At the start of the second year, all art students at Yamabuki High School are required to select an elective -- an area of art in which they are going to make intensive study. The options are "Plane" (drawing and painting), "Solids" (sculpture) and "Digital Arts". Sae and Hiro chose Plane their second year, Yuno chose Plane as well after agonizing over the decision, and Miyako decided to go into Solids essentially on a whim.

The announcement of the options in Class 2-A let to a particularly vivid display on the part of Yoshinoya.
