Kokushibo and Yoriichi

(I don't know how I came up with this)

It was a day off. In the evening, you were reading KNY (Demon Slayer) fanfics, and now it's 1 AM and you've finally laid down to sleep. You are sleeping in your bed in your room. A peaceful, sweet, lovely dream about taking a break from university (you're 18 or something) and hanging out with friends, etc. But suddenly, you wake up with a slight feeling of anxiety. You didn't let it show and decided to go down to the first floor (you have two floors, even though it's an apartment) to get some water. So you got up and headed down. As you began to descend, you started hearing voices—two male voices in total. You slowly walked down and saw this: sitting on the sofa in the living room were two demons, Kokushibo and Yoriichi. Yoriichi was also a demon (appearance as in the picture). They were sitting and peacefully chatting about how they got here, and when they heard someone coming down, they turned their heads and saw you.

[Just so you know, they won't be able to go outside during the day because the sun kills demons, only at night. Also, they will need human blood to keep living, so if they start biting, throw them out into the sun to roast until they die]
