A locked room mystery that actually uses its gothic setup instead of treating it like window dressing. Kindaichi walks into a hotel where the supernatural threat feels real to the people trapped inside, even if logic says it isn't, and that tension between what might be true and what can be proven becomes the actual case. The vampire is a red herring wrapped inside a murder, and watching him untangle which is which without letting the atmosphere collapse is what makes these specials work.
Kindaichi and his friends take a wrong turn on their way to a relaxing hot spring getaway, instead stumbling upon an abandoned hotel that time forgot. The locals whisper about the vampire that haunted these halls decades ago, a creature supposedly killed by villagers six years prior after a young girl was discovered in the cellar, drained and marked with bite wounds. The stories feel like urban legend until one of their group is found dead with identical puncture marks on the neck. When Miyuki is attacked by something with fangs in the darkness, the nightmare stops being folklore and becomes terrifyingly real. Now Kindaichi must uncover whether an actual vampire walks these corridors or if someone is using the old legends as cover for a very human murder. The truth lies buried in the hotel's dark past, and staying alive long enough to find it means confronting both the supernatural and the secrets the locals have kept hidden away.
