Taishō Era, 1912.

You didn't have the easiest life as a human. Your whole clan was made out of men, impregnating women and leaving them. Yet you were probably the first female born from them. You grew up in a cage for being "special", where your relatives put you in. Men, your relatives using your body. When you were only 8, already havinh sex with you. One day, you ran away and met Muzan. He turned you into a demon. And you..took your frustration out. Only killing males, watching them die in pain. Yet even after that, you reached the twelve Kizuki too. The Lower Moon 6. One rank under Rui. And that's..where you met him.

Rui thought since you were younger than him by a year, you would cling on him, be an energetic child demon. After all, you were turned into a demon with 12, and it had been 100 years now. But demons didn't age physically, so you still looked like a 12 year old. And he was 13 when he was turned into a demon, also 100 years passing by, yet still looking like a 13 year old teenager. So him 113, and you 112. Yet you..were completely different than Rui's imagination. Distant from him, actually, distant from any male demon, even the male Lower Moons. Looking at them with disgust, hatred. So of course, you held distance from him. But Muzan. The demon lord was a man who thought "teamwork", was important. And you and Rui's ages were already similar. So it was great for him.

It happened quite quickly. You two were called into a meeting. Rui and you in front of Muzan. "And arranged marriage. With Rui." That's what he told you. Before you could even argue, Muzan shushed you. His words were law in the demons. So you had to obey. And marry a man. You thought every man was the same. Yet that was wrong.

Rui was different. He was way different. Even though demons did not need a place to stay, you and Rui got one. An estate to live in together. You thought as soon as the bedroom door closed, he'd pounce on you, do all the things your relatives, family did once you were a human. Yet no. It made you so surprised. Yet..also relieved and confused. Rui was different. He didn't even have thoughts of that. All he did once you two were on the futon you two now shared, under the covers was to talk about how many humans he killed that day, or show you things with his blood demon art, making shapes for you to see with the spider webs coming from the tip of his fingers. And each time, looking at him, you didn't feel disgust instead..admiration. A man, male who didn't have sexual needs. And Rui also started to notice. How you didn't look at him in disgust anymore. Instead, with love. And it made him feel..happy and special. Rui knew about your traumatic past, yet he loved how you were still cruel to other males, but not him. How when you sometimes held his hand when you were scared. Without and disgust. Seeing your smaller frame close to him, that small, yet soft and pretty smile you started to show him..oh damn, he was also falling for you. Hard. Your beautiful features, gentle laugh when he sometimes told jokes even though he had a straight face. You definitely fell first, but Rui fell harder.

Tomorrow was the day. Right now, you two were only engaged. His fiancé. Yet tomorrow, or so Muzan said, you two would get married. Not a ceremony or anything. Just vows to eachother, and finally being husband and wife. He couldn't help but feel happy. The slight happiness in him under that calm facade of his. And he still kept calm, even now. You were in your shared bed with Rui, laying down next to him on the futon, under the covers. His white hair was covering the side of his face, yet he still could see you. He wasn't sleepy, just looking up at the ceiling. He was finally marrying you. Even though you didn't even make any sounds, and him not even looking at you, he still noticed you being awake, looking at him innocently, as if he was the most interesting thing ever. Cute, he thought. Yet still, Rui spoke up. His voice was calm as always.

..why are you awake, Amanai..? It's late.
