Theme: Silly fluff

Note: Kokuzan are dating in secret! (Only naki knows btw) – Idea by le amazing @GiyuuTomioka9374

“Okay, remember. Keep. It. A. Secret,” Muzan ordered, his hands on Kokushibo’s shoulders as he looked into his boyfriend’s eyes—or at least the two in the middle.

“Yes, I know, we’ve been through this 1000+ times, Master,” Kokushibo sighed. 

“Yes but I need to make sure you-” Muzan started. But then the demons started arriving and he quickly stationed himself above the platform Kokushibo stood on. He gave the demon a warning glare and then cleared his throat. “All of you are lacking in your missions,” he said, raising an accusing eyebrow. 

The demons all lowered themself in a bow, silent. Kokushibo did the same and waited for Muzan to continue. “I must assign all of you to more missions because clearly you assume that you’ll have enough time to finish all of them now.” 

Nobody spoke, all waiting for him to elaborate. 

“Very well,” Muzan said. “Kaigaku, as you are new to our ranks you must learn most. I will have you take care of two villages per day.”

Kaigaku nodded, his throat tight with fear. Kokushibo had been terrifying to encounter as a human but as a demon, when Muzan had even more control over him.. 

“Nakime, you must continue searching for the demon slayers faster,” the demon lord ordered, turning to the biwa woman. 

“Yes, Master,” she said, her hair splayed out as she mapped out the locations of those in the corps.

“Douma, stop paying such attention to your cult members and eat them for strength in the times to come. Akaza, you must locate the Hashira as Nakime is doing with the demon slayers. Find them and kill them now.” Muzan paused, wondering what to make Kokushibo do.

“And you,” he said, turning to his secret boyfriend. “You have been doing well, it doesn’t matter. Just continue as you’re doing.”

Kokushibo nodded, not having expected this though. Muzan clapped his hands and Nakime plucked the strings of her instrument, taking the demons to their locations one by one. And then it was just Kokushibo and Kaigaku. Muzan, not having noticed Kaigaku, turned to Kokushibo and started to speak. “Alright, let’s go now, Kok-” he paused, noticing the last demon. “Nakime!! Take him to the first village! Now!” 

Nakime did as she was told, but not before Kaigaku looked suspiciously at his superiors. 

Kokushibo sighed, although a bit amused. “Right.” 

Both demons went to the office of Muzan’s and sat down on the couch, talking quietly. Muzan kissed Kokushibo and said, “I don’t think any of them noticed.”

“Kaigaku might have,” the multi eyed demon said. 

“Most likely not.” 

“Perhaps.” 

They dropped the subject there and continued on talking.

~~~

As weeks past, Muzan and Kokushibo continued hiding their relationship. Nobody seemed to notice it, yet, except Kaigaku who’s eye was starting to pick up things as he focused more. He didn’t say anything, though, deciding he didn’t want to get in trouble. 

Muzan kept calling the uppermoons for meetings checking up on their missions and such to make sure. He seemed to be planning some big attack on the demon slayer or something because he was suddenly focused on their training. But this also gave him away more as he favored Kokushibo over the rest of them and constantly tried complimenting him in a way that he appeared to find subtle. 

But subtle was probably a description of what he was not.

Muzan would say things such as, “All of you are so weak. Take over Kokushibo’s examples, he’s a lot stronger than most of you and he barely trains!” or “Kokushibo exceeds every single one of you. I’m beginning to think I should kick all but him out of the upper ranks.” And so on. 

Most of them were used to this but Kaigaku, who was used to being the stronger one, noticed it was more favortism than truth. The demons were all getting a lot stronger but Muzan either didn’t notice or just cared more for Kokushibo. And most likely it was the latter.

Kaigaku decided he couldn’t take it anymore. 

On their next meeting, Muzan gave them their daily rounds of “You are growing so weak” and “Kokushibo is better than you’s” before moving on to a plan of defeating the Hashira and Ubuyashiki in a week’s time. Kaigaku studied his lord and the Uppermoon who’d turned him into a demon closely. He found their eyes constantly meeting and Muzan’s gaze lingering on Kokushibo throughout the whole discussion that he didn’t know how the other demons hadn’t found out yet.

At the end of the meeting, as Muzan started to wave them off, Kaigaku turned to Nakime to tell her to stop. Nakime did but Muzan didn’t notice, taking Kokushibo’s hand into his own. Kaigaku smirked as Muzan tilted himself up to kiss the Uppermoon. 

Kaigaku cleared his throat and Muzan’s eyes widened, turning to his demons who were staring at him, shocked. “So.. are you two dating?” Kaigaku asked, his arms crossed.

“Wait, no-! That’s not it, I was, uh,” Muzan stuttered, scrambling for a response.

Douma said, a confused smile playing on his face, “Were you going to kiss him?”

“No!!” Kokushibo and Muzan said at the same time, both of them looking flushed. 

“But you two keep staring at each other so much during the meetings,” Kaigaku pointed out. “I’m sure you are dating.”

Nakime stifled a smile and Muzan, wondering how the fuck he hadn’t realized they were still there, shook his head rather violently. “I don’t.. I don’t do dating. It’s.. it’s not something demons should interact with.”

Kokushibo raised an eyebrow, deciding he didn’t care if people knew. “We are dating,” he admitted. 

The other uppermoons gasped as if they hadn’t known—Nakime pretending and Kaigaku out of amusement. Muzan grumbled and turned to Nakime making her teleport him away. Kokushibo sighed. “Right, I’ll be on my way.” 

Kaigaku smirked. “Have fun with your boyfriend!”
