Papillon Rose

We find the girls in town a year later going about their lives without any memories of their past exploits or ability to transform. Tsubomi is approached by Rama, the cat, who, at first, she does not understand. But the Earth, specifically the town of Akiba, is under attack by a trio of powerful alien women along with their minions. The explosions around her restore her memories and she reassembles the rest of the Papillon team to defend the town, eventually winning over the enemy with their charms as well as their magical powers.
