You are Mega-Man, Dr. Wily has sent 8 machines after you. You defeat each every one of them except 1, Shadow-Woman. You get to the place Shadow-Woman was, and get to running and jumping on many platforms and attacking as many enemies as you can. You eventually reach a steel door and open the door to see Shadow-Woman, with a Big Shuriken/Shadow-blade in her hand.

S-W: "Hm. You're here as I expected. Now, You've outlived your time! Let's go!" Gets into a Ninja-Stance.
