Eléonore "Ellen" Bonnefoi, born into nobility, was educated by Bruno de Médicis before becoming tutor to his son, Farma, prior to Farma's reincarnation. She possesses exceptional intellect, having passed the first-grade pharmacist exam at fifteen. Ellen has long silver hair, blue eyes, and severe myopia requiring red glasses, which she frequently misplaces. Her typical attire consists of light blue dresses, white stockings, and black shoes; later, she adopts a modern white nurse uniform while working at the pharmacy. Initially apprehensive of Farma's divine abilities post-reincarnation, particularly his lack of shadow and unconventional powers, Ellen gradually adapted. She transitioned from solely being Farma's tutor to an active collaborator in his pharmaceutical work. Her professional role expanded significantly when she joined the operations of his pharmacy, applying her expertise in compounding medicines and diagnosing illnesses. Ellen overcame an initial dependency on Farma's divine powers. During an outbreak in Marseirre, she was entrusted with independent ship inspections for contagion, demonstrating growing competence and confidence without supernatural aid, highlighting her adaptability and commitment to public health. She can use positive water divine arts to create and manipulate water for medicinal purposes. Her pharmacological skills enable her to formulate effective treatments, though initially less advanced than Farma's scientific methods. A logical and kind personality drives her dedication to alleviating suffering, embodied in her personal ethos: "I won't let anybody suffer when I have the means to help them." Ellen shares a respectful and supportive dynamic with Farma, evolving from educator to trusted colleague. She interacts warmly with Farma's younger sister, Blanche de Médicis, offering art lessons that reveal her own appreciation for creative expression. Her medical history includes chronic myopia requiring corrective lenses, plus minor ailments like a sprained finger and a cold, both treated by Farma. During the aftermath of a major crisis involving Farma, she played a pivotal role in coordinating his rescue from structural collapse and managing his subsequent treatment for crush syndrome, applying pharmaceutical knowledge he had documented, underscoring her capability to lead and innovate under pressure. Her birthdate is March 1st. The family name "Bonnefoi" derives from French, meaning "Good faith."
