Event 9: Hide 'n' Sheik

In this event, you must KO two Sheik's. The KO will only count if you kill Sheik, not Zelda. Try to give Zelda as much damage as possible without killing her. Once she turns into Sheik, then you can deliver the final blow. Killing Zelda will only make her return to the arena with 0% health. Once you kill Sheik, she is gone for good and will not return to the arena.
