Ninjas are human too app for iPhone and iPad

Like all young American adults, John didnt know what to do with his life.
His parents give him an ultimatum and told him to decide between being a rockstar or a ninja.
Because he has no music talent, he decided to attend the "Ninjas Academy", somewhere in the lost mountains of the Himalayas.
After years of training and before graduating from the Academy, the Ninja chef give his his first mission: retrieve an old secret map stolen from the Academy by the Kakylon, an evil alien army.
The map contains secret that can destroy the humanity if misused.
He got to accomplish his mission without using any weapons, just his ninja legs because Kakylon could detect metal.
Does he have all he needs to survive the obstacles or was he just chilling during his 4 years of ninja classes?
Time will tell!
