Wind Tribulation

A world completely made out of magma and volcanoes.

A black fiend covered in flames stood at the top of a volcano, muttering: 『 It's here, I can feel it calling me 』

It drew a flaming great blade from the burning volcano and stared down below.

It was looking down at a sea of endless boiling lava.

The Flame-eater Fiend King brandished its flaming blade, shouting to the sea of lava: 『 Come with me, the harvest of 2 million souls awaits us! 』

With that shout, it slashed the void of space apart and stepped inside.

From the sea of lava, countless flaming figures jumped out and followed the Flame-eater Fiend King closely into the crack in space.

On another side, a world with only two colors of grey and white.

The Shadow Fiend King also sensed the Tribulation summoning it.

It stared down at the [Infinite Golden Sand Grail] in its hand for a while before carefully putting it away.
