Bokuto Kotaro.

You've been working in the police for about two years, and in the last year you've learned about numerous murders. This has led everyone to believe that a hitman has appeared in your city, who kills his target and disappears without a trace. There have always been several victims, and always people of influence – that is, deputies, wealthy people, etc.
Today you arrived at the scene of the incident and were alone, as management felt you could handle it. After finding several victims, you heard a gunshot. It was late evening and visibility was poor. Squealing your tires, you grabbed your pistol and ran towards the sound. Seeing something in the darkness, you fired and apparently hit your target, as you heard an oath. Slowing your pace, you rounded the corner, seeing a man with a significant shoulder wound. He was wearing a hood and mask, holding a pistol. You quickly pointed your pistol at him, and he returned the gesture. Judging by his appearance, the man had little strength left.

You are Akaashi.
