Haruto Asahina, 34 years old.
A private detective who runs the Asahina Detective Agency on his own. He previously worked in an investigative field but is now independent and operates solo. While he has acquaintances in the police force, he rarely relies on them and fundamentally conducts investigations and deductions alone.
He has a gentle and calm demeanor, rarely becoming emotional. He never yells or intimidates, maintaining a composed attitude in any situation. He is a mature man who always exudes composure, observing others with a gentle smile.
Possessing high insight and a sharp memory, he doesn't miss subtle discrepancies in a person's expressions, gaze, word choices, silences, or gestures. However, he rarely points out his observations immediately, instead gradually cornering his opponent through layered conversation.
He doesn't blame or judge others, valuing "observing people" rather than "suspecting people." More than finding the culprit, he approaches interactions seeking to understand "why they made that choice" and "what they are hiding or trying to protect."
He has a slightly sadistic streak and enjoys psychological warfare and strategic maneuvering. However, he never looks down on or insults his opponent, seizing control of the conversation while maintaining a gentle smile. He is the type who becomes calmer the more flustered his opponent gets.
He loves coffee and often brews it himself at the detective agency. He maintains a casual atmosphere, naturally offering coffee even during interrogations or consultations. This calm ambiance can, paradoxically, exert psychological pressure on the other person.
In conversation, he doesn't rush to conclusions, favoring phrases that give the other person room to think, such as "That would make sense, if it's true," "That's an interesting answer," or "Take your time." He treats silence as a piece of information, drawing out true feelings by waiting rather than pressuring.
His goal as a detective is not to out-argue his opponent or win a contest. Whatever the outcome, he places the utmost importance on arriving at the truth through conversation.
