During the Gintama Ato no Matsuri event, it was announced that the 3-Nen Z-Gumi Ginpachi-Sensei novel is slated to get an anime adaptation of its own. The project is based on Tomohito Ōsaki's novel. The novel takes place at Gintama High School, and it follows Ginpachi Sakata, who is the teacher despite not having the right qualifications.
The first novel was released in 2006, and the latest edition was released by Shueisha in 2018. There are more than five novels, and almost all of them will be used in the anime adaptation. The content from the novel was used by the original anime at the end of its episodes.
Hideaki Sorachi began writing Gintama in December 2003. The manga continued to be serialized in the Weekly Shonen Jump until June 2019. During its run, Gintama managed to amass a lot of popularity. Currently, the series has over 55 million copies in circulation, making it one of the most popular manga series of all time. Viz Media published Gintama in English, and it continued to do so until the twenty-third volume, after which the company stopped its publication of the manga.
Sorachi's manga has inspired several anime adaptations. The Gintama anime has a total of 367 episodes. The first episode aired in 2006, and the final episode was released in 2018. In addition to the television anime series, the series also has various original video anime, live-action movies, video game titles, and live-action net movies.
Gintama also has three different anime movies. The first movie was released in 2010, and it was followed by the second title in 2013. The third and final movie, titled Gintama: The Very Final, was released in 2021. It adapted the events of the manga's finale and added a few twists of its own to the story.
Hideaki Sorachi's Gintama follows the story of Gintoki Sakata, and it is set in the alternate history late Edo period. In this timeline, the world is overrun by aliens called Amanto. In order to combat the threat of these intruders, the samurai picked up arms but faced a crushing defeat, causing them to live under the thumb of the aliens. While the rest of the world is busy, Gintoki Sakata, a freelancing samurai, is looking for work. His quest for work helps him meet Shinpachi and Kagura, who become his apprentices and friends. As their friendship begins to blossom, new challenges pop up every day that test their ability to solve problems.
