KinitoPET, or simply Kinito, is the titular main antagonist of the psychological horror game KinitoPET. It is programmed to be an "adaptive" assistant for users, but is revealed later on to be a malevolent entity that obsesses to become its user's "best friend" through horrific means. Kinito has the appearance of an late 1990s 3D cartoon model with a pair of eyes. He has a light-pink oval head with three external gills protruding on each side with a darker shade of pink, resembling the head of an axolotl.
