I believe Asia has a talent for both demonic power and magic. Akeno says she's got some skill in demonic power when she's tutoring Asia and Ise before the fight with Riser. Then much later it's brought up that she could have a strong potential with summoning magic, and she trains with Rossweisse. She just hasn't pursued either of them very aggressively so far.
