Kindaichi Shounen no Jikenbo Specials

Kindaichi's detour to a hot spring goes sideways when the crew lands at a dilapidated hotel with a nasty history, someone died here six years back, neck punctured, villagers blamed a vampire. Now guests are dropping, Miyuki gets attacked by something with fangs, and Kindaichi's got to figure out if he's chasing folklore or a very human killer.
