Six months had passed since the students had studied at the Piqmentia Grand Academy. They should be given a midterm exam. But considering the successive incidents that occurred in the Dwarven Kingdom and the Elven Kingdom, they were exempt from the test.

Every semester, students and teachers will have a vacation together. They didn't choose to go outside the human region because they still couldn't forget the earlier incident. After Merlick had a meeting with the teachers, they decided to take a vacation to the Cirlus Kingdom territory. An archipelagic kingdom whose most of its territory is the sea. King Raghnall was happy to receive their visit to his kingdom.

The students should be at the academy as they will be leaving for the Cirlus Kingdom for a vacation together in a few days.

In the morning, Princess Iris and Clara were walking in the hallway of the girls' dormitory. They had just returned after finishing their morning exercise.
