Mifi Rotten is a first-year student in the Liberal Arts, or General Studies, department at the Academic City of Zuellni. She originally transferred to Zuellni from the Transportation City of Yoltem, accompanied by her two childhood friends, Naruki Gelni and Mayshen Torinden, with whom she shares a room. Energetic and endlessly curious, Mifi possesses a natural talent for gathering information and a keen eye for interesting stories. She channels this enthusiasm into her part-time job as a reporter for the weekly magazine Weekly Look’n, often approaching her work with an excitable, almost childish glee. Her desire for a scoop sometimes leads her to get too close to ongoing fights or dangerous situations, reflecting her bold and intrepid nature despite her lack of military training. Among her friends, she is known for her hyperactive personality, and she affectionately refers to Naruki as Nakki and Mayshen as Meicchi. Within the story, Mifi serves as a supporting character, providing lighter moments and occasionally documenting key events through her photography and articles. She does not possess any notable combat abilities or Kei techniques, and her role is largely that of a cheerful observer and budding journalist rather than a fighter. Her development remains subtle, with her primary motivation being her passion for uncovering and sharing news within the academic city.
