Notes for a C-Class Esper

C-class esper Kayden Wolf is a man unraveling. Following the tragic murder of his wife—who also served as his guide—by the elusive serial killer known only as the “Guide Killer,” Kayden teeters dangerously on the edge of going rampant. Consumed by grief and rage, he rejects every offer of assistance, becoming a volatile threat to himself and those around him. With no other options left, authorities intervene, forcing him into a mandatory partnership with Jupiter Balerix, an S-class guide whose overwhelming abilities are the only thing capable of stabilizing Kayden’s deteriorating mind. Together, this reluctant pair embarks on a dangerous investigation to track down the “Guide Killer” and bring them to justice. However, as they work closely together, the boundaries of their professional arrangement begin to blur. Despite the heavy weight of his mourning heart, Kayden finds himself increasingly captivated by Jupiter—a much younger, strikingly alluring guide who exudes a quiet, magnetic charm. Rather than maintaining a safe distance from the grieving esper, Jupiter shows no intention of pushing him away, setting the stage for a deeply complicated bond forged in the shadow of vengeance.
