Fumika Momoshina stands at the forefront of the Actresses, a group of young warriors entrusted with defending humanity against the Vice through advanced mechanical suits called Alice Gears. Her name, combining the characters for "writing" and "praise," and her surname, meaning "encyclopedia," mirror her intellectual nature—a trait reinforced by her signature glasses and ever-present book. Balancing battlefield duties with the glittering demands of idol life, she navigates dual roles with strategic precision. When their manufacturing company teeters on collapse, Fumika pivots from combat to creative problem-solving, spearheading efforts to sustain operations through unorthodox ventures: running a themed café and leading ghost-hunting escapades. Her adaptability shines as she harmonizes teamwork with crisis management. Clad in the Libra armor suit, she switches seamlessly between casual and combat modes, wielding the Hegel Mk3 bazooka and Champolion Mk3 sword alongside missile racks and tactical gear. Interchangeable face plates toggle her demeanor from scholarly calm to battle-ready intensity, embodying her duality. As a mentor, she tailors rigorous training programs for peers like Nodoka Takahata, fostering growth through patience and ingenuity. Her leadership blends disciplined guidance with flashes of humor—blushing at lighthearted teasing or navigating quirky fan service moments—though her focus remains steadfastly on collective goals. Vibrant, futuristic design elements define her visual aesthetic, aligning with the series’ dynamic tone. Her story orbits group triumphs over personal history, emphasizing unity as she and her comrades juggle the demands of war and spectacle, their bonds forging resilience in the face of shared adversity.
