This is a sex comedy about a few people staying in Tokyo who are somehow related to each other. These include a nerdy freelance writer, a charming pimp, a karaoke bar assistant who imagines that he is a superhero and three porn actresses: a beautiful young lady, a middle aged woman and a chubby lady.
Thought the theme was very similar to that in "Air Doll" with a more in-depth study of the characters! The comedy is a little bit crude but the fantasy sequences were very well done!
