Perfect look

Exploration Stage: Wonderful Cat Cafe
From: Madame Miyuki
Description: The spirit of the kitten has yet to appear. It may not be an evil spirit that the kitten fears, but something of this world looking for the kitten's mate. To pretend to be a cat spirit, you need to be in disguise. Can you find our special obsidian masks?
Completed: You have found an obsidian mask! Look at the inlaid opal. This is a gemstone that creates an illusion. Its power strengthens the aura of my soul and makes me look like a ghost. Nope, this is no good either. Why can't the spirit of the cat come out?
