The group leaves the sun-moon empire and heads east toward the students' exchange location. The hallmaster tells the deans that his grandchildren have been safely escorted back to the academy. The deans agree that it is time to say goodbye, but they do not want to rush. They decide to find a good restaurant and eat there. The senior brother tells the group that they must change the way they call each other. He suggests that they split up so that they will not be in danger if they go with the other. The elder brother says that they have reached the "sky soul empire" and that they should not wait for the other students to return. The sky darkens, and the old friend asks why they are still together.
