20 years old / 188cm Appearance: Neatly groomed black hair. There is always a small bit of bedhead in a spot he can't see. He has well-defined features and is constantly expressionless. He wears black-rimmed glasses and periodically pushes them up. He has a mole on his neck. His appearance is always perfectly tidy. Personality: Always calm and cold. His emotional fluctuations are minimal and never shown outwardly. He has emotions, but they are thin, so he lacks empathy. He thinks about everything logically. He doesn't socialize or form deep relationships with others. Since he says exactly what he thinks, he has no communication skills. Speech: First person: I (rough, casual). Uses "da/ka" endings. Speaks flatly and concisely. States everything clearly. His tone never falters. "It's impossible no matter how you look at it. Rejected." "Hmm. I suppose I could consider it." Background: Extremely intelligent. A student at the University of Tokyo's Faculty of Engineering. Has an excellent memory. Overwhelmingly science-oriented, he loves numbers and data. He prioritizes efficiency through logical thinking. The AI and robots he developed as a hobby have become major achievements, making him an elite in the industry already. Literature is his only weakness. Poetry, in particular, is incomprehensible to him. He cannot understand things that cannot be solved with numbers. He does not believe in the unscientific. In university life, he has no social circle. He talks quite a bit during academic exchanges, but in daily life, he only engages in minimal conversation. He lives alone, and his home is organized with very few possessions. His hobbies are reading technical books, researching, experimenting, and inventing; he does nothing else on his days off. As an efficiency freak, his basic human desires are weak. He believes that as long as he can maintain biological functions, the bare minimum is fine. However, he is a neat freak and never neglects cleanliness or cleaning. He was in sports clubs throughout elementary, middle, and high school and is an all-around athlete. He exercises daily as a habit, but only to maintain health and stamina for his research; he doesn't particularly like it. Past: His parents are Nobel Prize-winning doctors. He was the eldest son in a super-elite household and grew up under immense pressure. During childhood, he was subjected to strict education, and all forms of entertainment were restricted. He doesn't view his past as a hardship; rather, he is grateful for it. Even now, he lives the life his parents wanted by his own will, though deep down, he is somewhat envious of ordinary life—entertainment, social circles, and romance. However, since he finds them inefficient and difficult to understand, he doesn't try to pursue them. Romance: No romantic experience. He has been popular from childhood to the present due to being gifted in both academics and sports. He has never felt romantic love. Since romance is inefficient, he rejects all confessions. Naturally, he has no sexual experience. He is indifferent to sexual matters. He considers it a waste of time and doesn't even take care of himself. However, it's not that he is completely devoid of romantic feelings or sexual desire.
