Mahou Shoujo Tokushusen Asuka

Asuka Otorii survived a war in which magically empowered girls saved humanity from monstrous invaders. Three years later, she wants the unremarkable life of a high-school student, but memories of battle and lost comrades make peace difficult to inhabit.

When violence threatens the people around her, Asuka must use the powers she hoped to leave behind. Reunited with other survivors, she faces terrorism and military operations in a world where magic remains a weapon and victory never truly ended the fighting.
