In Zoroastrianism, the mother of evil gods is the source of all evil and darkness!

Legend? Created six demons of “Malicious”, “Chaos”, “Aging”, “Defection”, “Weakness”, and “Destruction”!

Saigo, who obtained the spirit of the “Mother of Evil Gods” in Hakoten, became the “Supreme Supreme” in the overlord;

Look at the ‘ruler of death’, ‘Void Witch’, ‘Tivat’s Demon God’, ‘The Great Demon of Gensokyo’, ‘Dxd’s Demon’, ‘Creator of Demon God Pillar’ and others;

Xixiang is convinced that he has lived up to the name of the “Evil God”;

That being the case, he would shout out the phrase – God is dead!

- Description from novelbuddy

As his contract-marriage wife, she just wanted to fulfill the mission given by his mother—having a baby. They didn't love each other, so he always used contraception before they got laid. She had been obedient to him, only to find that he had gone too far! He actually didn't care about their child at all! She couldn't stand it anymore, so she handed him the divorce papers and left, noting: “The world is so huge that I can surely find a better man.”Looking down at her, he retorted, “Come on, your purse strings will tighten up first before you find anyone.”
