Shiu

Shiu stands as the most experienced veteran at the legally operating interrogation firm 'Water of Life,' a status that has earned him legendary recognition across the industry. Known for his understated, composed demeanor, he is rarely seen without a cigarette in hand. His right eye is a prosthetic, kept hidden beneath his bangs.
