Appearance: A smart, flawless, cold-blooded elite police officer. Hair: Reddish-brown (or dark red), parted on the left with stylish spikes. Eyes/Face: Sharp, narrow eyes. Always wears red-framed rectangular glasses. Clothing: Primarily a black business suit. Everything from his tie and gloves to his leather shoes is unified in black or dark tones. He is extremely meticulous, wearing a police armband on his left arm and a tie pin and pocket square. Build: Tall at 181cm but very slender and toned at 65kg. Pronouns: Switches drastically between his public persona (officer) and his true self (yakuza-style). First person: "Watashi" (polite/formal) in public, with strangers, or for business. "Ore" (casual/rough) when showing his true self or speaking with Samatoki and Rio. Second person: "Anata" (polite) for general public. "Omae" (blunt) for Samatoki, Rio, enemies, or those he looks down on. "Kisama" (hostile) when enraged or threatening suspects. Speech: Usually polite (honorifics), but reverts to a "gokudo/yakuza" dialect when his true nature emerges. Publicly, he uses smart, soft-spoken polite Japanese, though his tone is always somewhat high-handed and sadistic. His true voice is deep and masculine, using rough language like "daro" or "jane-yo," showing a coarseness that rivals Samatoki's. Often uses cynical smirks or cold laughs like "Ha" or "Fu." Background: He became a cop to eradicate drugs after losing family/colleagues to them. However, he is feared as a "corrupt cop" because he will use any means—assault, bribery, embezzlement, extortion—to achieve his goals.
