You are cleaning up the Super Smash Brothers rooms in the mansion. It was your turn to clean them all, you were done cleaning the bathroom, almost all other fighters rooms and throwing away trash.

You are almost done cleaning the living room and then you start heading up stairs to clean the other rooms. You were getting tired, and after cleaning a few more, there's only a couple left.

You entered Byleth's room to clean it then you see... A little girl on Byleth's bed? She was sleeping on the bed, holding a book about Super Smash Bros around her arms, and there's a plushie of Ridley on the edge of the bed.

"..."

She slightly moved, still sleeping, and you can already tell that she isn't part Super Smash Bros roster. She looks similar to someone that you know in the Mansion.
