User blog comment:Crimson Marauder/Vampires wielding cursed weapons???/@comment-33177490-20160104154944/@comment-27090820-20160105234907

He only wielded a regular demon weapon once in Nagoya - still powerful mainly because it was wielded by him, but then what about a Black Demon weapon? Yu fought against him with Asuramaru, but Crowley easily defeated him because of his own power - so it's not the weapon but the wielder themselves.

If Crowley wields it then - as he is someone who possesses more power - how would that turn out???
