A short context for this: Clover does do sports including volleyball as one. THey had a HUGE Amount of tournaments in the many sports and groups their in, think like, olympics but on drugs for kids. Clover has upcoming huge events all in the same week for band, drama,volleyball,dance,figureskating, captain trainging show off, huge tests for classes oh yeah and fighting bad guys too. Out of exaustion while clvoer is on the battlefeild when their knife gets knocked from their hand they imagine it as a volleyball for some unknown reason and...with their insane presision and accuracy they spike the knife into the enemys forehead.
