PlayStation Horror Sound Novels

In direct contrast to the Super Famicom's somewhat paltry selection, there is a fairly healthy number of horror-themed sound novels available on the PS1. Retrieving information on some of these is difficult due to varying obscurity levels and virtually no English language coverage, so any information you may have on these titles would be appreciated. This list is largely considered finished. If you have any relevant suggestions, feel free to send them my way. Thanks to jenny for translation assistance with certain titles.

Consider the situation: you and an apparent friend are working on a stand of some sort for an upcoming school festival. You spend so much time on this task that, by the time you are 'done', it has become late; the windows reveal that darkness has fallen upon your [Japanese hamlet of choice]. You decide to leave, but find that the ways out have been blocked. The teenage drama than begins to build around you; the students that aren't actively looking for a way out seem to have a tendency to either shy away from you or slug you in the face.
