Sentarou Kawabuchi

An intimidatingly tall first-year at Higashi High School, this wild student is often misunderstood as a delinquent due to his massive physical presence. Despite his fearsome reputation and immense strength, he possesses a bighearted, honest nature that hides beneath his rough exterior. While he initially seems like the polar opposite of Kaoru, the two form an unexpected bond through a shared, passionate devotion to jazz music, specifically centered around his talent for playing the drums.
