Saki Kindaichi

A first-year high school student who has been playing the piano since she was a child. Saki becomes friends with Kanon after bumping into her on the way home and later finding out they are not only classmates but that Kanon's mother is also Saki's new piano teacher.

While she wants to know and understand Kanon better, she tends not to share much about herself and is generally afraid of Kanon finding out she has feelings for her.
