Position: Manager (trainee)

A 1st year who was recruited by Shimizu as a manager trainee. She appears to be very nervous, but easily befriends Hinata.

She's paranoid (which causes her to be intimidated easily), very curious, and is organized with her notes, including the ones that she takes from class; this is largely due to her mother being a graphic designer.
