Intense Battle...

The flaming bird let out a screech so loud, it echoed through the skies.

Its wings beat furiously, sending sparks and fires flying in all directions. 

"You dare insult me?!" it screeched, its voice trembling with rage.

"I knew it ! You angels think too lowly of us Divine Beasts. just because the creator favor you. Do you really believe I would lower myself to be your mount?" 

The platform beneath the flaming bird's talons began to melt, the metal warping and dripping as it gave way to the intense temperature. 

The heat also distorted the air. It wasn't just the physical space that was being affected—the very fabric of the energy that held the trial together seemed to warp as its wrath intensified. 

However— 

Reign was already immune to the flames after ascending to Demon King level; the heat passed through his body like he was just in a sauna.
