The earthquake is caused by the unstable nature of the gem fragment, and the scientists decide to keep it in a simple cabin for preservation. They also decide to put it back in the storage cabin so that it won't be exposed to the elements for too long. They're just about to celebrate the anniversary of the school year, so they're having a little bit of a party. Everyone's having a good time, except for Cai, who's in a bad mood. He doesn't know why he's there, but he thinks it's because Cai's sister, Tensho, has been teaching him random things. Cai tells everyone to stay calm, because the earthquake just happened. He's not sure how he feels when he looks at the gem. He feels dizzy when he touches the wall, and then he blacks out.
