Everyone has accepted rin as the rightful heir to the throne, and the larks will be there to support him. They'll go to the theater for the ceremony, where rin will be officially recognized as the heir of the throne. Everyone is freaking out, because they thought they were going to be in an auditorium. But they're actually in the tower, and rin is going to take over. He'll be able to do whatever he wants with the cloaks, and they'll all be together forever.
