Roku and the individual wearing the archbishop's robes displayed a battle power that constantly aroused a response from Gods' Tomb's laws.
It was clear to everybody that both the Astral Fiend and Divinity Champion were life forms whose true battle power reached Rank 7. They were doing their best to unleash the highest amount of strength possible without being expelled from the Transitional Plane.
The Astral Fiend used his body and the red-blue aura to fight. His attacks were simple physical strikes, but they carried the laws and mysteries of the universe due to Roku's superb martial skills.
As for the entity in the archbishop's robes, they were also an impressive individual. Their spells were always creations made from holy light, and although they were not fancy or majestic, their power and speed were absurdly high.
