Living with his aunt Sakuri, Kugaya is a teenage student at his high school. His kendo coach, Narugami, has been persistently urging him to join the kendo team. However, Kugaya's life takes an unexpected supernatural turn when he meets Takemi - a new girl. Suddenly, he finds himself embroiled in a grand battle with demonic "intruders". Along the way, he must grapple with themes of reincarnation, repressed memories, a Holy Sword, and an entire clan of skilled swordsmen. For a high school student, it's all too much to handle!
