What happens when you hire a Ninja to steal a secret formula? What happens when that formula is held in a top secret state of the art high security science lab? What happens when that ninja accidentally gets splashed with the secret formula? Well... all of those questions are probably related and answer the question: Where did that giant Kaiju monster suddenly come from? The life of a Ninja isn't easy, with all the stealth sneaking, high kicks, and the other Ninjaery things that need to be done. Now throw in a secret formula that turns you into a big city destroying monster and suddenly you're not so stealthy any more. The job gets even more difficult when you have not one, but two super smart mad scientist after you because they think you stole their formula and send hordes of robots, the air force, and other never before seen science experiments after you. It may no longer be just a job for a Ninja, but it definitely is for a NINJA KAIJU!
