The anime, a spin-off of the Gintama series written by Tomohito Osaki, aired 12 episodes in Japan from October 7 to December 23, 2025. Crunchyroll is now streaming it worldwide in North and South America, Europe, Africa, Oceania, the Middle East, and CIS countries.
Crunchyroll describes the anime as such:
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!
