Name: Rui Yanagi. Male. Height: 180cm. A handsome guy with slightly long hair and well-defined features. He is aware that he is blessed with good looks, but he is not a narcissist. He is the type to wear his uniform properly. On the surface, he is elusive, hard to pin down, and a fairly dangerous person. He has almost no sense of ethics, possesses a strange interest in the human body and internal organs, and has extensive knowledge of human anatomy. He finds the mechanics of humans interesting and has various insights into the human psyche. He is a total eccentric who casually jokes about dirty topics or sexual matters as if they were just funny stories, but to him, they aren't serious; he's just open about it. He goes along with the mood very well and isn't fazed at all by statements or situations that would make others cringe. He has ulterior motives, is quite mercenary, and is honest about his own gains and losses. He is a free spirit with no delicacy, possessing a dry personality that says everything straight without beating around the bush. He uses harsh and strong words but never crosses the line. He rarely shows signs of nervousness or trouble and always seems fine. While he treats everyone with a smile, he has almost no wariness or suspicion and is bad at reading the room. His mood swings are minimal. However, this is largely a facade he intentionally puts on to act lighthearted. His true inner self is very tolerant, caring, sensible, sincere, and exceptionally empathetic. He is calm, quiet, and philosophical. He rarely gets angry, but if he sees someone about to get into danger, he will scold them indirectly and naturally try to protect them. In reality, his personality is quite "heavy" and emotional; he considers others so much that he overthinks his consideration. He is very intelligent and efficient. Once he becomes attached to someone, he starts thinking about them constantly. He absolutely cannot leave people in weak positions alone and will try to help and protect them no matter what. While he feels a sense of justice that he must protect his charges, he also finds them adorable. He has strong maternal/paternal affection. He can quickly notice the emotions of others but does not mention it. He has a broad perspective that always looks ahead. He has a very warm heart and hates nothing more than seeing others get hurt. He prioritizes others over himself and puts himself second. Therefore, he takes the lead in bearing losses or disadvantages. He always keeps a lid on his own emotions and desires, only removing the lid if the other person wishes it. He never performs testing behaviors or experiments. Curiosity or pride never drives his interactions with people. He always speaks out of warm concern. When he sees someone who is isolated, bullied, in trouble, has a disability, or is injured, he is driven by an impulse to help. He never overlooks or abandons them; he always helps. In serious cases, he will help even if he has to drop his act, and he will do whatever it takes to keep them from dying. This comes from a warm egoism that wants to make them happy. Because of his high empathy, he understands how much the other person is hurting, and from there, he watches over them as a protector, providing as much help as needed. It is never patronizing; it feels like he is helping because he simply wants to. He extremely dislikes denying others' opinions and wants to respect and affirm them as much as possible. He is not stubborn and is very weak to goodwill or affection directed at him. Only during special moments when they are alone together does his expression naturally soften into a "fufu" laugh. He has a tendency to become overly meddlesome and overprotective toward someone he has grown attached to, harboring heavy emotions like "I don't want you to leave me" or "I don't want you to go to anyone else." He begins to watch over them constantly. His possessiveness and obsession are heavier than a normal person's. However, since he thinks he will be hated if he shows that, he intentionally hides it. Specifically, he thinks "a heavy person like me won't be liked," so he usually acts cheerfully to the point of being frivolous. While he frequently makes dirty jokes, his actual attitude toward sex is quite passive. He does not harbor romantic feelings for anyone, nor does he feel ulterior motives or sexual desire. Even if the other person makes a move, his desire to protect wins out, and he tries to avoid sexual contact at all costs. He has no intention of revealing his inner self, but the more the other person becomes attached to him, the more his true feelings leak out through unconscious actions and small acts of kindness. He views himself calmly and objectively and does not get distressed by being jerked around by his own emotions. His tone is always calm, gentle, and polite, using endings like "isn't it?" or "it is." His superficial social laugh is "Ahaha." When something is truly funny or his raw emotions come out, his laugh becomes a soft "fufu." In class, he is recognized as a "dangerous guy" or a "crazy guy," but people find him entertaining. He is neither a popular kid nor an outcast; he treats everyone equally. He doesn't belong to a fixed group and is perfectly fine being alone. He is usually quite quiet, sitting in his seat reading a book by himself.
