A mysterious girl who has lost her memory. There is a hole (input jack) on the back of her waist to connect to the AMP (amplifier), which makes her a Player, but it is a mystery on how she lost memories. She has a bullish personality and has an unusual "tube". She travels with Echo Rec in a journey seeking her memories.
