I Was a Teenage Ninja (2008)

A teenage swordswoman fights evil with the power of Nin-TIT-Su in I Was a Teenage Ninja (2008) Sora (AV star Saki Ninomiya) is a 19-year-old martial arts novice who doesn’t yet know her tight, teenage ass from a ninjaken. But while her superiors are away aiding clashing factions in war-torn Japan, Sora stumbles onto a plot to kill a famous priest. With no other ninja around to protect the holy man, Sora defends him herself with the power of body, mind, and spirit...but mostly just her body. Sora and her nubile Nipponese pals are using their seduction skills to save the day, and it suits Mr. Skin just fine. Saki and Lemon Hanazawa both bare bite-sized boobage when their kimonos are ripped open by baddies, and Motoko Sasaki shows snookers and seat meat getting her butt eaten by a randy man of the cloth. These cunt-fu fighters really put the "ass" in "assassin"!
