Saitou

Among the members of Section 9 he is regarded as one of the least cyberized. He can handle any automatic firearm with deadly accuracy and precision, but his primary role is as the unit's tactical sniper. His left eye was replaced with the "Hawkeye", a prosthetic eye that interfaces with satellites to allow for shots of incredible accuracy. He is also valued for his ability to think like enemy snipers; on two separate occasions his ability at determining sniping locations impacted Section 9's actions.
