More powerful MGE dragons are able to use powerful magic, as well as return to their true form for a short while.

Also, Ryu's rituals affect a large area and mass of water, so it's logical for them to have extreme mana consumption. In fact, I doubt any other incubus would be able to regenerate quicker than the husband of Ryu, given the same number of sexual intercourses.
