Yuusaki Kanon

Shion's younger sister.
She attends a school in the neighborhood and is in the same grade as Kyouko.

Occasionally, she helps out at the shop, and along with Shion, they are adored by the customers as the 'sister duo.
She is good at housework and does many household tasks in place of Shion when she is at the store. Although she appears reliable in front of others, she still has a somewhat dependent side, and when she is alone with Shion, she feels the urge to cling close.

She temporarily attended the music class that Shion used to go to, where she became good friends with Kyouko. She is a childhood friend of Nami, and often played together with Shion.
