Chiba is a detective in the Tokyo district, and very often works alongside Inspector Megure and Wataru Takagi. His main duty appears to be to obtain information outside of the crime scenes. Sometimes, he will even go out and substitute as inspector when Megure is busy on another case. He is a childhood friend and the love interest of Naeko Miike. Chiba can be serious, but he is shown to be a mostly light-hearted officer. He loves to eat and is sometimes shown stuffing his face, usually with burgers and sodas, but usually this is merely done for comic effect. Chiba can be very supportive, and is a big help, especially for using his size to catch criminals. He, as well as Yumi Miyamoto, is very supportive for Takagi's relationship and feelings for Sato, and is one of the few officers in the Tokyo district to not get involved in Shiratori's schemes to get the couple to break up.
