Rachel Benning begins as a vibrant, socially entrenched teenager, her world revolving around fashion, beauty, and the relentless pursuit of social clout. This glittering existence shatters with her sudden death and reanimation, hurling her into a fractured reality where she navigates decaying human connections and burgeoning supernatural obligations. Her unraveling sanity strains under eroding friendships—poisoned by romantic rivalries—and a widening rift with her boyfriend, amplifying her inner chaos.

Reborn into nocturnal warfare against grotesque entities, she fights with feral intensity, outpacing allies in both brutality and skill. Initially, she clutches at remnants of her old life—obsessively maintained nails, meticulously styled outfits—as fleeting comforts. But these habits wither as isolation severs her from humanity.

Centuries later, she emerges transformed. Gone are the trappings of vanity; she now dovers utilitarian garb, her mind sharpened by technical manuals and blueprints. Intellectual curiosity fuels her engineering feats, culminating in sleek war machines—among them a towering, stylish robot blending form and function.

Her past reveals a rebellious Osaka chapter marked by visual kei’s flamboyance, where she paraded in ever-changing avant-garde ensembles. This penchant for reinvention echoes in her later metamorphoses.

In this distant era, she resides with fellow outcasts, operating as a nocturnal bounty hunter. The once-social butterfly has hardened into a resourceful survivor, yet her loyalty to the group remains unshaken—a testament to her prioritization of collective endurance over faded obsessions with image.
