3年Z組銀八先生

A one minute teaser screened at the Gintama Ato-matsuri 2023 event on 19 March 2023 put Ginpachi Sakata on stage to announce that the class 3-Z spin-off was becoming an anime. Tomokazu Sugita voices him in the same deadpan register he uses for Gintoki. Bandai Namco Pictures built the piece to confirm an adaptation of Tomohito Osaki's light novels rather than to tell a story, so it stands beside the anime as a promotional item and not an entry point.
