Kotarou was pretty much supposed to be your average boy, worried about the pressures of education while enjoying a simple life with his friends. Much to his despair, he one day finds the overly cheerful Misha at his door, asking to be friends out of nowhere. Even more shocking is that Misha is an apprentice angel, yet she does more bad then good. Along with Kotarou's school friends Takashi and Koboshi and the so called devil Shia (once again being able to do more good then bad), the group of friends spend their days getting into all sorts of adventures and troubles. Based on the manga by Koge-Donbo.

During a monster attack on the city, which is something that happens quite often, Silk and her two friends try get close to the attacking monster for a better view.

Feeling sorry, UFO-man blames their death on the monster and promises to bring Silk and her friends back to life by lending them his power but the catch is that they now have to become the city's protector as well.
