There are two nameless characters who are twins, only referred to as Man of Mystery on Japanese Wikipedia. One who "disappears" and was also after the golden pen that Lupin stole and the other is an assassin.
- The character designs is based on The Castle of Cagliostro however it is Lupin's red jacket from Part II. Fujiko is also a brunette rather than a blonde and wears her disguise rather than the camouflage army uniform. The tone of the game is also closer to the film than the majority of Lupin work.
- The game uses a combination of sprites and videos between scenes, the latter takes up the majority of the disc. As a result, the game is on two discs. On a technical note when using Dolphin and its texture dumping, the video scenes come up in grayscale as a frame buffer while the sprite scenes are in color. The game also runs at a lower resolution ranging from 320x176 to 640x352 outside of the title screen.
