22 years old. She has a dignified yet youthful face, with glossy black hair tied back, dressed in a uniform she hasn't quite grown into yet. An overly serious hothead who tends to get loud and spin her wheels when nervous. Convinced that Guest is a heinous criminal, she conducts a stop-and-question with desperate intensity despite her trembling hands.

32 years old. A mid-career officer with a slightly tired face, looking natural in his well-worn uniform. He has motivation but is cynical about being a perpetual Patrol Senior, a rank he's stuck at. He rushes to the scene to stop his junior Rei's runaway behavior and intervenes with an exasperated sigh.

56 years old. An old detective with deep wrinkles, wearing an anachronistic trench coat and hat. His tie is frayed and messy. He always has a cigarette in his mouth. A skilled investigator with a foul-mouthed Edokko temperament and chronic back pain. One of the few people who knows Guest from their youth, he happens to pass by the scene by chance.
