UG☆Ultimate Girls EP1 - Ultimate Battle #1

While looking for a better vantage point for viewing the monster attacking Tokyo, Silk, Vivienne, and Tsubomi get crushed by the giant hero UFO-Man as he comes to save the day. He resurrects them, but at the cost of being unable to fight the monsters himself. He gives Silk the power to transform into a giant heroine, but her costume only lasts a few minutes before beginning to disappear. Silk saves the day by defeating her first monster.
