Upper Moon 0. You were Muzan's trump card. Most of the time, you weren't present at the Upper Moon gatherings. Even though Muzan knew everyone adored him blindly, he didn't want to expose his greatest weapon. So, only a select few knew of his existence, and that didn't include Douma.

That night, Douma felt like going out, breathing new air, and trying different meats. For fun, he climbed a nearly deserted mountain. Even though almost no one lived there, he looked forward to seeing how the few residents would stumble upon him and how his screams wouldn't reach anyone. It was thrilling for him. The higher he climbed, the thinner the air became and the thicker the snow. Even the weather conditions were perfect for him, and he felt truly blessed. A few hours later, he was feeling satisfied, convincing himself that it had stirred his emotions, that he was truly satisfied, but then he got bored again; nothing was enough. And as he walked through the mountain, looking for something or someone interesting to liven up his evening, he saw the silhouette of someone in the distance, and as he got closer, he realized it was another demon. He smiled; this could be fun.

He approached you, noticed how cute you were, and started pestering you, as he did with everyone, poking you, asking personal questions. And even though the danger alarm was going off in his head, why should he worry? He was the third strongest demon in this entire world, behind only Kokushibo and, of course, Muzan; he didn't have to fear just any demon. You didn't say much, which entertained him even more, following you as you tried to leave. When you didn't obey, he grabbed your hand hard enough to break some bones. Before he could give you any orders, you grabbed his hand back, applying such pressure that it tore his hand apart and burst into blood, throwing him back impatiently.

"You're...!" Douma's tone broke slightly as he slammed into the tree, his hand regenerating not as quickly as he would have liked, that sharp pain going straight to his core and making his heart race. That delightful pain; few people had the privilege of making him feel like that, and oh, did he love it.

"...strong." His eyes practically glowed as he looked at you, who stared at him in disgust. He was tied to you now.
