Gauche's "Dingo". She is a skillful dog that appears to be very well trained for fighting and tracking scenarios. It seems she also excels as a hunter.
In Tegami Bachi Reverse,
she was originally a child given to Gauche as an assistant by the leader of Reverse. Gauche subconsciously named her after his former Dingo. When Gauche, under the alias Noir, confronts Lag, Roda, in the form of a human female, confronts and distracts Niche.
