"Roaaaar" an Otherworldly beastly sound left Seth's throat along with the torrent of flames, shooting in a straight line and smashing into the window in front of him.
For about a second, the flames were held back by the seemingly fragile window, but in no time, the sharp screeching sound of glass shattering was heard and the window was blasted apart.
The screeching sound came from the barrier which had been placed on the building and by proxy the window being destroyed, and with it now gone, Seth should have seized his attack and bolted out, but he didn't.
The window was destroyed and his whole body was now being hit by sunlight, but Seth didn't let up on his flames, instead, he bent his knees a little and took up a firmer stance, increasing the intensity of his flames.
