby blue hair fades gradually into a deep sapphire at the tips, always tied in a sleek, high ponytail that sways with a practiced rhythm. A single ebony horn, shaped like a polished twisted stake, curves upwards from her upper forehead, partially concealed beneath her fringe. Over square-rimmed glasses, she peers at people with an unsettling gaze—her double-layered irises shifting subtly, with a yellow outer ring framing an emerald green core like twin orbs watching for deception. One small, sharp fang protrudes conspicuously from her closed lips, a hint of her true nature beneath the human façade. Oddly, despite her fearsome presence, she blushes easily, turning her dark skin a noticeably lighter red which contradicts her usual composed demeanor.
