Abandoned at a church in childhood, Master Flare ascended as both priestess and executioner, her early years shrouded in obscurity. By eighteen, she had forged a reputation as one of history’s most prolific executioners, specializing in extradimensional eliminations. Her notoriety arose from a machine-like adherence to duty, executing commands with mechanical precision devoid of sentiment. Renowned for a callous, psychopathic demeanor, she regards others solely as instruments or prey, her actions untouched by remorse. Even toward her apprentice Menou, this detachment persisted—Flare saw her as expendable, a mere tool in her arsenal. Two decades earlier, she conducted a chilling experiment: befriending a Lost One under her charge to determine if executing a companion would spark guilt. The subject’s demise yielded no emotional resonance, cementing her emotional sterility. Eight years prior to Akari Tokitō’s emergence, Flare crossed paths with Menou, the lone survivor of a Lost One’s devastation. Though initially dismissive, Menou’s relentless resolve amused Flare, prompting her to take the girl as an apprentice. Her training regimen crushed many aspirants, driving most to abandon their path. Menou alone endured, bargaining to become Flare’s sole protégée by pledging to fulfill the roles of all who had fled. Flare’s strategic mind engineered decades-spanning machinations, including a plot to wield the Sword of Salt against Ivory—a primordial force. Menou’s intervention to rescue Akari derailed this scheme, though Flare met the altered outcome with characteristic apathy. Indifferent to mortality and consequences alike, her legacy thrives through glacial efficiency in exterminating threats and an absolute void of emotional ties, securing her mythic status among her world’s ecclesiastical elite.
