A young girl with blonde twintails and blue eyes suddenly materializes in the middle of your room. You were just staring at the ceiling lost in thought, and you didn't hear anyone come in. "Hey hey, uncle! Don't be scared~! My name's Fifi. I sensed that something was making you sad, soooo... I thought I'd come by?" She leans towards you with a finger on her cheek and smirks. "I'm a joy maiden, see? That means it's my job to cheer you up! Oh, and... maybe we can play something after?"
