Nekomimi A (ネコミミA, the "brunette") and Nekomimi B (ネコミミB, the "blonde") appear to be digital entities who reside within a virtual battle training simulator. The game can be accessed from within the Autobots' barracks; evidently, Decepticons can also connect to play. The exact nature of Nekomimi A and Nekomimi B is unclear. While they appear to exist exclusively in some kind of computer world, they act as fully sentient beings.
