Sentaro is a wild 1st-year high school student who meets incoming student Kaoru at Higashi High School. Sentaro is mistakenly thought of as a thug by his peers, who fear him. Though tall and gifted with prodigious physical strength, Sentaro is also straightforward and bighearted. He's the exact opposite of Kaoru, yet somehow they hit it off when Sentaro starts to share his boundless love for jazz. The drums are Sentaro's instrument of choice.
