Demon King Gremory II
A game of cat and mouse was currently happening in the skies between two snowy mountain peaks in the Northern Continent of the Beast World. Who the cat or the mouse was could not be clearly identified at this time, as the roles seemed to change over time. More than 30 minutes had passed since this chase began.
It was two ferocious-looking beings flying through the skies, a silvery light appearing every now and then as one teleported a few miles away, only for the one chasing to catch up a few seconds later.
The reason this chase was occurring was because a powerful sigil that was spread for more than 30 meters had caused a tremendous amount of damage for a winged demon and his Primal Spirits, and that sigil had disappeared after thirty seconds. This scene repeated itself multiple times in the past half hour. The disappearance of the sigil drastically reduced the power the white-furred incarnation was releasing, causing the current scene.
