Original title: Kûsô-kagaku ninkyô-den: Gokudô ninja Dosuryû
For centuries, the bloodline of the Nindo yakuza clan has been protected by three magical ninjas whenever real trouble reared its head . After the ninja appear to high school age Nindo daughter Shinobu (Etsuko Araoda) in a dream and gift her a magical protective amulet that she takes with her into waking life, the girl quickly learns why ninja protection can be needed.
Two improbably strong and hardy people are murdering yakuza left and right – the film never bothers to tell us if the victims are part of the Nindo-gumi – as part of some vague yakuza domination to country domination to world domination plan of the also freakishly strong Go Ranjuji (good old Rikiya Yasuoka). Shinobu, though, Ranjuji doesn’t want to see murdered. He wants to marry the high school kid so she can produce “thousands and thousands of eggs” for him, as you do. This really is a job for magical ninja.
This OVA/V-Cinema movie is anime and manga royalty Go Nagai’s only foray into directing live action, and what it lacks in having anything like an actual narrative, it does make up for in cool, cheap, and pretty damn awesome practical effects. Ever wanted to see Rikiya Yasuoka rip a guy’s face off and then lick what’s below? Ever wanted to see Rikiya turn into a thing out of Screaming Mad George’s dreams? Go Nagai has all your Rikiya needs covered.
Visually, there’s a budget conscious mix of cramped frames and sudden bursts of Steadicam, and at least an attempt to provide visual interest in every single scene, even when it’s just letting the camera slowly move from one off-kilter angle to another. There’s a certain amateurish energy to Nagai’s direction here that works well for a film that doesn’t really want to tell anything amounting to a story, and while I wouldn’t recommend this to civilians, if you have any interest in Nagai, or practical effects-based direct to video movies from Japan, or films that include a random scene in the climax where Cutie Suzuki wrestles, unconvincingly, or just films where ninjas fight aliens, you’ll probably have a reasonably good time here. I certainly had, but that’s only to be expected.
