The ruler of the demon world has come, with only his trusty assistant, to conquer the modern day human world!

For his conquest, he's got to fight the Hero of the human world. She's Ichikawa Kyouko, a distractingly pretty, tough, modern-day girl who happened to pick up the giant sword that marks her as the chosen one.
