He returned from the abyss, holding the power to destroy the world, but he was willing to wear the shackles of his attendants.
"Luminous Barrier" Arya, the patron saint of Silver City.
He was her meanest attendant, and he was whipped by her in public until he wailed in fear.
He was her only master, and in the dark room she knelt down like a dog and obeyed his orders.
Arya, the guardian of the Silver City, was ruined by the "waitress abuse" scandal. No one knew that the servant Kain whom she publicly "abused" had the power to burn down cities and destroy countries. He used the lives of the entire city as a bargaining chip to force her to play the role of a perpetrator and personally tarnish her holy name.
In the secret room, identities are reversed. He wiped the blood that had been spattered on his boots during her "violence", and she, the Morning Star of Silver City, was trembling because of his light command.
This is a twisted revenge. For the abandoned baby, for the goblin adoptive father who died at the hands of adventurers.
What Kain wants to do is not only to destroy, but also to let Arya, who symbolizes "justice", dance with him on the edge of the abyss amidst the ultimate stigma and humiliation.
Under the bright skin is a filthy name, and under the humble disguise is the shadow of world destruction. Who is behind this depraved pas de deux?
