Uppermoon cat AU

So I was scrolling through Tumblr, as one does, when I noticed drawings and comics by @6chimeraqueen9. They included some absolutely amazing drawings of Muzan... as a cat.

I felt inspired. So shout out to @6chimeraqueen9 for the idea.

I wanted to make an AU where the uppermoons got reincarnated after their defeat as house cats. The story will be from Muzan's point of view from being taken home by a (lonely and depressed) woman. It will just be a bunch of fluffy shenanigans as Muzan tries to find a way to make himself normal again.

Uppermoon Cat AU Part 7

I don't own demon slayer. All rights to Koyoharu Gotouge. I only own Lu.

Muzan was tired. Lu was tired. And they were both HOOOOT. The sweltering summer heat was killing them both. Unfortunately the AC unit broke only a few weeks into summer. The repairmen wouldn't be there for a few more days, leaving them both at the mercy of the humid summer air.

Useless. Muzan thought, rolling over on his stomach. The two laid on top of the sheets of the bed, sweating out the heat. Muzan once again cursed the sun, it seemed to hate him in every life.

Lu groaned, flopping onto her back with her arms spread out on either side. "This is agony." She murmured. Muzan grumbled an agreement, but it only came out as a curt meow.

With another groan, Lu sat up, pulling at her sweaty shirt. "This isn't doing me any favors." She murmured again, yanking the shirt off.

Muzan blinked lazily. Then his head snapped up. Lu was in a bra... this was... unprecedented. But it was only natural in this heat. Still though, it would have felt indecent. That is, if Muzan felt any shame at all. Seeing as Lu was his patron, Muzan felt no need to hide his stare. His gaze trailed along her body, the breasts hidden by the layer of fabric that made up her bra, the rise and fall of her stomach and chest as she breathed, the stretch marks along her stomach, the line where her shorts and skin met, to the outline of fabric that hid- Muzan's thoughts were interrupted by a small scoff.

"Is my cat judging me now?" Lu half-joked, laying back down on the bed.

Judging? Not at all.

Lusting, however... perhaps.

Once again Muzan cursed his feline form.

Uppermoon cat AU part 3

I don't own 'demon slayer', but I do own Lu. Mentions of suicide and depression.

Muzan learned two things after that night.

First, this human was a mess. Lu was a mess to the point it would be annoying if she did anything other than work and lay in her bed. Some days she didn't even work.

Second, Lu took better care of him than she did herself. That annoyed him a bit. Even if she was having one of her bad days (read; curling around herself in bed and sobbing), she would still get up when her alarm went off to feed him. Or when he paced by the doors to go out.

It was rather confusing for Muzan. This human was more willing to look after a literal cat (even if that cat was him), more than she was willing to care for herself.

At first, he didn't care. He had no reason to since she continued to feed him that (reluctantly delicious) cat food and let him roam about. His only priority was returning to his previous form.

However, after that night, Muzan added another item on his priority list. Keep Lu alive. He would rather have her be his patron then another random human who might be more annoying so he couldn't let anything happen to her... yet.

So he began acting... civil. On days when she wouldn't (read; couldn't) get out of bed, he would make himself at home on her covers. He wasn't sure how to comfort people, but her sobbing became less annoying when he laid with her. On days she drowned herself in work, muttering to herself. He would keep an eye on her, just to ensure she didn't do anything rash. He even bothered scolding (read; meowing insistently) when she didn't eat that day.

It wasn't until two weeks later that something shifted. It was another bad day. A day where Muzan begrudgingly resigned himself to staying with the human who simply laid in bed. Lu was just staring at the ceiling. A blank look behind her eyes that reminded Muzan of a corpse. It was almost nostalgic for him really. Usually Lu wouldn't speak during these times, which was fine for Muzan since he hated small talk. It seemed today wouldn't be a silent day though.

"... I'm sick, y'know." Lu murmured softly. So quiet Muzan wasn't sure he actually heard her at all. "Not like a cold or something, but something in my head is just... wrong." She didn't seem to be talking to him. More like muttering to herself. Lu closed her eyes again, likely trying to sleep. She did a lot of that.

Sick. Being unable to leave a bed. Some wrong.

That hit a bit to close to home for him.

I stumbled onto your Uppermoon cat AU and it's become one of my favorite AUs to follow. I don't have the same degree of Lu's struggles, but it's hard not to relate and I know things wouldn't be as stable as they are if I didn't have my own cats to live for.

It's a job to see Muzan as a cat and I love how you captured his personality. I'm also dying that Douma is the first Uppermoon that he reunited with. Looking forward to more of your work.

Omg! Thank you so much, this means a lot to me. I tried to make Lu relatable on some level, but she was mostly based on my own social anxiety from 2021. Don’t worry I’ll continue to post for Uppermoon Cat AU!
