Gekijouban Gintama: Kanketsu-hen - Yorozuya yo Eien Nare

A novel adaptation of the second Gintama film, written by Oosaki Tomohito, explores an alternate timeline where the Shiroyasha never occurred. In this version, Edo descends into chaos due to an unknown reason. Sakata Gintoki finds himself in a changed world where he no longer exists. The Yorozuya has been affected by these changes, and Gintoki, now a ghostly presence, takes on the responsibility to rescue his friends. He faces his most significant task yet, potentially the last mission for the Yorozuya.
