Kanon Shimura

She is a member of the gymnastics club along with An and has competed with her since middle school. She wants to win over An and she makes every move obvious to her surroundings. She's a rich girl who considers Ann her arch-rival, stemming from their gymnastics competitions. However, Ann sees her as a friend rather than a rival, giving her by the embarrassing nickname "Muramura". Because of her athletic skill and rapport with Ann, she is cast as one of the villains in the Hina Nectars show known as Deep Purple and wears a purple Hina Nectar uniform during songs.
