The device shown here was left by Kunihiko Asou. He used it to substantiate the existence of and communication with the Spirit World.

He was a brilliant scientist and philosopher and by appropriating Western culture in the late 19th and early 20th centuries, he combined new technology with his theory on the "Spirit World" to prove it's existence.
It is said a few of his devices were able to capture an "unbelievable" existence from the Spirit World, but posthumously, from that singular beginning, his devices became a fashion item among dilettantes and were scattered about the country.
One such device is this projector.
Having completed the experimental stage of the "Camera Obscura" (a camera that photographs the other world; see above), he created a screen upon which to project special images captured on the film.
The records say that images were projected that could not be seen when they were photographed.
Note:
- Due to a translation error, the title of the book as Rei picks it up off the shelf is erroneously given as "Occultism".
- While viewing this note in the menu you may view an image of the Camera Obscura by pressing the O (circle) button.
