It was officially announced at the recent Gintama Ato no Matsuri 2023 held at the Ryogoku Kokugikan National Sumo Arena that the parody spin-off work 3-nen Z-gumi Ginpachi-sensei ("Class 3-Z's Teacher Ginpachi"), derived from the classic manga Gintama created by Hideaki Sorachi, will be adapted into a TV anime.

At the same time, this year marks the 20th anniversary of the Gintama manga series, with only three years left until the 20th anniversary of the anime adaptation in 2006. It was also announced that plenty of anniversary commemorative projects for the Gintama series are set to take place during the next three years.

3-nen Z-gumi Ginpachi-sensei is a spin-off series based on the Gintama manga by Hideaki Sorachi, featuring the same characters as the original series. However, the setting is in the Gintama High School, where the story follows Ginpachi Sakata, who is dressed in a ragged white robe, has dead-fish eyes, and whose personality and appearance are not suited to be a high school teacher. He is teaching a class full of unique and strong-willed students, making the class seems like a terrifying theme park.
