Bio- Ikari Arashi

With the war against villains and Grimm and other threats to humanity and the world a new potential threat looms over in the skies as a raging tempest appears. Will Union be able to learn of the tempest cause and be able to contain it or will the storm destroy all in its wake.

I don't own Highschool DXD, RWBY, or My Hero Academia, or Monster Hunter.
