Chise Hatori, a Japanese teenager born with the Sight—the ability to perceive supernatural entities—is a Sleigh Beggy, a rare magus who involuntarily absorbs immense magical energy from her surroundings, resulting in physical fragility and a shortened lifespan. Her childhood unfolded amid abandonment and tragedy. Her father, also gifted with the Sight, abandoned her to flee with her younger brother, leaving Chise and her mother destitute and tormented by hostile spirits. Overwhelmed, her mother tried to strangle Chise before taking her own life, leaving the girl orphaned and shuttled between indifferent relatives. This trauma fueled severe depression, driving Chise to a suicide attempt and eventual self-sale at a magical auction, where Elias Ainsworth acquired her for five million pounds.

Initially withdrawn and submissive, Chise viewed herself as disposable, resigning to her role as Elias’s apprentice and future bride. Gradually, bonds with mentors like Lindel and Nevin, and her familiar Ruth—a Church Grim bound to her psyche—nurtured emotional resilience, urging her to confront her past and cherish her life. Her journey intertwined with curses: the Dragon’s Curse petrified her left arm into a gnarled limb, while Cartaphilus’s curse replaced her left eye with an immortal one. Initially accelerating her physical decay, these afflictions later fortified her endurance, the immortal eye paradoxically extending her lifespan.

Her magic flourished through necessity. As a Sleigh Beggy, she naturally drew spirits and fairies, channeling magic through song and empathy. She forged a wand from a deceased dragon’s remnants, embodying her duality between life and death. Temporary animal transformations via a mystical pelt augmented her physical prowess, though she wrestled with controlling surges of power, especially after the Dragon’s Curse heightened her senses and stamina.

Relationships anchored her growth. Her dynamic with Elias evolved from transactional to symbiotic, marred by clashes over his secrecy and her quest for independence. Friendships with Alice, Stella, and peers at the magical college tempered her self-sacrificial impulses, offering camaraderie. Ruth’s psychic bond amplified her protective instincts, anchoring her to purpose.

Later, Chise enrolled in a magical college, seeking alternatives to self-destructive solutions and vowing to aid others facing similar battles. This phase showcased her burgeoning confidence and resolve to harmonize duty with self-care. Resolving Cartaphilus’s curse and embracing immortality redirected her focus from survival to carving her identity in the supernatural realm, though questions lingered about her future with Elias.

Her appearance mirrored her inner turmoil. Early practical attire—a green coat, red sweater—gave way to symbols of transformation: the dragon-arm swathed in bandages, the immortal eye gleaming emerald. Artifacts like the Adder Stone necklace and Angelica Barley’s magic-regulating ring signified her ties to Elias and the arcane world.

Childhood isolation bred a fear of thunderstorms, while quiet reflection balanced her occasional fierceness in defending loved ones. Though empathy often spurred recklessness, guidance from Lindel and Nevin taught her to weigh her worth and the ripple effects of her sacrifices.
