His strict dad, a classical musician, had Toya take music classes for especially talented children from a young age. This early education brought results, but in an act of defiance against his father, Toya became a street musician.

Toya is quiet and calm but has a strong mind. His face is often deadpan, and people other than Akito and Tsukasa have difficulty reading his expressions. When people talk to him, they usually mistake him for being rude, as he is blunt and often misphrases his statements. Despite his stoic demeanor, he is kind and quick to help others. He can occasionally be airheaded or gullible.
