Kindaichi Shounen no Jikenbo Movie 2: Satsuriku no Deep Blue

Hajime Kindaichi, Miyuki, and Fumi are invited to the luxurious resort on Deep Blue Island by Akane Aizawa, daughter of the powerful Aizawa Group's president. The isolated paradise becomes a trap when armed criminals infiltrate the hotel disguised as staff and begin targeting members of the family.

The attackers are following orders from a leader they have never met, unaware that the mastermind may already be among the guests. With the island cut off and murders closing in, Kindaichi must look past disguises, family tensions, and carefully staged clues to identify the person directing the massacre from inside the resort.
