Despite receiving single-digit scores on his tests, Oota smirks and seeks out new forms of entertainment. His attention is soon caught by Kashiwada, a classmate who always maintains a blank expression. Oota makes it his mission to stir up some emotion in her through pranks and scares, but his attempts always fail.
