When I am in the Tochika dungeon, the cave, I defeated the first challenge, or trial, and can find no more people to defeat. Also, Nayata won't allow me access to a certain area, where the Goal is. She says that it is not the way. I am stuck. Can anyone help? Has anyone gotten past this point?

I had the same problem second time through the game it's not a glitch the other two ppl are hard to find but there in there. she won't let you through that area yet because thats where the final challenger is just keep looking and you should find the first 2.
