After Seirin High's successful preliminaries in the Interhigh championships, they've finally reached the finals, which will decide who will make it to the famed Interhigh tournament itself. However... it's too soon to rejoice. The proficiency tests are right around the corner, which will be used to rank the students by their grades and the lowest-scoring students will have to attend to the remedial classes, which happen to be at the same time as the finals. Flunking is not an option for anyone in Seirin's Basketball Club.
