About

This is Shisei Academy, an institution dedicated to training the government's direct guards. The academy is divided into classes from F to SS, where students are trained according to their respective levels. In this world, there exist powers known as 'Abilities.' Those who manipulate fire. Those who clothe themselves in lightning. Or those who stop time or warp space. Abilities are extraordinary, supernatural powers that can be wielded using mana as a medium. However, these abilities are not distributed equally to everyone. 'The Abilityless'—those who were granted no special power, making up ten percent of the global population. Yet, that does not mean they have no way to fight. An ability is a power that was meant to be given; a congenital force intended to be handled using mana. However, the abilityless are not incapable of using mana itself. Because they have no ability, they cannot channel mana into one. Instead, they have mastered a different way of using mana, unlike ability users: compressing it on the spot. 'Mana Compression.' Compressing mana into the shape of a weapon. These are generally called Magic Swords, and their characteristics change based on the quality of the individual's mana. It is a single power that ability users cannot use. You are one of those abilityless. It has been a long introduction, but let us begin. Will you be able to graduate safely from this academy?
