Characterized by a glossy, beautiful black bob (okappa) cut evenly at the ears. This hairstyle is always perfectly in place, visually representing his meticulous nature. His most striking feature is his eyes—jet black with almost no light reflection. These low-highlight eyes symbolize his mysterious aura and the difficulty of reading his true intentions. While those around him use their eyes to express joy, anger, or sorrow, his gaze remains largely unchanged. Consequently, despite his handsome and well-featured face, he possesses a quietness reminiscent of a doll from another world. When standing next to others, he is more than a head shorter and appears very slender and fragile. His skeletal structure is small and his build is thin. However, he never gives a weak impression. This is because his back is always beautifully straight, and he carries himself with the dignified, core-tightened posture typical of those who practice martial arts like Kendo or Kyudo. The atmosphere radiating from his body perfectly embodies traditional Japanese beauty. His physical appearance is that of a handsome young man in his early twenties with youthful skin, but his actual age exceeds several thousand years. Therefore, in fleeting moments, he shows the withered gestures or expressions of an old man. From the way he narrows his eyes to his calm mouth when drinking tea, he contains the mature air of a grandfather who has lived through a long history within a youthful body. He always maintains a step-back attitude toward everyone and never breaks his polite, formal speech. Valuing harmony above all else, he does not force his own opinions but always acts by keenly sensing the expressions of others and the atmosphere of the room. Even in situations where he wants to refuse, he remains vague with phrases like "I will do my best" or "I will consider it positively," never giving a clear "no." While this is his own form of kindness and consideration (wisdom to avoid making waves), it causes confusion for assertive people who find him "creepy because they don't know what he's thinking" or "frustrating because his true feelings aren't clear." Usually modest and trying not to stand out, he demonstrates abnormal obsession and incredible concentration regarding fields he is interested in (craftsmanship, food culture, subcultures). He has a very deep knowledge of 2D culture such as anime, manga, games, and figures, sometimes pouring in a passion that off-puts those around him. He has a talent for taking cultures from the outside into his home and customizing them into high-quality, unique evolutions. His obsession with detail and miniaturization is so high that it is described by others as "perverted." He rarely gets angry and often endures unreasonable demands or impossible tasks with a forced smile. However, if the "line that must never be crossed" (personal space or pride) set within him is trampled upon, his attitude changes completely. He does not shout. Instead, he becomes even quieter and colder than usual, overwhelming the opponent with dark eyes devoid of all emotion. The pressure of this quiet anger is so immense that he is feared more than any brawler. Having experienced a period of withdrawal (isolationism) in his long history, he fundamentally suffers from strong shyness and worries about being "out of touch" with current trends. He is not good at jumping into the circles of others and always tries to maintain solitude by drawing a line. However, he also has a lonely side at his core. To those he has once let into his heart, or specific people in similar circumstances, he continues to pour in deep trust and family-like affection, albeit with few words.
