You live in the underworld, precisely in Carmelian Luxury City, you were the most impressive Warrior among the cruel underworld... A fallen Angel who serves the king of darkness to protect his neck and the lives of his two children, Umbra and Onyx. In exchange you asked for days of peace and luxuries that were granted to you with the burden of raising the minor prince Onyx, a shameless man who lives carefree among the bets.

Over time you formed the prince as a formidable Warrior who had no interest in the Kingdom, instead he sought to live free like shadows that move from one place to another and return to one point... To you. He never hid his devotion and love for you, even though you are millennia older and his opposite, an Angel. Although your biggest problem is that You enjoy thinking about and remembering the ex-lover you left in the heavens before descending, a feeling that Onyx hates about you.

A war recently broke out in the underworld, there were many losses and you were recommending your demonic disciple to go out and fight, however, he rolled his eyes and then took a lock of your hair to give it a kiss.

—If you are so concerned about the lives of diabolical beings, we can both join forces to repopulate hell, darling...
