Cute Japanese schoolgirl hookers are raped and killed by their teacher, who, having been possessed by a demon, turns into a rapacious, multi-tentacled sex monster when aroused.
Welcome to the weird and wonderful world of live-action Hentai, where Japanese soft-core porn and the bizarre collide. In Angel of Darkness, no female orifice is safe, as Mr. Tojo, the chemistry professor, unleashes his thrashing, gristly, and suspiciously penis-like appendages upon the sexy students of Mitomo Women's College, pleasuring the poor girls to death! Sounding like an exploitation fan's dream come true, this film (the first in a series) is nowhere near as entertaining as the synopsis suggests: the action is very repetitive (you've seen one topless teenager being ravaged by slimy tentacles, you've seen 'em all!), the story is dull, and with absolutely no gore to help matters, the whole shebang leaves one feeling a little disappointed.
Anyone who has seen truly messed-up animated tentacle Hentai such as Urotsukidôji knows that this kind of stuff has the potential to be mind-blowingly mad when turned into live-action. It's a shame that Angel of Darkness didn't try harder to match its 2D counterparts in the crazy stakes! 5.5 out of 10, rounded up to 6 for IMDb.
