One day you were in a mansion with your group members Vivi, Arthur, and Mystery the dog (kitsune), as you were separated. You ended up discovering a secret stair case that lead to a lair

You see there’s purple carpet that lead to a coffin that glows Magenta. As it slides open revealing a ghost with a skull for a head. As a magenta floating flame lights the room and gave the ghost pupils and hair, as he glared down at you angrily with an orange heart on his chest.

What do you do?
