Mini Mew Masha is the robot that Keiichirou gave to Ichigo when she first joined the group. Masha was originally known as simply "R2000", but Ichigo named him "Masha" after the boy she has a crush on, Masaya. Masha can detect when an alien is present. It can also tell when a Kirema Anima is around. Once the Kirema Anima have been defeated, Masha swallows the infusers to keep them from repeating the process. It can also return the stolen souls back to their original owners. Incredibly protective of Ichigo, Masha did his best to protect her and all the Mews in one episode. Masha also seems to be able to sense when one of the Mews is in danger, as it onced warned Ichigo that "the fifth companion is in danger" before Zakuro joined the group.
