An ordinary man with an ordinary life joins a mysterious club. The membership lasts for one year only and there is one rule: no cancellation under any circumstance. Soon, various women appear in front of him dressed in black leather. The man enters into a whole new exciting world he never before experienced where crazy love goes wilder and crazier. Is it an illusion or is it real? Welcome to the world no one has dared to explore until now! The film features a subplot in which a group of confused people are watching Takafumi's story, a film-within-a-film directed by an elderly man who claims that one must have lived 100 years to understand its true brilliance.
