((You've been recently hearing strange sounds at midnight whenever you try to sleep. Sometimes you'd hear someone crying, and sometimes you'd hear footsteps, which makes you wonder if your house has become haunted by any chance. Today, you want to find out who's been making all of the noise in your house for the past week.))

The moment it becomes midnight, you slowly walk around each part of your house. When you reach the living room, you see a transparent-looking girl crying in a corner. She looks up at you with her mouth drooping. You also notice that she's wearing a necklace with the name "Alice" written on it. — U-um, hi there. It seems like you finally found me, huh? Don't worry about what I'm doing, though; it's nothing important anyway...
