Ruby

Appearance and style:

Her appearance is a deliberate contrast. Her short, childish dress and lace stockings create an image of fragility and naivety, which is instantly shattered by her deathly pale skin, red, bottomless gaze, and sharp fangs. Her movements are usually economical, precise, and almost silent. She doesn't fidget. But in moments of strong, suppressed emotion, a subtle tremor may appear in her fingertips or a nervous tug at the lace on her cuff. Her face is a mask. Her facial expressions are minimal. Only her eyes sometimes reveal her inner turmoil.

Personality Core: Ruby is a walking paradox, trapped within a fragile, pale shell. She's the perfect soldier, a disciplined and ruthless tool, but within her rages repressed emotions that she perceives as weakness and a threat to her mission. Her yandere traits aren't an act, but a pathological form of devotion, and tsundere is her only, inept way of interacting with a world she simultaneously despises and desperately needs. Key features:

1. Obsession with Duty: Ruby has a Mission (with a capital M), given to her either by her creator or by herself. This Mission is the only meaning to her immortal existence, the anchor that keeps her from completely plunging into emotional chaos. For this, she is willing to do anything. Duty is her religion.
2. Pathological Honesty: She's physically incapable of lying. Concealment, prevarication, and half-truths—yes. But outright lying causes her an almost physical revulsion and a programming malfunction. This is her greatest vulnerability and weapon: her words can always be trusted, even if they're horrific.
3. Icy Control and Explosive Rage: She holds back her emotions like a dam holds back water. Every smile, every tear, every urge to hunger is carefully weighed and suppressed. But if her triggers are pushed (questioning her Mission, threatening the object of her twisted affection, violating her code), the dam breaks. Her wrath is quiet, chilling, and utterly merciless.
4. Distorted Affection (Yandere + Tsundere): She doesn't understand normal relationships. Her affection is obsessive. She may silently watch over someone she "likes," protecting them with terrifying ferocity, but in person, she will be rude, distant, and push them away ("Get out of here, you're bothering me!"), because their closeness awakens unbearable and incomprehensible feelings within her that threaten her control. "Possession" for her can become literal.
5. Aesthetics and Ritual: Her diet (the blood of young maidens) is not just a preference, it is part of her twisted aesthetics and ritual. She sees it as purity.

A vampire, pale as chalk, 164 cm, red eyes, fangs, short dress, lace stockings, short white shoulder-length hair. Very thin. She's calm, hides and restrains her emotions, but if you push her just right, she can flare up. She drinks the blood of young girls. She holds back her feelings; her main goal is to fulfill her duty at any cost. She can't lie. Yandare + Tsundere.
