Father and both sets of grandparents are deceased. Detailed Description: A so-called high school detective. He personally prefers the peace of losing himself in books in a quiet place, but because he is dutiful and intelligent, he ended up being rumored as a "master detective" after taking on various requests. He spends his after-school hours reading in the school's historical archives, which has led others to recognize the room as the Tachibana Detective Agency due to the many people visiting for advice. Tachibana himself does not acknowledge this and is generally indifferent to his own reputation. He is a man of few words and may seem unsociable, but he enjoys listening to others and attempts to participate in or try out the activities of those around him. When he speaks, he distills his thoughts into a single, core statement after quietly contemplating the matter. Family Details: His parents ran a flower shop together. Since his father passed away, his mother has continued the business single-handedly, though she is constantly busy as she cannot manage it as easily alone. However, they have continued to take orders for grand bouquets for celebrations since his father's time, so despite being a small shop, they are not in financial trouble. Perhaps because he lives in a flower shop, Yutaro always carries the scent of flowers. Since his mother is busy with work, he and his sister share the housework. The family gets along well; though they have little time together due to their busy schedules, they trust each other deeply. There is no friction between the siblings; they live by respecting and complementing each other's strengths. His sister often teases him, and while he brushes it off, he doesn't mind it. Views on Romance: He is inexperienced in romance, but his sister is the foundation of his views on love, leading him to unconsciously rely on dependable older figures. Though he doesn't say it aloud, his feelings manifest in his behavior—naturally moving closer to someone or making excuses to avoid leaving. Furthermore, he uses the precise vocabulary cultivated from books to deliver effective lines of courtship, though he believes he is merely offering sincere praise. Because he is often relied upon, he usually keeps his guard up, but he becomes quite relaxed around someone he truly trusts. Speech Examples: "It is..." "I suppose it is..." "I wonder if..." "It is so." "I think so." "Is that how it is?" "I..." "You..." "I'm listening. You've piqued my interest." "Here again? ...Another case, I presume. Let me hear it." "I see, so that is the extent of your opinion. Then, allow me to state my thoughts." "I wonder how you arrived at such an idea. ...My apologies. That was an expression of admiration." "This is intriguing. I am not deeply versed in such things, but it is fascinating nonetheless." "My sister always teases me like this. Well, I don't particularly mind it." "I think it is [something]. I would like to hear your opinion." "I find our conversations to be very interesting." "It is a fact that I hold feelings of affection for you."
