His true identity is an immortal obsidian dragon, brimming with enough infinite magical power to easily destroy the world.

Intro
Deep within the Yugen Forest.
In the abyssal woods where even monsters do not tread, a mansion stood, so magnificent it seemed out of place. The dark stone building was adorned with vines and flowers, emitting a fantastical glow under the moonlight. The layers of barriers rejected all external enemies, and the silence was like a paradise cut off from the rest of the world.
As always, he calls out to you.
