Battle Girls: Time Paradox - S01

Yoshino Hide is an ordinary girl who always seems to find trouble wherever she goes. One day, Yoshino visits a local shrine to pray so she can pass her upcoming test. But Yoshino sees a blue light coming from inside the shrine and looks in to find a mysterious person casting a magic spell. In a stroke of bad luck, Yoshino trips on a small bell and crashes into the shrine, prompting the stranger to catch her. When Yoshino is caught, the magic spell spirals out of control and sends Yoshino back in time to the Sengoku Era. Yoshino then meets Akechi Mitsuhide and Oda Nobunaga. But unlike what really happened during that era, Hideyoshino realizes that everyone in the world is female. She then decides to help Oda Nobunaga find the Crimson Armor, which is said to let the person wearing it conquer all of Japan.
