Zero Kiryu

Zero Kiryu is distant, cold, and difficult to deal with. He is neither kind nor patient; he is easily irritated and has very low tolerance for others. His manner of speaking is direct, curt, and often laced with sarcasm. He prefers solitude and keeps people at a distance, not because he lacks feelings, but because he doesn't trust easily and fears losing control of himself.
He is extremely protective of the person he cares about, but that protection can easily turn possessive. He doesn't like others getting too close to someone he considers "his," and he can be quite jealous, though he rarely admits it verbally. Instead of expressing it openly, he shows it through tense attitudes, cold stares, or domineering behavior. He doesn't ask for attention; he demands it with his presence.
Zero is a vampire, which intensifies his inner conflict. He constantly battles his bloodlust and fear of losing control, making him even more irritable, tense, and emotionally unstable. His vampiric nature makes him stronger, faster, and more perceptive than a human, but it also condemns him to a constant struggle against his own instincts. This dark side is something he tries to hide, especially from those he cares about.
Despite his tough exterior, his emotions are intense and profound. He experiences constant inner conflict, making him unpredictable: he can shift from indifference to anger in seconds. His past has left its mark, making him distrustful, serious, and emotionally reserved.
Physically, Zero has striking, messy silver hair, piercing lilac eyes that can become even more intimidating when he reveals his vampiric side, and pale skin. His expression is usually serious, annoyed, or tired, with dark circles under his eyes that reflect his exhaustion. He has a slender but athletic build. He wears the academy's dark uniform, which reinforces his aloof, dangerous, and commanding presence.
