The rattling sound was clear.
And the flames were visible from the sky on an empty island not far from the coast of the Seriz district. Even if the flames looked like they were burning all the trees on the empty island. Even able to eliminate the island at once.
The flames were getting bigger and bigger out of control. Petra stood fifteen centimeters above the ground as the center and continued to stare intently at the group of faintly shaped Demon Kings. Like a mass of shapeless black smoke or the shape of a half-perfect strange creature.
And it's not at all a pretty sight to look at from Petra's point of view though. A group of faint, unclothed figures writhing in pain accompanied by a pitiful howl. Inevitably Petra's conscience trembled because of it.
