Lupin is forced to give up his life of crime when he encounters Michael, a young boy who demonstrates that police computers are able to predict his every move.

His retirement is short-lived when his colleague Jigen learns the location of the giant diamond called the Super Egg which was stolen from the Three Masons,[d] a sinister secret society.

The virus causes the US and USSR to prepare their nuclear missiles for launch, but Lupin helps Michael to halt the computer program and avert a global disaster.

One of his best known techniques "Postcard memories", also commonly known as "Harmony" involved adding painted lines to a cel to give the appearance of a watercolor effect and provide visual impact with minimal animation.

[16] Manga Entertainment UK released an English dubbed VHS as Goodbye Lady Liberty in the United Kingdom on 9 September 1996.

[19] Reviewing Liberty for Manga Mania, John Spencer felt it was a "rather routine television movie, with none of the flair and style of the previous films".

[20] Lupin expert Reed Nelson expressed that although Liberty is superior to several of the specials that followed it, it suffers from uneven pacing and a climax comparable to The Mystery of Mamo.
