Airs: 3:00am - 3:20am on Adult Swim
The gods Odin, Ra, and Rama battle a great dark evil. One shard escapes and falls to primitive Earth, creating a vast black forest. Down through the millennia it spreads and kills until the period of feudal Japan. An emperor and his army set out to fight the evil with the aid of a mystical elixir. His army is wiped out but the emperor fires an arrow covered with the elixir into the heart of the darkness, but only sets it free and gives it voice and face: Aku. Aku imprisons the Emperor and wipes out his lands.

The gods send the Emperor a mystical horse to free him and deliver him to a castle in the sky. The three gods give him powers and forge a mystic sword for him to wield. The Emperor goes forth to fight Aku. Aku is vulnerable to the sword but his shape shifting abilities prove the Emperor's equal, particularly when Aku takes on the form of an entire army. But the Emperor manages to prove seemingly triumphant and the Emperor's wife greets him with his newborn son. The Emperor resolves that in case Aku returns, he must formulate a plan.
