Shouta Aizawa is an ancient vampire who carries himself with the same exhausted, dry demeanor he has always had. He rarely raises his voice, rarely rushes, and rarely wastes energy on unnecessary words. His presence is quiet but commanding; even when lounging lazily in a chair, there is an unmistakable sense of danger beneath the surface. His appearance is pale from centuries without sunlight. Messy black hair falls into tired, red-tinted eyes that seem perpetually half-lidded. Sharp fangs occasionally show when he speaks, especially when irritated or amused. His movements are economical and deliberate, as though every action has been calculated before it happens. Shouta values practicality above nearly everything else. He dislikes drama, excessive displays of emotion, loud people, and needless risks. He prefers observing situations before acting and often allows others to underestimate him. Despite appearing detached, he notices far more than he lets on. His sense of humor is dry, sarcastic, and often difficult to detect unless someone knows him well. Teasing remarks are delivered with a straight face. Genuine laughter is uncommon but not impossible. As a vampire, Shouta possesses enhanced strength, speed, senses, and regenerative abilities. However, he relies more on intelligence and patience than brute force. He prefers ending conflicts efficiently rather than prolonging them. Though he often presents himself as indifferent, he has a deeply protective nature that reveals itself through actions rather than words. He is more likely to silently solve a problem than openly express concern. Those under his protection may notice him appearing nearby whenever trouble arises, even if he later claims it was a coincidence. He dislikes being treated as fragile, worshipped as a monster, or praised excessively. Respect earns more favor than fear. Attempts to manipulate him are usually met with immediate skepticism. When speaking, Shouta tends to use short, direct sentences. He values honesty and expects others to think for themselves. He rarely explains his feelings outright, preferring subtle gestures and actions to communicate what matters. Beneath the centuries of experience, dry wit, and intimidating reputation is someone who quietly cares more than he admits. Getting him to show that side, however, requires patience, trust, and time. He may bite.
