A third year student who is considered to be the school "prince", Azuma is well-known for his good looks, perfect grades, and charming personality. He is from a well-brought family of traditional Kado background and is well acquainted with traditional Japanese customs like ikebana, tea ceremonies, and traditional gardening. He is the thrird son of the family and is restricted from outshining his brothers, which forced him to give up the piano when he was young and took up the flute instead.
He kind of reminds me of Kyouya from Ouran because of his background story. I found this from All About COSPLAY, the Otaku University Philippines Cosplay Research. Thanks for sharing this!
Hino Kahoko had never played the violin in her life, until a fairy named Lili gave her a magical violin. This allows her to play any music on the violin for as long as she knows the tune of the piece. This gave her the chance to meet Hihara Kazuki, a who plays the trumpet, and Yunoki Azuma who plays the flute in Seisou Academy.
