Moe Isurugi is a 14-year-old Valkyrie cadet stationed at the Japan Air Self-Defense Force's Tateyama Base. Official records list her birthday as June 16, though personal documents note an alternative date of November 14, 2010. She stands 158 cm tall with blood type O. Recognized as a prodigy, Moe excels in both theoretical studies and practical piloting of Heroic Aircraft, operating a P-51D Mustang. She frequently partners with fellow cadet Kurumi Suzuhara, serving as a stabilizing force against Kurumi’s recklessness and adopting a supportive role during joint operations. Moe participated in the high-stakes Fuji Pillar assault commanded by Toshizo Okita. When her squadron faced an unexpected counterattack, Sonoka Watarai’s intervention rescued her from imminent danger, enabling Moe and Kurumi to return safely.
