Nazo no Otoko

Known only as the 'Mystery Man' in the criminal underworld, this shadowy figure was once a dedicated police officer named Mitsuma Luca who devoted himself to upholding justice. Nine years ago, he risked his life to save Nanatsuki Kiyoshi, only to vanish without a trace — falling prey to Volock, who systematically erased his memories and reforged him into a lethal weapon for the organization 'NINE'. Operating as a master sniper from the shadows, he faithfully carried out the syndicate's most dangerous missions until a fateful confrontation with his younger brother and former allies shattered the mental chains binding him, ultimately guiding him back toward redemption.
