I'm stuck on the 777 concert boss right now. I can't attack because everything is dark. All forums and videos say to have Shiki go on the rafters to kill bats. What bats? How can I see them without the second screen?
Pretty sure when you summon her the screen will change and you will be up of the rafters where you can take out bats on the lights. Use the existing forum thread next time you have a question.
