In the Lava Inferno—the Sixth Abyss, the demon king that was only shadow sat upon its own throne. It was watching the flame in its hand silently at the grand hall inside the depths of the Valley of Tears Fortress, just as the battle around the world of Mycroft erupted.
The flame was incandescent white and burned silently without consuming air or fuel. It appeared to be incorporeal, and yet it incessantly generated sacred energies out of thin air. Even so, the pure-black Demon King kept the flame in its palm, and each time its dark energy touches the white flame it would burst with black smoke and white vapor that filled the hall, a reaction akin to the moment boiling oil touched water.
