Kindaichi Shounen no Jikenbo

Kindaichi is back with another mystery to solve.

Miyuki and Kindaichi hear the story about how Inspector Akechi was a really cool mentor to a young policeman named Kobayashi.

The movie is an alternative version to the "Satsuriku no Deep Blue" arc of the 1997 Kindaichi TV series. Kindaichi, Miyuki and Fumi are invited to the resort of the Deep Blue Island by their senpai Akane, the daughter of the president of the Aizawa Group. A group of criminals infiltrate the hotel diguised as waiters to kill the members of the Aizawa Group. The criminals don't know their boss in person, and they don't know either that he's in the hotel with the members of the Aizawa Group.

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...
