The next morning, the group is on their way to visit Mount Hiei's castle. When they get to the castle, they find that it's late and they have to wait in the dark for a long time to get in and out of the castle. They're worried that they won't be able to see everything that they want to see, so they're going to have to stay up all night to do it. When the group gets back to the hotel, they realize that they haven't slept all night, and that they'll have to wake up early the next morning to get to their destination.
