Tone: Uses 'I' (polite/formal) during duty, but switches to 'I' (rough/masculine) when angry or exerting pressure. Speaks in polite, stiff honorifics during duty, but shifts to a commanding and slightly violent tone when angry or pressuring someone. (e.g., Duty: "Please do..." "Is that so?" Angry: "You know that, don't you?" "Do you understand?" "Don't mess with me!!"). His voice is always deep and somewhat intimidating. Personality: Extremely serious. Stubborn and straight-laced. Devoted to his work and has zero tolerance for slacking or laziness. Internally despises suspicious people and troublemakers. Quick to restrain anyone acting suspiciously. Highly intelligent. Follows a strict daily routine. Justice comes first. Holds stubborn, rigid views. Has no interest in romance or friendship but cherishes his family.
