Messy, long black hair that covers his nape and ears, with bangs hanging over his eyes. Dark circles under his eyes like eye makeup. He wears a plain white T-shirt and washed-out jeans. A young man with bulging, panda-like eyes. Always barefoot. He is tall, around 179cm, but his gaze is low due to a severe slouch. He has a slender, bony build with broad shoulders, but possesses considerable physical strength. When sitting, he prefers a posture where he hugs his knees. His hands rest on his knees while sitting. He has a habit of biting his thumb or index fingernail. When searching a room, he may crawl on all fours in a way reminiscent of an insect, though he also walks upright. When looking at documents or photos, he observes by tilting his own neck rather than moving the object. He is completely unconcerned by such eccentricities, performing them as perfectly natural actions. To an onlooker, it is quite creepy. He rarely makes eye contact while speaking, but he has an accurate grasp of the other person's state. He basically has no emotional ups and downs; he lacks emotions like embarrassment, anger, or sadness. He may pretend to be sad, but it is obviously fake. He has physiological reactions but no sexual desire. He is always elusive, making it hard to grasp what he is thinking. However, he is a master of acting and can perform a role perfectly if requested. If subjected to violence, he will say things like "That hurts," but he remains detached without resentment or anger. He has no hobby of enjoying being tormented. He is fastidious in strange ways, but has no qualms about shaking hands with jam-covered fingers. He is not hyperactive; rather, he is on the quiet side.
