Rich? Need a place to keep your attractive but easily misled daughter? Then St. Michael's Academy is the school for you! Nestled on a remote island, it's the perfect place to keep your girl away from temptation as she learns about class, elegance, and refined tastes. Of course, that also makes S.M.A. "Hell on Earth" for a girl like Fumio, who'd rather go to Tokyo U. and eat junk food. Fortunately, Fumio soon finds two kindred spirits in the form of Kazune and Yuzuko, who also groove on cheap ramen and trashy novels. Unfortunately, a lot of weird stuff also starts to happen: the school is targeted by Italian kidnappers (or are they pirates?), the head nun goes a LITTLE crazy... and the girls gain superpowers. It only makes sense for our heroic trio to track down the villains and bring them to justice, right? Get ready for an educational experience like no other as the bad guys get schooled, schoolgirl-style in ARCH ANGELS!
