Yes, this films reminds me somehow of the 1970's-80's Pinky movies or the slick sexmovies that Nikkatsu produced, with new
directors getting free hands to direct the films in whatever way they wanted .... if they still had a lot of sex in them to satisfy
the "raincoat" crowd. Some famous directors started their career that way.

"Girl's Blood" is an action female fighting drama with nudity and softcore lesbian sex and it's nicely shot and looks really slick,
a Neo-Pinky film maybe .... or is it a Parody over a sleazy artmovie ? There are a lot of serious talk between the 4 girls and we're
shown their friendship and of how they bond and also have a lesbian love affair, and then there are a lot of martial arts fighting
in nicely shot action scenes. But - also there are lots of scenes with the girls taking showers, hosing each other down with water
(the director seems to love the hose) undressing and having lesbian softcore sex, so this probably is an exploitation movie.
But the girls are beautiful and i have to admit that the softcore lesbian sex scene was a bit arousing (or maybe i'm a perv)?

There's an ongoing underground all-girls MMA fighting gala in an abandoned school in Roppongi - called Girl's Blood.
We get to follow 4 of the girls fighting there: Satsuki (Yuria Haga), Chinatsu (Asumi Tada), Miko (Ayame Misake) and
Mayu (Rina Koike). Satsuki is unsure of her sexuality and finally comes out as a lesbian, Chinatsu has left her abusing
husband (Hideo Sakaki) and finds her new love in Satsuki, Miko is a S&M Queen that likes to whip people and Mayu
is just a sweet girl with a young face.

The fights are staged like a US wrestling gala with the girls wearing funny clothing and most of the girls are amateurs
and can't really fight for real besides perhaps mudwrestling. The happy audience doesn't care but enjoys the show.
But some girls can do some real MMA moves and when the Girl's Blood Team is challenged by the Ando Karate Team
there are some "real" fighting also.
Yeah, two Karate schools fighting it out, that's a classic element from old 1970's martial arts movies, but this time
without a Sammo Hung, Jet Li or a Yuen Biao and with sexy girls instead. Yes, Sexploitation trash, if slick it is.

The film is presented in anamorphic widescreen 1.85:1 with a 2.0 stereo japanese audio with english subtitles, trailer
