The 3-Nen Z-Gumi Ginpachi-Sensei spinoff, first introduced in 2006, follows the comedic misadventures of Ginpachi as a teacher, despite his unconventional attitude. The novel series saw its latest volume published in 2018. This isn’t the first time the concept has been animated, as it previously appeared in short segments during Gintama anime episodes.

Gintama, which began as a manga in 2003 and concluded in 2019 with over 55 million copies sold, has inspired numerous adaptations, including TV series, films, OVAs, and live-action productions. The latest film, Gintama THE VERY FINAL, was released in 2021, and the franchise continues to celebrate its 20th anniversary with special screenings of compilations such as Gintama on Theater 2D.
