The Mor Empire - Mero [English]

The story takes place in the Mor Empire. It is an empire that has absorbed the surrounding kingdoms. To enforce peace in the conquered lands, the second-born child of each important noble must spend their high school years at the Imperial School of Mor (a legendary king who is said to have founded the kingdom of Mor before it became an empire). Mero is the second son of the King of Sel, an archipelago kingdom on the other side of the world with customs very different from those of the empire. The kingdom requested to be integrated into the empire three generations ago to avoid being conquered by its historical enemies. Mero is somewhat reluctant to leave his country, but he knows he has no choice. The empire demands his departure. He will have to cross the seas to reach the western coast of the empire, then pass through several subdued states before arriving at the Imperial School.
