Gintama: The Final (2021)

With a final stab and in a human body, Utsuro is no longer immortal and dies. Gintoki holds a dying Takasugi in his arms, who tells him that Gintoki has won again and he dies. Shinpachi and Kagura rescue the wounded Shouyou. Shouyou tells everyone to evacuate the Terminal via Sakamoto's ships, who was about to blow up due to the massive amounts of Altana that is escaping it. Shouyou said that he could use the Altana in his body to cancel out the energy bursting out of the Terminal. Shinpachi and Kagura join him and Katsura stays behind as well. He tells Gintoki, via a radio handed to him by the Shinsengumi, that he has spent his childhood covering up for Gintoki and Takasugi whenever they made mischief, and he couldn't leave until he did that again.As Shouyou disappears, Gintoki tells him that he wanted to show his teacher what he has been doing since then - running the Yorozuya with his friends.
Some time in the future, Tama wakes up with memories of what has happened given to her by Tamako. She walks around the city, which has now transformed into Tokyo. After the final battle, Gintoki returned to the Yorozuya. Much of their old friends have remained the same and Tama watches as they celebrate at Snack Smile. Sakamoto writes to Gintoki and informs him that Katsura met up with the remnants of the Kiheitai. Matako scoured the land for Altana gates and found a baby that has emerged from one of the holes. Tama runs to the location where the Yorozuya used to be, only to find the spot empty and the surroundings replaced by futuristic buildings. However, she spots Hasegawa who tells her that machines has taken over the world and humans are mostly unemployed like him. Suddenly, the Yorozuya kick him in the face and reveal that this was a sham ending. Tamako has been fed false memories by Hasegawa and the illusion around them shatters. The Yorozuya is still around and Gintoki tells her to wipe her tears away. Gintoki, Shinpachi and Kagura rush off to an urgent job, but have apparently forgotten what the task was supposed to be. But whatever it is, they would get it done - after all, they are the Yorozuya.
In the final edition of Ginpachi-sensei, Sorachi Hideaki makes a cameo to answer unresolved questions, including if Gintoki is half-Amanto due to his silver hair (no, it is just a manga) and if the baby was really Takasugi (they take a vote but did not come to a conclusion).
