Ukatan

Ukatan is a rabbit robot owned by one of the Adapter Girls, Perrier. Uka-Chan (full name UKATAN 09203) has a battery inside of his tail that frequently gets unplugged causing him to power off, until Perrier shoves his tail back in to restore his power. He also has a tendency to switch back and forth between two voices, a cute one, fitting of a mascot (voice: Kiyoshi Kobayashi), and a manly one (voice: Tomoko Kaneda). He is a valuable ally to the girls, with his ability to analyze any phenomenon they encounter (as long as he's not in the middle of turning off yet again).

The OVA seems to suggest that Ukatan and Perrier have a deep connection, because both him and Perrier have comparable split personalities. Unlike Perrier's alternate personality which is violent, Ukatan seems harmless in both of his personalities, except for when Perrier’s parents implanted him with an evil chip, though the girls were able to break the chip and return Ukatan to normal.
