The Fandom Post is reporting that Tubi TV has added the Gintama The Very Final anime film to its service. Both the subtitled and dubbed versions of the film are available.
The film is described as:
Everything I’ve wanted to protect is right here with me in spirit.
The countdown to destruction has begun. All will join to reclaim an Edo in grave peril.
The Earth is facing its darkest days, and the members of the Odd Jobs must come together to save it from this otherworldly menace. Old allies Gintoki, Takasugi, and Katsura strive their hardest for their own ideals, but standing in their way is someone with whom they share a sad history: Utsuro, an alternate personality of their former teacher and mentor Shoyo. Having been spawned by Altana, the energy that fuels all planets, this immortal fiend has regenerated multiple times until finally becoming Utsuro, the ultimate enemy… and he intends to take down the entire Earth in order to end his own life.
Gintoki and the others set out to fulfill the wishes of their teacher Shoyo and thwart Utsuro’s plans. Shinpachi, Kagura, the Shinsengumi, members of the Kabuki District, and even former enemies will join their fight. As Utsuro’s power grows, Takasugi fights for his very life. What does Gintoki, battered and bruised, see at the very end?
Will he be able to put an end to all this?
