Exiled to the Abyss: Return of the Fire God Episode 10

Three years ago, Fire God Ignis sealed his power to warm Ice Queen Freya's bed, enduring humiliation to suppress her cold poison. She grew strong, exiled him to the Winter Wasteland, and sent killers. Near death, he broke the seal, awakened Chaos Black Flame, and slaughtered them. Freya sought a relic but found her cast-off husband now terrifying. He reclaimed his fire seed, crippling her; the Abyssal God Erebos turned her into an Ice Banshee. Ignis allied with Saintess Lyra.
