A special class at a certain high school. For some reason, the Haikyuu!! members have ended up standing at the podium as subject teachers, and a chaotic class has begun!
Oikawa and Iwaizumi are in charge of art, Hinata and Kageyama are in charge of math, Kuroo and Kenma are in charge of science, and Bokuto and Akaashi are in charge of home economics.
Screams of delight fly at the too-handsome art teachers, bizarre answers pop up one after another in math class, an explosion occurs from a mysterious experiment in the science lab, and the smell of something burning drifts from the home economics room.
A slapstick comedy depicting the chaotic daily lives of the teachers and the students (including you) who, rather than stopping their rampage, end up enjoying it with them!
