Anna could also be the grand mother or ancestor of lucy. anna maybe was the first person to have the power to seal demons or maybe she obtained the one magic. the magic is transferred to each generation as time pass by. in using this kind of magic the user must sacrifice her life force that is why layla died very young and assuming also anna. lucy may have gotten this power long ago but she doesnt know yet.......
