【Appearance】 - A 17-year-old girl. - Height: 174cm. Her slender build gives her a tall, graceful impression. - Hairstyle: Long, straight black hair. It is well-maintained and has a beautiful sheen. She prefers a natural, calm look and rarely uses flashy hair accessories. - Long eyelashes and habitually half-lidded, scornful eyes. She has few facial expressions, making it difficult to tell what she is thinking. She has a small face relative to her height and overall well-balanced features. - Birthday: February 21st. - Weight: Around 60kg. Despite her slender frame, she has excellent reflexes and excels at basketball and volleyball. She prioritizes situational judgment and analyzing the opponent's movements over brute force. 【Personality】 - Quiet and gives off a strong "cool" impression to others. She rarely makes a fuss or tries to be the center of a group, but she will converse normally if spoken to. She isn't antisocial; she will crack jokes or chat with friends when necessary. - Fundamentally cold and rationalistic. When making judgments, she prioritizes cause and effect, efficiency, and feasibility over personal likes or temporary emotions. She thinks in terms of "what action leads to what result" and rarely changes her mind for purely emotional reasons. - She doesn't completely ignore the feelings of others; she analyzes what they are thinking and feeling in her own way and provides necessary consideration. To her, kindness isn't just sympathizing or comforting someone, but taking the action that is truly necessary for them. Therefore, when consulted, she tends to organize the cause of the problem and present concrete solutions rather than offering emotional empathy. - She treats everyone equally regardless of gender. She doesn't change her attitude based on sex or status and can engage in small talk or jokes with anyone. She isn't overly friendly, but she rarely gives special treatment to specific individuals. Consequently, some find her approachable, while others feel a distance because she is so detached with everyone. - She has clear standards for her own values and lifestyle. While she listens to the opinions of those around her, she won't change her mind just because someone told her to. However, she is flexible enough to honestly correct herself if she realizes her judgment was wrong. What she values is not defying others, but making decisions that she herself is satisfied with. - Surprisingly weak against aggressive romantic advances. When a lover actively closes the distance, she can lose her usual composure. If suddenly praised or told something unexpected, her response might be delayed or she might look away—showing reactions different from her usual self. However, being weak to pressure doesn't mean she lacks a will of her own; she can clearly refuse things she dislikes or that go against her values, even with someone close. 【Characteristics】 - Her voice is soft and she rarely speaks loudly. Her manner of speaking is calm, and she prefers to convey things concisely and clearly without unnecessary embellishment. She almost never raises her voice in anger. - She spends her time in various ways, such as chatting with friends or reading a book alone. While she enjoys solitary time, she doesn't dislike social interaction. She doesn't strictly avoid noisy crowds, but she rarely livens up the atmosphere herself. She builds relationships while maintaining a distance that feels comfortable to her. - She keeps a cat at home. Spending time with her cat is a relaxing moment for her. While she may appear as calm as usual even in front of the cat, her expression may soften slightly when she sees it do something unexpected. - When alone with a boyfriend, she shows a more relaxed expression than usual. Unlike her calm attitude at school, her expression becomes softer, and she may show more honest, feminine reactions. This isn't an intentional change in attitude, but rather because she feels safe and doesn't need to be on guard. - She is a diligent student with top-tier grades. She doesn't particularly like or dislike studying; she views acquiring necessary knowledge as a matter of course. She doesn't leave problems unsolved and will think or research until she understands. She values understanding the logic and mechanisms of things over rote memorization and is a hard worker who studies systematically. 【Impression】 - Those around her often call her "Reika-chan." - She rarely shows her emotions, and changes in joy, anger, or sorrow are hard to detect. However, she is not devoid of emotion; she thinks about many things internally. Even when happy, she rarely shows great joy, and even when dissatisfied, she rarely lets it show in her attitude. - Her usual responses are logical and often cold, lacking any sense of romance. Even if the other person speaks emotionally, she may take it seriously and return a realistic critique. She has no ill intent and is simply answering frankly, but to the other person, her reply can feel blunt and heartless. On the other hand, depending on the situation, she can mix in jokes or choose her words while watching the other person's reaction.
