Sizilien von Klode, also known as Sicily von Claude, is the third daughter and fourth child of House Claude. Her father serves in the Earlshide Kingdom's Finance Bureau, while her mother, Irene von Claude, shares a strong resemblance with her. She has two older sisters, Cecilia and Sylvia, serving in the Royal Magic Division, and an older brother, Royce, the family's heir presumptive. Raised in nobility, she knew other noble children like Maria von Messina and Prince August von Earlshide from a young age. Her status attracted frequent marriage proposals, yet she remained uninterested in suitors before meeting Shin Wolford. She possesses waist-length light blue hair with bangs framing her forehead and distinct chest-length strands at the front. Her eyes are a petrol or blue-green hue. Consistently described as beautiful and cute, her figure draws significant male attention, contributing to her popularity among peers. Her personality is timid, soft-spoken, thoughtful, polite, and shy. She prioritizes others' well-being and strives for social harmony. Despite this gentle demeanor, she exhibits sudden outbursts under intense embarrassment or stress. A strong sense of justice guides her; she strictly adheres to Earlshide Kingdom's laws and refuses to misuse her noble status. This principle led her to reject Kurt's aggressive marriage proposal, resulting in his expulsion from the Magic Academy after he leveraged family influence. Others note her kindness, like Melida Bowen, though she initially felt guilt over potentially exploiting Shin's kindness for protection. Her relationship with Shin began when he rescued her and Maria von Messina from demon hunters. This sparked immediate admiration, evolving into deep romantic feelings. Their bond progressed from mutual shyness to a formal engagement and marriage proposal. Shin's tutoring significantly enhanced her magical abilities, and shared experiences at the Advanced Magic Academy deepened their connection. She becomes notably protective and occasionally aggressive toward Shin when other girls act familiarly, showcasing a possessive streak rooted in jealousy. She also displays intense anger if Shin is threatened or harmed. The engagement received approval from both families, with her parents prioritizing her happiness over politics. Academically, she ranks 4th in the S-Class of the Advanced Magic Academy's first year and belongs to the Ultimate Magic Research Society. Initially specializing in healing, her proficiency earned her the title of "Saint" among citizens of the Earlshide Kingdom and beyond. Under Shin's guidance, her healing abilities became second only to his. She also demonstrates exceptional skill in search magic, noted as the best among her peers. Beyond healing, she developed formidable barrier magic capable of dual-layered defenses and offensive power strong enough to obliterate demons. Training under Shin and Merlin Wolford honed these combat skills, enabling effective contributions against demonic threats. Her character development shows a shift from passivity to assertiveness, particularly in defending her relationship with Shin and confronting adversaries. She adopts a proactive role in personal and combat scenarios, balancing inherent kindness with newfound resilience. Actions like protecting civilians in the Swedes Kingdom solidified her "Holy Maiden" reputation, reflecting growing confidence and the impact of experiences alongside Shin and allies.
