I wonder what would have happened if Shiroyasha had never existed? One day the world went crazy, and now Edo is plunged into real chaos. Sakata Gintoki now lives in an alternate reality, a future in which he could not find a place. But what happened to Yorozuy? And with the rest? But most importantly, who is behind all this? It looks like Gintoki again has to become a demon in the flesh to protect his friends. He alone will have to manage with the greatest mission in the history of Yorozui and try not to become the last.
