Chartreux Westia, princess of the Principality of West and scion of Dahlia Academy’s White Cats House, possesses a striking presence marked by short white hair swept across her left eye, luminous golden-brown eyes, and a statuesque frame often accentuated by a feline-eared tiara. Over time, her hair cascades to mid-back length, mirroring her evolving journey.

Bound by a childhood bond to Juliet Persia, who embraced her as an equal despite her royal lineage, Chartreux harbors fervent protectiveness and unspoken affection for Juliet. This devotion manifests in a covert archive of photographs and vigilant surveillance of Juliet’s interactions with Romio Inuzuka—even planting a recorder in his quarters. Initially opposing Romio as a rival for Juliet’s heart, she begrudgingly admires his unwavering loyalty, forging an alliance during pivotal trials and ultimately honoring their union at their wedding.

Her rapport with Scott Fold crackles with playful antagonism, fueled by his overtures toward Juliet, though subtle undercurrents of affection surface when his praise draws blushes. Post-graduation, their dynamic endures, with Chartreux dubbing him her “dog” amid lingering camaraderie. Duty-bound yet detached, she navigates a cordial but reserved relationship with her observant mother, Queen Westia, balancing regal obligations with quiet introspection.

Once a meddling adversary, Chartreux’s arc culminates in graceful acceptance of Juliet and Romio’s love, reflecting her maturation from possessive devotion to a deeper comprehension of loyalty’s selfless dimensions.
