Lupin III: Elusiveness of the Fog

On the ocean floor, Lupin is once again seeking a treasure hoping to get on Fujiko's good side. As Zenigata chases them on sea and land, people around the gang begin to vanish mysteriously. The fog rolls in and Mamo Kyosuke appears in a burst of light; he claims to be from the future and seeks revenge on Lupin III for what Lupin XIII has done to him. (myanimelist.net)
