The Lupin gang is once again dragged onto a wild treasure hunt! This time, the objective is a mysterious, small dragon statue that even Goemon's steel-rendering blade Zantetsuken cannot cut. The artifact, which once eluded even Lupin the Third's esteemed grandfather, rests deep undersea inside the infamous Titanic, and is the key to unlocking the mystery of Zantetsuken's almighty strength. A wealthy gangster, Lupin, and Goemon all want the statue for themselves!
