This might be based on some biases, so please don't get mad... these are characters from a police documentary show.
Name: Igara Affiliation: Metropolitan Police Department. A police officer who frequently handles traffic violations. He has decent physical strength and is quite intelligent. He is serious and kind, though perhaps a bit clumsy. He generally uses polite speech with civilians, but uses softer, casual forms like "I wonder..." or "Right?" with children or people he is close to. Surprisingly, he loves extremely spicy food—so much so that it weirds others out. First person: I (Watashi, occasionally Ore) Second person: you (Kimi) / [Name] without honorifics Third person: you all (Kimi-tachi), etc.
Affiliation: Metropolitan Police Department, like Igara. He once attempted a raid on a yakuza office, which proved difficult and took 8 hours. His attitude then was polite, saying things like "Please open up, we have something to discuss." Despite being in the Organized Crime Department (Marubou), he is physically weak. He has a slightly light, casual way of speaking, using slang like "Isn't it?" or "Seriously?" He likes sweet and spicy food (but can't handle extreme heat). First person: I (Boku, occasionally Ore) Second person: [Name] without honorifics / you (Kimi) / [Name]-san Third person: you (Omae), etc.
Name: Asakura Affiliation: Saitama Prefectural Police. He was once terrified by the intensity of a raid conducted by Osaka police officers visiting Saitama. He plays the "straight man" (tsukkomi) and is likely the most sensible person in the group. He's a bit of a tsundere, using rougher casual speech like "Don't you...?" or "It's not..." When being polite, he uses forms like "Isn't it?" or "...sir/ma'am." He loves gummy candies. First person: I (Boku) Second person: you (Omae) / [Name]-san (for Yamato, Shiranui, etc.) / [Name] without honorifics Third person: you guys (Omae-ra), etc.
Name: Yamato Affiliation: Osaka Prefectural Police. He handles traffic violations and always has candy and gummies in his bag. Although not in the Organized Crime Department, he is capable of conducting raids. He is surprisingly kind and has a sweet tooth. During raids, he shouts things like "Open up already! This is Osaka!" or "Open the damn door!" Normally, he says things like "I'm checking the records, please show me your license." Speaks in a Kansai dialect. First person: I (Ore; uses Wai during raids) Second person: you (Anta) / [Name] without honorifics Third person: you all (Anta-ra)
Name: Shiranui Affiliation: Osaka Prefectural Police. A member of the Organized Crime Department and a pro at raids. He always has snacks in his pockets. Once, when it snowed (a rarity), he got into a snowball fight with Yamato during duty; Asakura and Katagiri scolded them severely, leaving him looking totally dejected. He has a severe sweet tooth. During raids, he's menacing: "Hey! You! Open up!" Otherwise, he's calm, saying "Well, let's go" in a Kansai dialect. First person: I (Wai) Second person: [Name] without honorifics / you (Omae) / (Always uses 'Teme' during raids) Third person: you guys (Omae-ra) / you all (Anta-ra) / you bastards (Teme-ra)
