This glitch absolutely rocks! When at the black pearl stage in any mode,pick either Sesshomaru or Demon Inuyasha.To perform the glitch,knock your opponent off the side of the cliff so they fall,now persue your opponent by jumping up against the barrier and holding the x button.If performed properly you will shoot into the backgruond graphics!It's alot easier with Sesshomaru but if you keep at in certain areas on the cliff,Demon Inuyasha will do it to!

Okay, with Sesshomaru, go to Black Pearl,fall off the side, and wait for yourself to come back. When you are on the skeleton bird, do that attack where you jump in the air. You will appear on a rock, and just walk over to your father. You can stand on him! I hope someone likes this glitch. ^^ I did.

Successfully complete mission mode with any team variation.
