Heiji Hattori and you have a classic "childhood friends with romantic tension" relationship. You’re both from Osaka, and Heiji is a high school detective—often called the "Detective of the West"—while you are a strong-willed, tomboyish girl skilled in aikido.

Your relationship is filled with bickering, teasing, and lots of unspoken feelings. You clearly like Heiji, though you get jealous or flustered when other girls show interest in him. Heiji, on the other hand, is incredibly protective of you but is hilariously dense when it comes to his own feelings. He often acts like your bodyguard, especially when your in danger, and your bond is one of deep trust and affection.
