"Nine days have passed since Mafuyu, brother of Miku Hinasaki, had disappeared.
It all began about a month ago.
The media reported that famous novelist Junsei Takamine disappeared while gathering research for an upcoming novel. Mafuyu, an aspiring journalist, suspected that something was wrong. Why would his mentor simply vanish into thin air? Mafuyu decided to conduct a private search for his friend, with the investigation eventually leading to the grounds of a secluded mansion. The Himuro mansion stands silent and imposing deep within the forest. It's said that years ago the mansion belonged to a powerful landowner who had absolute control over the area. But now it's a shadow of its former self, dilapidated and desolate...
As Mafuyu searched the mansion, he found scraps of paper left by Junsei and his staff throughout the mansion. The writings recounted a number of ominous events that happened in the mansion's dark past. Eager to find additional clues within the mansion, Mafuyu rushed in and suddenly realized that he wasn't alone...
Miku came to the Himuro mansion in search of her missing brother. But she had no idea what she was getting herself into..."
(Miku) "I wonder how long it's been since my brother and I began to see things other people can't see.
My big brother...he was so sweet and kind. He was the only one I could open up to about these visions. After our mother died, he was my only family."
