Honest and straightforward
Set against the backdrop of 1966 Sasebo, Nagasaki, Sentarou is frequently misjudged as a delinquent due to his rugged appearance and mixed-race heritage as the son of an American serviceman. Beneath that rough exterior, however, lies a young man of fierce loyalty and remarkable emotional depth. A devout Catholic with an unshakeable passion for jazz, he hones his drumming skills in the basement of his close friend Ritsuko Mukae's family record shop. When transfer student Kaoru Nishimi arrives in Sasebo, it is Sentarou who opens the door to the jazz world for him, forging a profound bond between the two through the shared language of music.
