Hideaki Sorachi’s Gintama will never truly end, and that’s evidenced further through the reveal of a brand new anime film. There aren’t too many details at the moment, but the official website has confirmed that the next feature film project is currently in the works.
This third anime film will follow the acts of 2010’s Gintama: The Movie and 2013’s Gintama: The Movie: The Final Chapter: Be Forever Yorozuya. As far as plot, characters, and release plans, we’ll just have to wait for more details.
