How do I open up this tournament? I've already passed the first three (Pain and Panic, Cerberus and Titan Cups).
I've looked at gamefaqs.com and there is nothing about how it opens. I go to talk to Panic in the Underworld Entrance and it's not listed there. I'm at level 67 and basically done with the game except to level up and do the final battle.
This tournament and Gummi Flight is all I really have left to do.
