Sora
Sora is a junior high school girl who works part-time at angel 24 convenience store on the first floor of SCHALE building. She started working there almost the same time when sensei is assigned at SCHALE.
She's a little scared and not very good at talking to people but still tries her best to serve customers!
Perhaps because the convenience store is rarely used by anyone other then sensei, she can be seen looking bored aa she uses her smartphone.
