It opens with a curtain going up, and that is the whole thesis: this thing wants to be a show before it wants to be a war movie. The Imperial Theater cover story is played straight, so the Flower Division rehearses blocking in the afternoon and drops into steam-powered Koubu at night, and the animation is lavish enough that Taisho-era Tokyo actually feels lived in rather than painted on. Ogami being off in Paris is the sneaky masterstroke, because it hands the film to Ratchet Altair, the outsider nobody in the troupe wants, and forces Sakura and the others to earn her instead of the reverse. That is also exactly why it splits rooms. Walk in cold and you get a gorgeous, baffling 90 minutes with a cast that assumes you already know why Sumire's attitude matters. Walk in having played and watched the rest, and Ratchet finally taking her place on that stage lands like a debut you personally waited for.
Sakura inherits her father's burden: protecting Tokyo from supernatural threats using a massive combat mecha. What she doesn't expect is that her real job title includes stage performer. By day she's a theater actress in an elaborate cover operation, by night she's piloting mechanical armor against otherworldly forces trying to breach reality itself. The twist is that both roles matter equally. The stage presence and charisma she develops as an entertainer directly feeds into her ability to lead her squadron and inspire hope in civilians. As the Black Sanctum Council makes its move against the city, Sakura must balance rehearsals with combat training, romantic entanglements with strategic planning, and her own doubts about whether she's truly ready to carry on her family's legacy. The action sequences are kinetic and colorful, but the movie's heart lies in watching Sakura discover that being a hero means more than just winning battles. It means connecting with people, whether you're on stage under spotlights or in a cockpit facing down demonic adversaries. Drama and spectacle intertwine as the stakes keep rising.
