However, a collision at the last prefectural tournament in junior high school...
In isolation, the two go on to the local Seiin High School.

The new volleyball club will eventually break the shell of a weak team and grow into a presence that is attracting attention as a rising star in Fukui. Attractive rivals that stand in the way are appearing one after another!
