A while ago when I posted my 100% route WIP, Jiano mentioned that I needed to heal Koume the same cycle I beat Woodfall for archery. I asked him to check, he did, and he said I was right; that you don't need to heal Koume for that.
So I went on routing the entirety of 100% all the way to the beginning of the final dungeon, and when it came down to play test it, this is what happened:

This wouldn't be an issue for 100% if I could trick the game into ending the minigame, giving me the HP even faster. AKA the fate of 100% SS relies on Razor.
