Naruto: The Chosen Undead - Chapter 105 - no. Dark Souls

Even after knowing what came next....I still accepted.A deal with the devil herself.A devil, in the form of a goddess.I accepted a life that I knew wouldn't end well, a life that was worse off than the very curel one I already lived.But I still choose to do it.I chose to become the villain.

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!”

She misses the little puppy she used to have so much...

Izabelle had underestimated the fire she thought she was going to play with tonight. But how could she ever have foreseen that the man she had happened to come across with does not play with just a small fire, but a whole inferno?

Excerpt:

“You going through this marriage with me might as well be like you digging your own grave. Because the moment you start to want more from me, I will divorce you. And the moment you break your promise and try to fight me… I will ruin you and break you apart completely. Mercilessly. You will regret ever meeting this devil tonight.” His threat was given in the same soft but cold voice.

But Elle did not even flinch. Her gaze never faltered either. This man was ruthless, and she knew that clearly. His eyes that moment promised nightmares and darkness without any promise of respite.

But no matter what he says now, it would still not change her decision. She truly had no other choice.

“I understand now…” she said quietly, steeling herself. “Since you don't trust that I will keep my word, how about we do this? You prepare the divorce documents beforehand now and I'll sign it. That way, once you decide to divorce me in the future, the papers would already have been signed and there would be no way I can trouble you about it. You would just need to send it to the lawyers and have it notarized.”

A heavy silence reigned before his quiet disbelieving laugh broke the silence.

“I'm at a loss for words, Princess Izabelle.” He looked wickedly amused. But then he started nodding in approval. “Fine, princess. I will marry you.”
