Tired of watching the same boring human condition routine since the dawn of time, the Mo0n suddenly woke up and tore pieces of our planet earth apart. A bunch of unfortunate people, who also got lifted up during the cataclysm, were blessed by its celestial Highness and received incredible fighting powers. They became... the Ninzas!
To ensure that its champions will never cease to fight against each other and keep the entertainment at its best, the Mo0n promised to fulfill the dearest wish of the Ninzas who could earn its respect.
