Sister Street Fighter: Fifth level fist" isn't strictly part of the "Sister Street Fighter" series anymore, as it does not continue the story of the same characters, but it's good fun for its own qualities. Etsuko Shihomi plays Kiku Nakagawa, daughter of a family who wants to see her married soon, but she prefers to attend her martial arts lessons and kick some butt. When drug smugglers kill Jim, brother of her friend Michi, and instead of waiting for the cops, Michi and Kiku take revenge into their own hands. The gangsters pretend to run a film studio and make movies by daytime - an opportunity to ridicule the circumstances of cheap, fast productions. The fourth and final movie of the "Sister Street Fighter" series makes good use of its comedy elements, from the crazy film crew to Kiku's father who secretly helps her, but would be happier if she was living more traditionally (he is a kimono salesman) and first of all, he is very afraid of her mother.
