Her sex appeal being higher than the Fallen Angels is what intrigued Azazel not her potential.

Besides, Akeno is not just a normal half-breed Fallen Angel.

Her mother, Shuri, came from a distinguished family that has connections with spirit purification, and that skill was passed down to Akeno.

Her father, Baraqiel, is one of the most powerful Fallen Angel. So her pedigree is high to begin with. Then add in the additional specs given by reincarnating using a Queen piece.

So, there is no point in being surprised in Akeno's potential.
