The first season of "Yasuke" sets up a lot of storylines to be explored in new episodes. Yasuke successfully protects Saki and saves her from the Daimyo, who wants her powers. Although it appears that everything's under control, Saki is warned by the Daimyo that her powers will continue to grow, and soon she'll be unable to control them, with the only goal being to find more power and wreak destruction. Yasuke leaves Saki safe at her village, but this ominous warning could be prophesying another meeting between the two characters when they're older, when Saki's power is out of control and Yasuke must stop her.
Another storyline that could be expanded on is featured in the finale's post-credits scene. Yasuke carries around the sword of an old friend named Natsumaru, who he was forced to kill on the battlefield. He finds Natsumaru's brother to finally give his sister's sword to him, but he doesn't reveal his direct involvement in her death. It's possible that the brother may become a more important character going forward, finding out the truth and going after Yasuke, or the scene could simply be some much needed closure for Yasuke and Natsumaru.
The show takes on Yasuke's story after the real historical figure went into exile, when very little is known about what happened to him. Because of this, the writers can essentially go anywhere with the character, and with the expansive world that's been established in the first season, the possibilities are endless for "Yasuke" Season 2.
