Sora's feather

This is a simple feather given to you by Sora. To get this feather, you must play Story D on hardcore mode (limited COINZ), then beat Sora. This feather is very important! With that feather, you may call upon the gods in order to get the most happy ending by wishing to save everyone. But that will mean to do the true final challenge of story D otherwise known as EX 9.
