Gintama: The Final Chapter - Be Forever Yorozuya

After catching a movie pirate at a premiere, Gintoki reviews the stolen footage and suddenly finds himself in a grim, ruined version of Edo-five years in the future. A deadly outbreak called the "White Plague" has wiped out much of the population, and the supposed pirate was actually an android time machine. To his shock, his Yorozuya partners, Shinpachi and Kagura, have grown apart and now fight alone as hardened vigilantes, while he vanished years ago, leaving only a cryptic note behind. Disguised with help from the android, Gintoki clumsily reassembles his old team to uncover the truth behind the White Plague. As they dig deeper, he realizes the answer to saving this bleak future is tied to his own shadowy history. Facing a formidable enemy, he learns one crucial lesson: with his mismatched group of friends backing him up, he doesn’t have to stand alone.
