Blue Giant

Dai Miyamoto is in his last year at senior high school. He plays in the basketball team, works part-time at a petrol station and lives alone with his father and younger sister. Above all, he has been a jazz enthusiast since he was in junior high school. So much so, he plays every day on the riverside whatever the weather is like.
Whether it's rainy, windy or scorching hot, he plays. He wants to become a jazz giant and is convinced he can do it. However, in order to succeed, he will have to face up to reality: Dai's determination will be put to the test by giving explanations to his friends, his first chaotic performances and the various people he meets.
