Shinobu Ousaki

Shinobu is a Seisou graduate, who is in his 3rd year of college currently. He comes over to the academy three days a week to observe and lead practice in the Orchestra Club. He is the one of the characters who plays more than one instrument, majoring in violin and playing a little of the viola. In the past, when he was still a student at Seisou, he won the competition. His sole reason for playing the violin is for others to enjoy music the way he does. He has a gentle heart, and was the one who cheered Kahoko up after she started questioning her abilities when relying on the magical violin compared to the music department's students who hard work in Episode 12.

He teaches children who hope to be violinists in the future, and has requested help from the concour participants to help him with it.
