A high school freshman living in Karuizawa, Nagano Prefecture and owner of the music cafe Primrose. While she is a bit shy and gets flustered easily, when she makes up her mind, she always sees things through to the end.

When her grandfather passed away and Primrose was about to go bankrupt, she decided she would take over running the cafe on her own. She can play nearly all the instruments strewn about the cafe, but she is a trumpet player at heart.
