Shiho has always been aware of her dissimilarity. Her strength surpasses that of an average human, and controlling her emotions, especially anger, poses a challenge. Consequentially, she avoids socializing. One instance, just before her middle school graduation, she unbridled her emotions, unleashing a destructive rampage that injured several students, and teachers. The news briefly reported this mishap until an organization, the Sorcerers, intervened, hiding the incident. The Sorcerers disclosed her lineage, as a descendant of demons. Their role is to regulate the demons, well-known for their inability to master their emotions. The demons' task is to find a scabbard, an individual who can stabilize their emotional state and, if need be, eliminate them when they lose control. If unsuccessful, the Sorcerers carry out the extermination. Will Shiho succeed in finding her salvation?
