The Southern Cross Looked Like Diamonds

In the eastern part of Rabaul, which saw some of the heaviest fighting of the Second World War, lies a cross which marks the location of Captain Cook's treasure. Lupin and company, who've come looking for it, find themselves suddenly under air attack by Zero. They are rescued by a man called Samejima, but he takes Fujiko hostage in exchange for having them get the A-bomb away from the Zero. It seems it was a holdover from the Bikini Atoll testing days, but Sergeant Kimihiro of the Imperial Japanese Air Corps is guarding it with his life, recalling the ghosts of both the Japanese and American soldiers.
