Kindaichi Shonen no Jikenbo: Kyuuketsuki Densetsu Satsujin Jiken

Miyuki receives an invitation from her friend Hikune Youhei to the themed inn called "Ruins", located in a virtual ghost town haunted by the legend of a vampire. However, what Kindaichi had originally dismissed as spooky rumours with no basis became horribly real when their fellow guests staying at the inn are found dead one by one, with their bodies drained of blood and wounds in their necks that resembled vampire bites.
