This 1990 feature from anime legend Go Nagai, creator of Devilman and Cutey Honey among other animated series, is a spirited if uninspired mix of Ninja warrior swordplay, modern yakuza gangster gunplay, and anime-style demons. The mysterious Ninja Dragon is a vaguely supernatural warrior sworn to defend the Nindo clan. He dedicates his sword to Shinobu, the schoolgirl daughter of a yakuza lord, and just in time. Upstart gangster Ranjuji, a hulking thug with demonic eyes, massacres the heads of rival criminal families and kidnaps young Shinobu for his bride. There's plenty of flashy swordplay and bloody violence (blood spurting from wounds like a waterfall, limbs ripped from bodies, and a man's face ripped from his head like a banana peel), and the massive battle between the Ninja Dragon's trio and Shinobu's army makes up for sloppy technique with vigorous choreography and a rush of activity. Apart from a few sidelines for unnecessary exposition and a ridiculous contest that turns Ninja warriors into World Wrestling Federation wrasslin' chicks, Nagai keeps this silly, simplistic Japanese comic book B movie zipping along with gusto. It won't leave much of an impression, but it's a fun 70 minutes of brainless action. --Sean Axmaker
