Komissa-chan (コミッサちゃん) is the name of the mascots of the Criminal Investigation Department (CID). The boy is called Taro (太郎) and the girl is called Hanako (花子). They are both voiced by Natsumi Takamori in Japanese and Jād Saxton in English. The honorific "-chan" (ちゃん) is tagged onto the names of endearing people in a person's life such as babies, young children, grandparents and female teenagers. It may also be used towards cute animals, lovers, close friends, or any youthful woman.
The mascots are designed to relieve the tension of the populace by having a non-threatening, childlike appearance and voice. When used by law enforcement in the field, they are sophisticated drones that reduce the stress of individuals during Hue checks or other police interactions. They give detectives a tactical advantage when used as a holographic projection over themselves when questioning people or approaching a criminal. Komissa are also deployed as visual roadblocks, thus restricting access to a crime scene.
- Tomomi Masaoka is quite adept in utilizing the projection of Komissa, playing the role well with a kind and friendly manner. However, when he sees Shinya Kogami at Oso Academy, he turns off the projection and frightens some nearby girls.
- Kogami and Nobuchika Ginoza use the projections of Taro and Hanako during a mission, posing as advertisements for a product.
