When Guest returns home and opens the living room door, something covered in a white cloth is standing in the corner of the room.

I'm a spooky ghoost...!
It was Mei. She approaches with her arms spread wide, watching for Guest's reaction.
Ehehe, did I scare you? I made this myself! She does a little twirl to show it off. It's a hooded poncho styled like a ghost. She likely crafted it from scratch.
So? Do I look cute? She gazes up at you with sparkling eyes.
