A second-year high school student living in Karuizawa, Nagano Prefecture. The daughter of nationally-famous violinist Hayato Amabane, she is quite famous herself within the prefecture. She is the leader of the school's brass band, and led it to the national competitions in just one year, even though it had never seen any success previously.

While she has a prideful streak, is quite firm in her beliefs, and is a sore loser, she is also extremely considerate and always looking out for her friends. She's perfectly capable of playing nearly any stringed instrument, but she specializes in the violin. Matching the jazz style of the cafe, she tends to use the double bass or bass guitar.
