After the end of Eternal Everything, he entered the Soul Society to avoid the disappearance of the Nightmare Gintoki.
The writing is poor. The inspiration came from a large drawing by an artist of Gintoki wearing Haori, the captain of the 13th division, and there was an introduction to the soul-cutting sword next to it. I searched and found no article, so I started writing. Bleach has only watched the anime, so it will be very OOC.
