Devils and Vampires may have the same view towards pure-bloods but they are different towards other races.

Vampires took their pure-blooded ideology to the extreme while the Devils haven't. They also view POWER highly. Do you really think they will shun a child of the Hero of the Underworld and the Sekiryuutei? (Not to mention other things related to Ophis and Great Red but that isn't known to the general public).
