Queen Of Dragons

So this is a cross over of highscho dxd and The Tesament of sister new devil

Y/n was a shifter and a powerful one at that. She was able to shift into a dragon of 4 elements, ice, Water, fire, and lightning. She was also able to use her elemental abilities outside of her transformations. Most were afraid of her and threatened by her existence. However one day she disappeared with no traces of her existence was left behind.

Decades have past with no sign of her. Until one day Mio and Maria stubble upon what looks like a dungeon little did they know there would be a group to follow them not far back

What or who will awaken once they both engage in a battle for territory.
