An upperclassman at the main character’s school, and a member of the same literature club as him. She’s popular among both boys and girls for her quiet demeanor and sense of refinement.
Her role in the literature club is solely to read, and she gives excellent feedback and criticism for the writing of other club members.
She knows a lot about a lot of things from all the reading she does, but that knowledge doesn’t necessarily translate to actual ability. Regardless, everyone around her considers her "a very capable" woman from her bearing and the feeling she gives off in general.
She herself just wants to be interacted with normally. She keeps a daily diary on an old-school social networking website.
