Lukić is a faculty member at Luna Nova Magical Academy, where she serves as the instructor for Fundamentals of Magic Pharmaceutics, Fundamental Alchemy, and Magic Law. She is often referred to as the Occult Teacher or the Professor of the Occult, a title earned through her deep fascination with superstitions, curses, eschatology, and other esoteric subjects. Among the teaching staff, she is the oldest and one of the most eccentric, known for speaking in an unsettling manner and expressing genuine delight in grotesque or macabre phenomena. Her personality is characterized by a strange curiosity and a love for potions and dark knowledge, which she conveys to her students through her unique instructional style. Though her primary role is that of a knowledgeable but eccentric background figure, her lessons contribute to the academic atmosphere of the school, and she occasionally interacts with students such as Akko Kagari, whose earnestness she appears to regard with a mix of amusement and interest. Her motivations seem rooted in a passion for the occult and medicinal magic, rather than any central narrative arc, and she undergoes no major personal development over the course of the story. Her notable abilities lie in her extensive expertise in potion-making, alchemy, and magical law, making her a resource for the more arcane aspects of magic at Luna Nova.
