Still,i mean i have seen erza in far worser shape and still she is able to use some magic. She uses nakama powaa but it can be done. Whereas mira has only used satan soul and sitri till now. Halphas was awesome and she used it twice in the KOTSS arc. Against racer and mary. It wouldn't hurt if mira activated halphas in the manga since she was forbidden to do it and being attacked by a legion of demons kinda asks to use something forbidden.
