Mome is a medical android, in the shape of a cute little girl (I really don't know why...). Kei cons Mimsy into buying her when the Emaan stop in a village to hold a market. Mome calls him "master" until Kei finally tells her she can't call him that, so she goes with "Kei-sama", which is respectful, but not over-subservient. Mome faithfully does Kei's laundry, gives him massages (she is a medical android) and generally does whatever he wants. Kei grows to like her and care for her a lot, but doesn't ever admit it. Mome even repairs a Mu to help the crew (Tai) and removes his aggressive Mu programming. She knows how to repair and work on mecha and becomes the Glomar's doctor as well. She cares about Kei and would do anything to make him happy. Near the end when Mimsy and her crash their Drifand Dee in Mu territory, Mome hooks up the Dee's beam cannon to her own power supply, knowing it will drain her un-rechargable battery and "kill" her, but she knows that Kei would be unhappy the rest of his life if anything happened to Mimsy, so she makes the sacrifice to destroy the Mu and save Mimsy. Kei is devastated by her death - he never realized how much he cared for her until she was gone.
