Early pinku.
Second Pink film by Wakamatsu
A failed science experiment gives a librarian the ability to turn into a gaseous substance. He goes on to rob banks to fund his dancer girlfriend's career, killing those who interfere. Now Tokyo's most wanted criminal, can authorities stop him?
This was the pink film debut of Masayoshi Nogami, one of the most popular and prolific actors in the genre. Over the next 47 years, until his death in 2010, he would appear in hundreds of the films, and direct at least eighteen.
