The Luminous Witches exist in the margins of a war nobody can win. They sing and dance while cities burn, and the show never flinches from how hollow that sounds until you realize their job is to make that hollowness bearable. The aerial displays set to original music are genuinely breathtaking, but what hits is watching girls who could be soldiers choose to be something gentler instead, even when gentleness feels like surrender. The OST doesn't just underscore the performances, it becomes the argument for why morale is a weapon the front lines can't provide.

An alien invasion by the Neuroi is dragging on, and missiles alone won't win the war. That's where Ginny and the Luminous Witches come in. As performers for the League of Nations Air Force, they skip the front lines to do something just as important: lift the spirits of civilians driven from their homes. Their weapon is music and dance, paired with aerial displays unlike anything audiences have seen. The idea begins with Grace Maitland Steward, a retired witch still in the army, whose proposal to boost morale through music is dismissed by her superiors. To prove its worth, she recruits singing witches Aila and Eleonore to help form a music squadron. Among the recruits is 14-year-old Virginia Robertson, who has no military background but shows an ability too notable to overlook.
