Seiken Tsukai no World Break unfolds at Akane Private Academy, where pupils who remember past existences are taught to wield Ancestral Arts in order to protect against monsters known as Metaphysicals that strike without warning. Dubbed saviors, these students are divided into two groups: the kurogane who channel their prana to summon striking weapons, and the kuroma who manipulate magic. While the kurogane focus on physical offense, the kuroma excel at defensive spells today.
