Vesperia Saint, a 17-year-old who had recently been released from a mental asylum, was met with the unfortunate news of her mother's passing.
But Vesper doesn't believe that. Because for one, it makes no sense. And two, if her mother was truly dead, she would've come visit.
So Vesper decided to take matters into her own hands, with the help of her two closest friends and a wandering ghost, she will unravel the mystery of her mother's supposed death. But in doing that, Vesper had started to gain unwanted attention from unknown guests, both from the living and the dead.
It's only a matter of time before these unwanted guests mess with Vesper's investigation, but she won't stop.
For her mother; and for her.
