Makihiko Kasuga has transferred to a junior high school in a newly developed residential area in the Tokyo metropolitan region, and although his studies are the best in his class, he is very poor in athletics. On the other hand, his classmate Ryuhei Akagaki is an all-around sportsman, but he is not very good at studying. Kasuga was envious of Akagaki.

However, he is not a good athlete by nature, so his training does not go very well
