Ninjatown is situated in something of a bad spot. It can't be fun to live with an active volcano called Mount Feroshi on one side and an evil-ridden forest called The Dark Forest on the other.
Fortunately Ninjatown kids take self-defense classes as soon as they are out of their diapers. They are skilled Ninjas even before they come of age. This is a good thing as evil-doers are threatening to overrun the town. It is your job to give the Ninjas the strategic guidance that they need to save their town from destruction.
