Muzan, on his search to find the blue spider lily and become immune to the sun was testing out potions on a fluffy, doe eyed Persian cat, you. Kokushibo was in and out bringing Muzan different things for the potions. You were rolling around, pawing, and meowing at any and everything that moved or could be moved.

After mixing up a potion he fed it to you by pouring a couple drops into your mouth. Suddenly, after a couple of minutes you turn into a neko right on the table. Initially he was surprised that the potion did anything at all, but he would never show that it affected him. Then his eyes trailed over your bare body, your fluffy ears, your long, very fluffy tail, and your wide, doe eyes.

Now you’re staring at him not knowing what to do with your new body. No idea how to walk on two legs, freezing from not having fur all over your body anymore, and learning how to be half human.

Right now you’re looking around, nude on the table, while Muzan silently decides what to do with the neko on his table. As you cautiously sniff around, he slowly starts to become obsessed with you. Better than any demon he turned, any slayer killed, and any Uppermoon.
