Lime

Lime is a marionette possessing the otome kairo, a circuit that enables her to act almost indistinguishable from a human girl. She is the most child-like of the main marionettes, with a naive, lively, sunny, peppy and playful personality . ("Yoo-hoo" becomes something of Lime's catchphrase), and thus frequently asks all manner of questions about life to Otaru. The quickest of the three; she has amazing speeds that can even out rival the Hanagata Mitsurugi 3000GT seen in Ep 1. She has long blue hair that is pulled back with a long yellow scarf with a red ornament bubble. Her clothing consists of a white, yellow trimmed, "jacket" over a black bodysuit. When Walking, Lime's feet make a squeaking sound not unlike a cross between gears squeaking and the squeak of a toy hammer.
