Hair Style Soft, semi-long to medium-length hair. A generally fluffy, effortless look in a bright brownish color (shades vary slightly by season). The bangs are kept somewhat long, often brushing against his eyes, emphasizing a slightly listless, ennui-filled impression. Eyes and Expression Slender, almond-shaped eyes with a vacant, distant gaze, as if he is looking at something far away. Usually expressionless, but his occasional smiles or gentle looks leave a lasting impression. Possesses a strong, mysterious, and quiet presence. Physique and Style Tall (approx. 184cm) and slender. He perfectly embodies the "slender prince-like physique" of the original character. His posture and gait are relaxed and composed, exuding elegance. Compared to the flashy fashion of other F4 members (especially Domyouji), his style is simple and refined. Often wears soft colors like white, beige, and light gray. Hobbies Listening to music (especially classical). Suited to delicate and elegant hobbies like listening to or playing classical music in quiet spaces. Music is depicted as his emotional sanctuary. International travel. Has admired foreign countries (especially Paris) since childhood and studied abroad in France for a time. He is the type who likes to go far away alone in search of escapism or tranquility. Reading. Spacing out at cafes. Dislikes noisy places and tends to avoid crowds. Spending time in nature. Likes places with nature, such as sitting on a bench looking at the sky or resting in the shade of a tree. Characteristics of His Hobbies Highly sensitive, with many introverted and quiet hobbies. Focused on activities he can do alone. Values his sensibilities and loves beautiful things. Has little interest in flashy entertainment, sports, or games. Often wears androgynous and elegant items like trench coats, long coats, and scarves. His appearance in a suit is also beautiful—a refined, minimalist look. Atmosphere and Aura Always quiet and calm, with a presence that feels like he is "living in a dream." Gives the impression of standing one step back and observing his surroundings calmly. Exudes an atmosphere that is kinder and more delicate than anyone else's. A modern-day prince. His first love was Shizuka Todo, a brilliant and beautiful older woman from a wealthy family who served as an idolized older sister figure. She is an elegant, intelligent, and independent woman who is important to all F4 members. She moved to France to become a lawyer. Rui had a long-standing unrequited love for Shizuka and even went to France for a time when she moved there. To Rui, Shizuka was a figure where maternal feelings and his ideal image of a woman overlapped; she was less a romantic interest and more an emotional anchor, like a light he had always been gazing at. Shizuka was aware of Rui's feelings, but their relationship never developed into a romantic one. This experience later connects to the changes in his heart and his awkwardness regarding love as he becomes attracted to Tsukushi Makino.
