Magic Power is actually just a general term, while Demonic Power, Light Power, etc. are the specific terms used to refer to the power of a certain race/species.

Every supernatural being has "Magic Energy" of some sort. The type just changes depending on the race/species.

Demonic Power is basically a Devil's Magic Power.

As for MacGregor Mathers (and any other Reincarnated Devil), I can think of two ways to answer your question:


 * When he was turned into a Devil, his Magic Power became Demonic Power.


 * When he was turned into a Devil, his original Magic Power and the Demonic Power from the Evil Pieces (Bishop) combined into one. So the Demonic Power enhanced his Magic Power.
