Sizilien von Claude, recognized as Sicily von Claude, is the third daughter of the Viscount Claude family, raised within the noble circles of Earlshide Kingdom. Her early life intertwined with figures like Prince August von Earlshide and Maria von Messina, fostering connections that shaped her diplomatic grace. She possesses striking waist-length blue hair, blue-green eyes, and an elegant figure mirroring her mother, Irene von Claude. Though initially timid and soft-spoken, prioritizing others’ welfare and adhering strictly to laws without leveraging her status, Sizilien reveals a steely assertiveness when provoked—particularly in matters involving her fiancé, Shin Wolford. Their engagement ignites a protective fervor, prompting sharp reactions to those encroaching on their bond. Her bond with Shin began when he rescued her and Maria from harassment, sparking admiration that evolved into a devoted partnership. Overcoming initial shyness, she grows proactive in their relationship, occasionally employing guilt to secure Shin’s aid—a tactic she later regrets. A prodigious student at the Advanced Magic Academy, Sizilien ranks fourth in the S-Class and joins the Ultimate Magic Research Society. Initially mastering healing magic to earn the title "Saint," her training under Shin and Merlin Wolford expands her prowess to offensive spells, demon-slaying combat, and a unique two-layered magic barrier. Her search magic surpasses peers, cementing her reputation. Challenging noble societal norms, she confronts threats targeting her ties to Shin, displaying combat resilience when his safety is jeopardized. Her family’s shared trait of intimidating assertiveness emerges when angered. Born on March 12, Sizilien garners admiration from male peers, yet Shin captivates her as her first true romantic interest due to his unorthodox nature. Her humanitarian efforts during the Swedes Kingdom crisis earn her the "Holy Maiden" title, enhancing her revered public stature.
