Battle Girls: Time Paradox
戦国乙女～桃色パラドックス～
Hideyoshino is an ordinary girl who always seems to find trouble wherever she goes. One day, she notices a blue light coming from inside a local shrine and sees a mysterious person performing a magic spell. In a stroke of bad luck, Hideyoshino trips and crashes into the shrine, causing the magic spell to spiral out of control and sending her back in time to the Sengoku Era. But Hideyoshino realizes that everyone in this world is female. She then decides to help Oda Nobunaga find the Crimson Armor, which is said to allow the person wearing it to conquer all of Japan.
