Angel of Darkness / Injû kyôshi - jissha-ban (1995)

The college students of Shibuya seemed so innocent until a sex depraved demon unleashed the carnal desires of their possessed teachers! Now its writhing tentacles are about to teach them a lesson of desire and ecstasy that they might just not survive!

Buxom college girl Miki and her voluptuous friends Eiko and Ryoko love living the wild life. Sparkling gems and fast cash are the name of the game and they're not against mixing in lots of sex to get the best out of their young lives! Whether it's breaking the school rules by prostituting at night or selling their panties at local stores, this oversexed group of women always get what they want, when they want it.

When a mysterious tentacle demon begins stalking the streets of Shibuya in search of young women to satiate its beastly desires, the small group of friends might just uncover enough pleasure to kill them! Can their professor, Mr. Tojo, save them by getting them to change their wild ways before it's too late? Or could his real interest in the women be more than merely professional?
