Gyokko
Sadistic Artist
As a child, Gyokko was shunned by his fellow fishing villagers for having an obsession with collecting fish carcasses.
For some reason, Gyokko was intrigued by art and the sea as they became his hobbies.
Whenever his parents died at sea and returned as salt-water ruined corpses, he was fixated on their morbid beauty.
One day, he was insulted by a village child for his behavior. Enraged, Gyokko killed the child and somehow stuffed their body inside a vase.
Outraged, the village stabbed Gyokko multiple times then leaving him for dead.
It was then on the brink of death, that his unknowing prayers were answered. Dagon, the demon lord of the Darkened Depths offered him power for nothing.
Though the reasoning of the mysterious and inscrutable demon lord was unknown, Gyokko accepted becoming a powerful demon.
With the gift of never ending life, Gyokko dedicated himself to his art for the pleasure of his new master.
