First enter the debug code, access the debug screen, hit "charge item", then "kawarimi", then hit FULL (this item is the "resurrection leaf", Ayame or Rikymaru will have this item so that if they are atacked by an enemy they won't kill them and the game will not end if they are killed). You will be able to play as Onikage in the lever witch he apears:3,6,9 and 10. Enter the debug screen again, choose "layout enemy", then "add", then choose "NINJA", then "pad 1". Then go to the debug screen again, "layout enemy", then "go". Walk in any direction far enough to let the normal play screen reapear Onikage. Now enter the debug screen again, hit "layout enemy", then "select camera owner", then hit the last number the apears on the second page of the "camera owner screen" (except on level 10 witch is number 23 because Onikage is not the final boss of this level). Now you will be able to play as Onikage and see him as if you were playing with Rikymaru or Ayame. You can also add any item to Onikage, except the "grapling hook", but you can use the item "the world" instead, witch will move Onikage to the spot you are amming at. This code can also be use for Lord Meyo (number 24 on level 10 only) or any other enemy that you know the "camera owner" number.
