The Paris unit splinters the moment their anchor leaves. What emerges isn't a smooth handoff but a genuine power vacuum, where capability doesn't automatically translate to trust. The show builds real friction from that gap, then asks who actually holds a team together when the answer stops being obvious. It's a spiritual sequel that knows better than to repeat what worked before, instead using absence itself as the narrative engine. The mecha fights matter less than watching four different women argue about what leadership even is. By the end, you understand why the original captain was necessary in ways the show never explicitly states.

Set right after the events of Sakura Taisen 3, this three-episode OVA picks up with the Paris Flower Defense Force just as Ichiro Ogami leaves for Japan to take command of the Imperial unit again. Because he never named a successor, the women of the squad fall to arguing over who should become the next captain. While they bicker, a threat that has lasted for centuries rises to endanger Paris. The team must decide whether it can set its disputes aside and fight together, and whether it will pick its own leader or have one imposed on it. Expect mecha action and science fiction adventure centered on a divided ensemble.
