There is no nudity in the film. Subtle joking references are made about Lupin's on-again, off-again romance with Fujiko Mine, and there is a flashback scene showing Lupin grinning leeringly as a woman sits in his lap at a casino.

At the end, Clarisse gestures that she wants to share a passionate kiss with Lupin. Lupin demurrs, instead kissing her chastely and platonically on the forehead.

Lupin is practically a playboy.

Lupin does accuse the Count of being a pedophile (in both the Japanese original and English translation) during the wedding sequence, though the character seems to have no sexual designs on Clarisse (who is depicted as being in her middle teens), instead just wanting control of the treasure.

There is quite a considerable amount of gunplay and swashbuckling fighting action, but relatively little blood. Only two scenes of note are in the film. In one scene, as Lupin is about to escape with Clarisse, he is shot down and gravely wounded when the Count's men open fire with a machine gun. A trickle of blood runs from underneath Lupin's unconscious body.

Lupin is thrown into a catacomb with thousands of rotting corpses.

When a heavily bandaged Lupin interrupts a forced wedding of the villain and the princess, the villains' guard impale him with multiple swords and then turn to kill his comrades. However, that Lupin turns out to be a dummy with a remote controller loudspeaker, which explodes and scatters counterfeit bank notes while the real Lupin in disguise elsewhere makes his move to snatch the critical rings the villain needs for his scheme.

One of the count's bodyguards gets violently squashed by a giant clock tower gear. However it is not shown in full detail, since it cuts away just as the gear squashes the man.

There are some uses of the words "Chikusho" (roughly "damn it") and "Kuso" (literally "shit").

The Manga Entertainment dub of the film has frequent usage of words like "Bastard", "Bitch" and "Shit". It's still more tamer than most of Manga's other Anime dubs though.

The Streamline Pictures dub has more milder profanity than the Manga dub, with words like "Damn" and "Crap" infrequently used.

Daisuke Jigen is almost always seen with a cigarette in his mouth, and many of the other characters smoke to excess as well (Lupin's car's ashtray is shown to be full of cigarette butts). Lupin, during a sequence where he is trying to gorge himself to get his strength back after nearly dying, is seen to drink down an entire bottle of wine.

At one point, Lupin is dropped down a trap door, seemingly to his doom to the girl's horror. However, a ring he gave her before proves to be a disguised communicator and he reassures her that he wanted to be dropped, the situation is under control and he will be back to rescue her once he finishes his business below.

A large part of the middle section of the film is taken up with Lupin and Zenigata trapped in an oubliette, where the remains of many who had tried to discover the secret of the Counts of Cagliostro had breathed their last are scattered. One part of this sequence has Lupin and Zenigata drerssing up skeletons in their clothing to scare pursuers.

Another potentially frightening scene is one in which the Count's minions attack Lupin and Co.

The film's look and feel is toned down than all of the Lupin the Third films, but it is still darker than all of them.
