The Ninja Epidemic

You duck behind the couch and wait. After a few moments you see the shadowy figure enter the room from the hall. He is all dressed in black and wears a mask. There is no mistaking that he is a ninja.

You no longer tdoubt the events of last night. It was indeed a ninja that was hit. Ninjas are in town, but why? You dont think much on it, but you mentaly state the obvious conclusion that whatever the reason, ninjas in town trying to kill people is not a good thing.

As of yet, the ninja does not see you. He has equipped on him several shirukens and a katana sheathed at his side. He walks silently. Had you not been watching for him you would not have known he was approaching. Near you are a remote control and a telephone. Not the best of weapons, but it's whats available.

What do you do?
