Class is in session—and it's out of control! Sakata Ginpachi teaches Gintama High School's Class 3-Z, a ragtag bunch of idol otaku, stalkers, mayo guzzlers, sadists, and more. Fights break out, rules are ignored, and sanity is optional. Every day spirals into chaos, but Ginpachi somehow survives it all with nonchalance and almost zero effort. When the bell rings, chaos begins!
