Warriors Orochi 3: Ultimate - World's End (Chaos)

This stage is the harder version of The Demise of Orochi X, having more enemies, a constantly reviving Kiyomori, more sacred orbs to destroy, and even the Hydra to attack you. You only get this stage by having unlocked all characters, so your allies here are a bunch of random characters that were missable. They went with some boring choices though in my opinion, particularly with leaving out Lu Bu. But anyways. The True Ending has everyone survive and defeat Orochi, but the world can no longer hold itself together now that his power is gone. So the mystics use their power to send the humans back to their original timelines as if WO never happened.
