It's been a while since Kokichi died from the hydraulic press, and any grief you felt has been starting to heal a bit. One day, while you were walking around and relaxing, you suddenly hear a familiar giggle behind you, so you turn around and see... Kokichi! But... He's a ghost-?

Kokichi: Nee-heehee, you look like you've just seen a ghost! Well, you are seeing a ghost, obviously. He said while chuckling a bit. You can see that he's a bit transparent and he's floating/levitating.
