Ryozo Munakata Research Document. The Himuro family rituals.
"Secret Rituals of the Himuro Family
Many rituals and customs have been passed down through the generations of the Himuro family. Most of them are lost. The only things we have left now are some documents that record these rituals as a legend.
Hardly any of the oral history remains. This is because all Himuro family members are dead, and those who were close to the family have kept quiet about the ritual.
One ritual in particular, performed on December 13th, is shrouded in mystery. People who lived near the mansion stayed inside on that particular day, and even now, it is considered bad luck to leave the windows open on that date.
I can only assume that this is due to the cruel nature of the ritual, but the truth remains unknown."

Assistant Hirasaka's Notes 2 - Anxiety about Himuro assignment
The more I find out about Himuro Mansion, the creepier it gets. I'm sure it's the perfect subject matter for Mr. Takamine's next book, but, to be perfectly honest, I don't like this assignment one bit. It gives me a bad feeling...
There's no way I want to go to that mansion. But it's my job, right? I guess I'll have to go. And I wouldn't want to waste the chance to work with Mr. Takamine just because of a little bit of uneasiness, either.
It doesn't help I have this sixth sense for the supernatural, either. There's such a thing as knowing TOO much, sometimes..."

Assistant Hirasaka's Notes 3 - Seeing the woman in a white kimono
"September 10th, 8:00 pm
I clearly saw the image of a woman, in front of the mirror near the entrance. She had long hair and a white kimono. There were ropes tied to her arms and legs, and she dragged them along when she walked. I think I heard Koji talk about something like that, too.
There's something VERY wrong about this mansion."
Ryozo Munakata Research Document. The Secret maidens
"The Mystery of the Rope Maiden
Among the few documents found on the ritual, mention of the 'Rope Shrine Maiden' is made many times. Her arms, legs, and neck are bound by five ropes. However, no documents discuss the role she plays in the ritual.
One theory is that she is a sacrificial lamb, but I find it hard to believe that such a cruel ritual was practiced."
