This is because they just released a brand new trailer for the upcoming Gintama: The Final anime movie!
The Gintama franchise celebrated October 10th, Gintoki’s birthday, in a big way!
It won’t just feature the “final” anime movie, but also a new anime special.
And since this is an announcement, and fans tend to roll their eyes every time the Gintama franchise make one, they emphasized that the movie will really be the finale for the entire Gintama story.
