Eléonore "Ellen" Bonnefoi, a noble of the San Fleuve Empire's Bonnefoi family, possesses long silver hair and blue eyes. She typically wears red glasses but frequently breaks them due to clumsiness. Her attire consists of elegant noble dresses. While working at the Parallel World Pharmacy, she wears a modern white nurse uniform and styles her hair in dual Dutch braids tied into a ponytail. Trained under Bruno de Médicis, Eléonore excelled academically, achieving the rank of First-Class Pharmacist by age 15. She later became the tutor of Bruno's son, Farma de Médicis. Initially frightened upon discovering Farma's supernatural abilities – such as diagnosing illnesses with his "Divine Eye" and his lack of shadow, which she associated with the divine powers of Panactheos, the God of Medicine – she briefly attempted to resign as his tutor. Farma convinced her to stay after demonstrating his benevolent intentions. Over time, she grew accustomed to his powers and became one of his most trusted allies. Her medical history includes dependence on corrective lenses and incidents like a sprained finger and a cold, both treated with Farma's potions and salves. Professionally, she specializes in positive water divine arts and herbal medicine formulation. She is logical, diligent, and deeply compassionate, driven by a principle to prevent suffering whenever possible. Her intelligence is tempered by clumsiness, particularly with her glasses. Eléonore plays a critical role in Farma's endeavors, assisting him in establishing and managing the Parallel World Pharmacy. She aids in combating epidemics, including the Black Death outbreak, helping distribute cures and manage logistics. Following the epidemic's resolution, she is appointed as Farma's teaching assistant at the Imperial Pharmaceutical School. She also participates in high-stakes missions, such as inspecting ships in Marseirre for disease outbreaks, showcasing her growing independence and leadership. Her relationship with Farma evolves from mentor-student dynamics to a partnership of mutual dependence. She becomes privy to his secret as a divine vessel and supports his mission to democratize medicine. She shares a respectful rapport with Bruno de Médicis, who entrusts her with significant responsibilities at the pharmacy. Her development culminates when she rescues Farma from physical peril during a catastrophic event, applying medical knowledge he taught her to treat his crush syndrome injuries. Eléonore transitions from a cautious academic to a proactive healthcare advocate, embodying resilience and adaptability while maintaining her core dedication to pharmaceutical excellence and patient care.
