DON'T READ THIS IF YOU HAVEN'T BEAT THE GAME YET AND DON'T WANT TO READ A SPOILER.

Ok, so I broke Ori-San's sword and beat the game. However, if you don't fight him and let him kill the guy, then the game still ends. I went back and didn't fight him and I didn't get any kind of alternate ending movie. Is there any way to see an alternate ending without having to start a new game from scratch?
