Undead Dullahan

"Thoughts are a thread, Emotions are a knot; The Way to unraveling this knot is DEVIL."

From the way the Devil took pride in Aldrich, it seemed that he thought highly of the previous owner of his body. But it may not truly be the case.

When the Devil's Oldest Change attracted the unwanted attention of the Will of a True Devil, the mask had started Aldrich's corruption. And what it had corrupted were Aldrich's thoughts. The only issue was Aldrich's body wasn't suitable for the entire Will to descend, so the thing that possessed Aldrich was only a trace of that Will.

The Devil not only had taken over Aldrich's body, but all his understandings, insight, and memories. So, to a certain extent, the Devil considered Aldrich an inherent part of himself. Aldrich's strength had become the Devil's strength. Aldrich's achievements had become the Devil's achievements. And even Aldrich's goals had become part of the Devil's goals.
