Seiken Tsukai no World Break

Seiken Tsukai no World Break follows Akane Private Academy, where students who remember their previous lives are trained in Ancestral Arts to defend the world from Metaphysicals, monsters that appear without warning. These saviors are divided into two groups: the kurogane, who channel prana to summon offensive weapons, and the kuroma, who wield magic. Moroha Haimura enters that world as a seemingly ordinary student, but his life changes during the opening ceremonies of the school year when he meets Satsuki Ranjou. She remembers a past life in which she was his little sister, while Moroha was a heroic prince whose sword skills could cut down entire armies. Soon after, he crosses paths with Shizuno Urushibara, who recognizes him from another incarnation entirely: in that life, Moroha was a dark lord with devastating magical power, yet he still saved her from a life of slavery. As memories from two very different lives surface, Moroha is forced to confront the bond between the present and the past while the academy continues its fight against the Metaphysicals. The series blends school life, fantasy combat, and reincarnation-driven drama around the question of what kind of future can be built when old identities refuse to disappear.
