小関 桃子

Segawa Emi and Tenma Hasumi's classmate. Has tomboyish tastes, perhaps due to her brothers, who are much older than her. She always seems to be on top of things and lives for teasing Emi and Mihama Saki. Always up for some antics, and will generally join in if invited to do something. She's also known to drag others along for the ride with her. Loves Hasumi and can even identify the shampoo she usually uses by scent alone.

She became Shinkai Yuki's girlfriend in Youka Nanoka's short story Momoko After - PeachFlash.
