Fuck Fellini! Balls to Bicycle Thieves! High art be damned - this is what we want. Tattooed biker chicks armed with switchblades, sadistic schoolgirls smashing skulls, shower scenes, catfights, juvenile delinquent bitches on heat and much more. Japan has provided us with some of the most fucked-up movies on the face of the planet, and in this wonderful boxset we have four more outrageous 1970s exploitation flicks.

In Girl Boss Guerilla, a female biker gang fights for turf against a rival Yakuza mob who don't appreciate their cavalier approach. Imagine Switchblade Sisters with more tits, ass and torture and you're some way there. Terrifying Girls' High School: Lynch Law Classroom is a sordid little tale set in a reform school for girls, ironically named the 'School of Hope'. The teachers are perverts, the pupils psychotic and the school rapidly going to hell. A gang rules the school with an iron fist, forcing one unfortunate soul to do 50 press-ups with a light bulb up her snatch. Another victim has electrodes attached to her nipples, and one more is hooked up to a bizarre contraption that slowly drains the blood from her body.

More catfights ensue in Criminal Woman: Killing Melody, plus topless go-go dancing, chainsaw abuse, the obligatory torture scenes and shootouts. Finally we have Delinquent Girl Boss: Worthless To Confess, which only really springs to life in the splendid swordfight finale, with tattooed sluts versus Yakuza gangsters. All in all, this boxset is just what the doctor ordered - exploitative, sleazy and entertaining as hell. It's available in strictly limited quantities, so grab one while you can.
