Kindaichi (Animated) Collection

Kindaichi, Miyuki and Fumi are invited to the resort of the Deep Blue Island by Akane, the daughter of the president of the Aizawa Group. A group of criminals infiltrate the hotel to kill the members of the Aizawa Group.

Kindaichi, Miyuki and Kenmochi arrive at the doomed opera house in the pouring rain. There they meet another and last "Phantom of the Opera", who announces a new series of murders.

Kindaichi and the gang are on their way to a hot spring, but get lost and end up at a run-down and sinister hotel. They are told that a vampire used to live in the hotel way back. Someone even died (was found with bite marks on the neck). Six years ago a girl was found in the cellar with bite marks on her neck, and the villagers killed her. When one of the guests is killed and Miyuki is attacked by a creature with fangs, it would seem like the vampire is still there.
