Momo's name is derived from the Jewel from the Dragon's Neck (龍の首の珠), the object in The Tale of the Bamboo Cutter that Ootomo no Miyuki (Miyuki's counterpart) had been tasked with collecting.
Momo is a girl of average height and light hair. She wears the standard Shuchi'in Academy girls uniform and usually has a hat on.
During her freshman year, her hair was was several inches longer.
As a member of a yakuza family, she places little value on the school rules, as seen by her wearing a hat and playing games on her cellphone while on school grounds. She also has a short temper, and others view her as being threatening.
Currently, she is the president of the Astronomy Club and makes a few appearances as a background character throughout the story. She was involved in helping Miyuki steal all the heart-shaped balloons during the Culture Festival.
