A math teacher at Tokise High and the Koto Club's advisor.
SpoilerInitially he feigned ignorance of his musical background, though it's later revealed that his parents are world renowned musicians. As a child, he had no interest in playing music whatsoever other than listening to it. When he was seven, his father discovered his talent for writing musical scores and quickly took upon him to brand his son as a child prodigy. Because of this, Suzuka began to disdain music but his interest is later revitalized after becoming the advisor for the Koto club. He often writes pieces for the club as well as gives practice advice, while leaving the actual koto teaching to Akira.
