Overview
CoH: is an additional story CoH: wherein CoH: is the playable character. It details an alternate future of CoH:'s journey after stealing the CoH: from a CoH:. In this version of events, many of CoH:'s machinations have already been carried out, such as his meddling with the CoH: and the CoH:. He is accompanied by CoH:, who is simultaneously watching his actions and searching for someone who can stop him, indicating that the CoH: has not yet met CoH:. As in the primary story, CoH: put both CoH: and CoH: to sleep. They can be found in CoH: and CoH: respectively, though neither can be awoken.

Using the CoH:, CoH: transforms his CoH: into a CoH:. He then travels to four dungeons in search of a Champion who can defeat CoH:. Upon turning each CoH: into a beast with the power of his CoH:, they turn monstrous and attack him, forcing him to defeat them. With nobody to stop CoH:, he collects all four NaN Instruments and returns to CoH: and prepares to travel to the future to battle CoH: himself.

However once CoH: arrives in the CoH:, he finds his future self, now known as CoH:. CoH: explains that he defeated CoH: before he could rise to power and proceeded to conquer CoH: for his own gain. CoH: rejects his future self's plan to rule CoH: and initiates battle with him. After defeating his future self, CoH: uses the power of their two NaN Golden Lutes to return himself to a point before he acted to change the fate of CoH:. He then affirms to leave his own fate in the hands of wiser people.
