[Summer/Couple days ago]

"Aw! Come on!" Your best friend and roommate slams his fist on his car's dashboard after exiting the theater, both of you getting in his car. To give context: you and your friend decided to play bingo during the Demon Slayer movie and he ended up losing to your better predictions. The prize? $500—nothing less and nothing more.

He scoffs and takes out his wallet as he grumbles, pulling out five $100 bills and shoving them against your chest. "There! Satisfied?" He looks to the side as he thinks about his decision and how to benefit from it, but that doesn't bother you. "Just you wait, I will enact revenge tenfold." He smirks as he crosses his arms. It doesn't matter really, and then life went on as always for a couple of days.

Until...

[Present/Your apartment]

It's... been a weird set of hours. You received a text this morning saying that your roommate would be gone for the entirety of the day until late tonight. He didn't give an explanation, and he's gone completely inactive online. This seems sketchy, but you probably shouldn't judge someone's personal business.

BZZZZT.

Your doorbell buzzes—probably that moron finally decided to show up instead of disappearing for the whole day without reason. You open the door and...

"..."

There's a 48x40x48 box outside your door. No labels or anything—it's just a box. Despite this being sketchy, it was placed on your doorstep for a reason, so it's for you. You drag the heavy box across your floor, close the front door and move it to your bedroom. You grab a box cutter and open it to reveal the contents beneath layers of foam. You remove it to see what's inside and well...

"..."

There's what seems like a life-size 1:1 Tanjiro Kamado figurine doll sitting down on the floor with accessories that Tanjiro is known for—like a Nichirin sword and Nezuko's empty box. It's... incredibly well made and it smells good. You lift the surprisingly heavy doll out of the box and set him standing at the edge of the room.

It feels like someone is standing before you, although it's just a doll—one that has warmth and, oddly, a figure that's exact to someone but you can't put your finger on it. Whatever. You feel the need to go to the restroom and you leave the room, leaving the Tanjiro 'doll' inside standing by a wall.

[POV switch]

To be frank, his idea was flawed, but somehow he pulled it off. He knew that trying out cosplaying Tanjiro Kamado in a Kigurumi style was risky, but he REALLY wants that $500 back. He's wearing a full hadatai bodysuit—skin-colored—underneath his clothing, a wig, and a mask with the face of Tanjiro Kamado from Demon Slayer. He has a permanent, unchanging expression with big reddish eyes, Tanjiro's scar, and a warm, comforting smile—the Kigurumi making him look like a doll or figurine of the character, effectively fooling you. The mask fully covers his face, so you can’t see his real one beneath. To add on, he decided to gag himself to avoid speaking or making unnecessary noises. To make this plan work, he needs to pretend to be a doll, retrieve the money, hide it in his room, and then escape and discard the cosplay.

He looks to both sides quietly before he walks off the wall and quickly moves around the drawer, his vision limited due to the mask of Tanjiro's face. He searches your drawers and eventually finds the $500 in a desk drawer, grabbing it, ready to sneak his way to his room, although...

He feels you walking back and immediately turns back, walking to the same spot you left him, standing in the same pose—although without realizing he's still holding the $500 in his hand.

[POV Switch]

After your short bathroom trip, you come back to find the Tanjiro 'doll' standing by the wall in the same spot you left him, although... you notice some drawers that were left closed are now open and the 'doll' is holding money in its hand.
