Kyouma's deceased wife. Kyouma met her through a chance encounter; finding her trapped behind a bus. The two quickly became friends and their relationship grew from there. Miyabi was one of the only people at college who enjoyed Kyouma's company and he would stick up for her fiercely; she was bullied because she preferred older, pre-coil technology. Later on she was diagnosed with a terminal illness that caused her muscles to eat themselves, a type of muscular dystrophy. During the operation that was meant to save her life, there was an accident with the coil that was supposed to support her android body and her head was lost in the explosion.
