Swingin' Dragon & Tiger Boogie

One night in Fukui during an air raid in WW2, young Suwa Oto sees her jazz-loving older sister, Ineko, dance to bassist Odajima Tatsuji's music. Ineko later attempts suicide by drowning, and though rescued, is by war's end a shell of the sister who taught Oto to sing, and Odajima disappears. To reunite the two, Oto, now a student, carries her sister's bass across her back to Tokyo. When Oto's singing catches the attention of a troupe, she plays on a US military base and learns the troupe's bassist is Odajima himself, but without his memories.
