I havent heard anyone mention this boss fight anywhere on this site, but if anyone knows about it please answer it as soon as you can. After scaping from the cage thing in Alexandria castle and being reunited with you're other party members, you can fight this boss in the library which is to the left of the castle's entrance. You have to press X in front of the bookshelf far to the left. Its tough defeating this boss since he uses paper storm and it deals a lot of damage.You also only have 30 minutes and its not enough because you also have to rescue Garnet. I need to know how to defeat him fast!! There is some kind of secret to defeating him but I can't figure it out.
