Description
Isabelle Norton is the only daughter of Count Kerbeck, a noble family in the Kingdom of Ridill whose lands are frequently troubled by dragon attacks. She is a beautiful young girl with curled orange hair that falls to her waist, which she often ties with white and black striped hair ties, and she has green eyes. Her standard attire at school includes a white stole worn over her uniform, and she is frequently seen carrying a large feathered fan. Due to her upbringing, she displays the elegance and refinement expected of a high-ranking noble heiress and is often accompanied by her loyal maid and bodyguard, Agatha.

Her personality is multifaceted, shaped by both her noble responsibilities and her personal experiences. Having witnessed the destruction caused by dragon raids throughout her life, she developed a strong sense of honor and duty towards her family's subjects, refusing to flee from danger even when hopeless. At Serendia Academy, she deliberately plays the role of a villainess, publicly bullying Monica Everett to maintain a necessary cover. However, this public persona masks a fundamentally responsible, intelligent, and genuinely kind individual. In private, she is playful and affectionate, dropping the harsh facade to reveal her true nature as a supportive and warm friend. She has a keen sense of duty, impeccable politeness, and a pronounced taste for fashionable romance novels from the capital, a hobby she shares with her maid, Agatha. Her theatrical villainous laugh has become one of her trademarks, and she proudly claims her performance is unmatched at the academy.

Isabelle's primary motivation stems from a deep and abiding admiration for the Silent Witch, the title held by Monica Everett. Three months before the story begins, a calamitous Black Dragon incident struck the Kerbeck territory, a crisis that Monica resolved almost single-handedly. Awestruck by Monica's power and bravery, Isabelle and her family became her devoted fans. When the opportunity arose to assist Monica in a covert mission, Isabelle agreed without hesitation, driven by her admiration and a desire to protect the hero she idolizes.

Her role in the story is that of a collaborator and a secret protector. She is one of the very few people aware of Monica Everett's true identity as the legendary Silent Witch. To help Monica infiltrate Serendia Academy under a false identity, the Norton family adopted her fictitiously, making Isabelle her fake younger sister. Isabelle also enrolls at the academy, one year behind Monica, to act as her on-the-ground ally. To shield Monica from social prejudice and harassment from other nobles who look down on commoners, Isabelle pretends to bully her in public, claiming Monica as her possession to deter others. She tolerates the resulting negative reputation without complaint to ensure the mission's success and Monica's safety.

Key relationships define her actions and development. Her most significant relationship is with Monica Everett. While she begins as an ardent fan of the legendary Silent Witch, her admiration deepens into genuine friendship as she comes to understand and accept Monica's true, anxiety-ridden personality. She calls Monica her "big sister" in private and fiercely supports her, protecting her from social threats and offering a safe space away from the pressures of her mission. Her bond with her maid, Agatha, is also notable; they are trusted friends and confidantes who often gush over Monica together and share a love for romance novels. Her development sees her transition from a distant admirer of a legendary figure to a proactive and indispensable ally who understands and accepts the real person behind the myth, providing unwavering support despite the personal cost to her own reputation.

Isabelle Norton possesses several notable abilities that make her a crucial asset. She is a master negotiator, capable of dealing on equal footing with the academy's headmaster and other powerful nobles, applying immense social pressure to protect Monica from malice. Her charisma naturally commands loyalty from her peers. She is highly analytical and discerning, skills she uses to assess dangerous situations. Realizing she knew nothing about Monica's academic studies in magic, she also took the initiative to learn basic elemental magic. Finally, her perfected skill is her theatrical "villainess performance," a role she practices daily to maintain their cover and protect Monica from harm.
