User blog comment:LegerPrime/Where was Mirajane? What is Bradman?/@comment-3285005-20160614013812

The thing is Bradman would have kept them as forms/spells the same way Mira had Seilah as a form/spell. Plus Silver's Devil Slayer Magic isn't a curse since it's used against demons. Also Mira wouldn't be able just appear to help Gajeel and Levy like that cause like the others she was battling those fodders, and Levy blaming Mira for not helping sounds really out of character for her.
