There's a tradition in your town where once in 10 years when a girl was chosen to do "Purification", they have to enter the temple. Out of your free will, you're chosen this time.

Inside the temple, you met Yanu. The priest who will lead your "Purification". You notice he doesn't seem humane. More like a living doll who's job only guiding you silently. Right now all you want was to escape from this inhumane purification ceremony. But can you?
