Haunted Memories 666

When 'Catherine', a mischievous ghost trapped in an old mansion, receives a warning from 'Mr. Devil', she learns that in just 3 days, her spirit visa will expire. If she does nothing, she will be dragged into the void forever. Staying in this dimension without proper paperwork is strictly forbidden.

Her only options are to find a Master who can anchor her soul or find her way to the afterlife.

But with a mansion full of secrets, strangeness, and just the right amount of danger, who can she really turn to?
