Hey, folks. I got to the colosseum and completed the first round. And for the life of me I can't figure out how to start the second round. I've talked to all the NPCs and visited both gates, as well as the paths that just end in balckness. I've spammed buttons all over the place. But I just don't see how to trigger the next event.

I know it's something stupid simple that I'm just not seeing. >.<
