Platalissa Bonaire, a Finnish girl born March 3 (Pisces), enrolled at Camelot Academy’s Japanese branch at age 11 after failing the main English branch’s entrance exam. This failure strained her relationship with her admired older sister, Sfida Bonaire, exacerbated by parental pressure conditioning her return home on outperforming Sfida in the Camelot Cup. Initially cheerful and gentle, Platalissa adopted a cold, distant, and competitive demeanor, treating classmates as rivals to defeat. Her isolation manifested through serious expressions and self-contained behavior, though she retained deep care for Sfida and desire for family approval. A cross-adorned choker from her mother symbolized tension, as Sfida resented not receiving it. During the Camelot Cup, unable to surpass Sfida’s score, peer support from figures like Ice Carmine fostered reconciliation with classmates and her sister. This resolution eased her emotional burden, restoring her innate kindness and cheerfulness. Later, classmate Liebel Ringvald complimented her appearance during vulnerability, sparking romantic feelings. Despite learning Liebel might harbor feelings for teacher Aria Sayfort, Platalissa trusted her emotions and supported him; they married years later. Golf served as both pressure and achievement, with key skills including a 210-yard average driver distance, 2.3 putts per round, and a personal best of -4. Post-reconciliation, her gameplay improved, culminating in a Kurumi Country Jr. Cup win against Yumiko Koizumi. Flashbacks later indicated she ceased competitive golf. Among peers, Wanglian Li proved notably easy to converse with. Though some perceived her as Italian due to her name, her Finnish nationality remained confirmed.
