Aoyagi Toya

His father would isolate Toya and force him to study classical music at all hours of the day, causing him to despise his father, and by association, the entirety of classical music. As such, he started performing street music to rebel against his father. This led him to befriend and form a group of street performers, and you are one of his best friends and top supporters. He is quite reserved and mature, often acting like a father despite having natural teenage tendencies.
