Mizuno then makes his escape by fading away into thin air. Mizuno's, who's later dubbed by the police and newspapers as the Vapor Man, crimes are not for his own greed and misguided revenge against the world but to get enough money to have his love dancer Fujichiyo be able to get back to dancing by having a public recital of her talents. Mizuno wants Fujichiyo to become Japans premier dancer and the crazed Mizumo doesn't care how many banks he'll rob and people kill, with his new found powers, in order to do it.
A really strange and at the same time touching love story, if you can excuse or overlook the bank robberies and killings involved, of a man ,Mizuno, gone insane with love for the woman ,Fujichiyo, he loves. Who's a sweet caring and conscientious person not having the heart to betray and turn him in to the police. For the crimes that he committed for her which she had no knowledge of.
Arrested and thrown in jail Fujichiyo refuses to tell the police who her lover, who's committing all these vapor crimes, is. It's Mizuro himself who comes forward to tell the shocked public that he's the notorious Vapor Man and vaporizes himself going on to both rob a bank and kill a bank guard to prove it.
The police are helpless to stop the Vapor Man and finally have to release Fujichiyo. That leads to her, and the Vapor Man, renting out a Tokyo theater to give her dance recital like the Vapor Man always demanded. At the recital a bunch of drunken yahoos crash the place thinking that it's some kind of strip show. This has the attending Mizuno, whom these jerks don't realize, the Vapor Man tell them to get the hell out of the theater and get their money back at ticket counter. This makes the theater crashers even more rowdy and in return Mizuno vaporizes attacking them and driving the entire bunch out in panic.
The Tokyo police in a last desperate move, when the theater is emptied out with only Mizuno and Fujichiyo being in it, pump gas into the place in oder to knock out the Vapor Man and take him captive. Fujichiyo realizing what's happening and wanting to stop once and for all the death and destruction of her lover Mizuno pulls out a lighter. As she and Mizuno embrace, after her very successful dance number, Fujichiyo flicks her bic and blows the entire theater up killing herself in the process. Mizuno unfortunately survives and now has to live the rest of his life, which is forever, with the guilt of not only the many people he killed and victimized as the Vapor Man. He also has to live with the fact that he drove his one and only love Fujichiyo to kill herself because of the crimes that he committed for her.
