The God of Darkness, along with his brother, the God of Light, used to love and value Humanity until Salem manipulated them and turned Humanity against the Gods. He was disappointed that the Humans used his gift of magic against him and his brother. The God of Darkness ultimately decided to destroy Humanity for betraying him.
The God of Darkness is the younger brother of the God of Light. He appears to be hostile towards him and his ideals about life, but does show loyalty and caring towards his older sibling as when his brother told him the truth about Salem, he put his pride aside and apologized for his actions by destroying the resurrected Ozma, and also came to his brother's side when Salem's rebellion invaded the Domain of Light.
At first, the God of Darkness was impressed but very pleased, that she chose him instead of his brother unlike the rest of humanity, and granted her wish to revive her deceased lover. After his brother told him the truth about Salem, he was angered that she asked his brother first instead of him. The God of Darkness along with his brother cursed Salem for her selfish and demanding nature in her attempts to revive Ozma.
