Momo is generally an upbeat, easy-going, and friendly girl. Normally kind, but her rare bouts of anger can appear rather menacing. She has brown eyes and wears a standard shihakushō, with her black hair pulled into a bun held in a tied cloth. She has a love for reading and drawing. Momo also has a great bond with Toshiro Hitsugaya, the 10th division's captain. While serving as his lieutenant, Momo greatly respects and admires Aizen, to the point of idolizing him.
