The Ninja Epidemic

You step out of the car and walk over to the body slowly. A pool of blood is spreading around the ninjas corpse. You nudge him with your foot. He is indeed dead.

Suddenly, the black forms of ninjas jump down at you from all around. There must be half a dozen, you figure. Two of them are attacking Ricks car, while the other four are near you. Rick is screaming for you to get back to the car.
