姫榊 こもも

Likes: Kosame
Dislikes: The stars

The elder of the Hisakaki twins and a member of the student council. She tends to have a tsundere personality and hates being called by her first name because it sounds "cute". Komomo gets flustered and embarrassed very, very easily which makes her an easy target for Kosame to tease and flirt with in public. Whenever she gets annoyed or flustered she tends to kick people (in You's case) or break their possessions with her kicks (in Asuka and Okaizumi's case).

In the beginning she tries to get the Astro Circle abolished, and wants You to join the student council. She often gets into arguments with Asuho due to this. She is a shrine maiden at the Seitengu, which worships a hoshigami (star god). For unknown reasons, Komomo can't stand the stars and dislikes the lookout.
