The deduction battle between the two shall be televised in order to boast the declining tourism of Okinawa. Heiji, Conan, Ran, and Kazuha head to the island to investigate and are accompanied by four TV station employees. They find the mysterious message as "The sleeping place of a princess shall be Kō and not Otu" where Kō and Otu could stand for multiple meanings.

When they prepare to head back, they find out the captain left with the boat, stranding them on the Onikame. They decide to wait in an abandoned house until a rescue boat arrives. (Source: Wikipedia)
