Camus Peligor studied at the El-Melloi Classroom in the 1990s under Kayneth El-Melloi Archibald until a griffin attack—potentially orchestrated by classmate Amleth Wotan—shattered her Magic Circuits. Scarred physically and magically incapacitated, she was expelled from the Clock Tower.

Years later, as CEO of Peligor Corp, Camus embraced an androgynous aesthetic, dressing in sharp masculine attire and adopting the pronoun "boku." Her once-timid demeanor hardened into calculated confidence, though bitterness toward Amleth lingered beneath her composed facade. She spoke in a low, raspy tone, occasionally punctuating sentences with nostalgic French phrases like "au revoir."

Her sole memento, a camera from her father, anchored her family’s Shell Projection magecraft. Using it, she ensnared former classmates in an illusory replica of their Clock Tower days, freezing them in an observed, projected memoryscape. Touko Aozaki’s puppet bodies sustained the illusion indefinitely, allowing Camus to preserve her idealized past. The scheme’s collapse drained her remaining Circuits, severing her from magecraft entirely.

Though she abandoned the supernatural world, fragments of her former self endured: the treasured camera, fleeting French utterances, and unresolved yearning for the camaraderie she lost. Her actions laid bare a rift between her fractured present and the fleeting joy of her youth, a chasm she sought to bridge through illusion.
