Legend says, that there is a great demon, who is the human kind’s public enemy. He is the galaxy federations’ nightmare as he wanted to conquer the whole universe. On the first day, he completely took out the human fleet, plunging them into disorder. On the second day, he declared that he will wipe out the whole federation. On the third day, he declared——that the hero who shot him in their previous battle must marry him, or else, he will destroy everything.

The galaxy federation president and the council members had a long meeting after that. They decided to dispatch a soldier, Wu Xing Yun, and marries him off to the arrogant demon. Wu Xing Yun was once a hero who fought for the nebula, and henceforth, he was tasked—— for the sake human race and the universe’s peace, to eliminate mistresses, settle his matters with the mother-in-law, and fix the man’s crooked ways.

Wu Xing Yun was very perplexed when he asked his commanding officer: “Sir, why did it have to be this way?”

Commanding Officer: “Soldier, bear in mind, that this mission of yours, is for the sake of the universe and mankind’s happiness. You must hold on to your husband, and fight other mistresses! Do you have the confidence to accomplish this task?”

Wu Xing Yun, stood straight, saluted, and instinctively replied: “Sir, yes sir! I will accomplish this task!”

Estaria, the Goddess of creation and eradication. The daughter of the God of destruction and the Goddess of life. Her father has been dead ever since she was born, and her mother disappeared without leaving a trace. In desperate times, as she grew old, she decided to bring her father back to life. But she had no idea where her father was. So, with nothing else to use, she thought of just recreating him through reincarnation. But the reincarnation process needed a woman whose body was strong enough to host the reincarnated vessel. With no options left, she crafted smaller deities using her own fresh and blood. Many of them failed. But one whom she named Nanako succeeded bearing a child she then named Hajime. Yet Hajime wasn't exactly what she expected. Because he possessed dual souls from two different people who died simultaneously in another world. But she was unaware of them due to one of the souls having fragments of his memories from when he was still alive in his past life. The other soul had completely forgotten everything, but bit by bit as the individual called Hajime journeys this new world, the memories of the other soul would start to retain giving him split personalities.
