Yoshino Hide is a normal girl who always manages to get herself into trouble. Yoshino goes to a nearby temple to pray one day in order to pass her forthcoming test. Yoshino, on the other hand, notices a blue light emanating from within the Shrine and enters to see a mystery person performing a magic ritual. Yoshino stumbles on a little bell and smashes into the shrine, forcing the stranger to apprehend her. When Yoshino is apprehended, the magical ritual goes out of control, sending him back in time to the Sengoku Era. Yoshino is later met by Akechi Mitsuhide and Oda Nobunaga. However, unlike what actually occurred during the times, Hideyoshino thinks that everyone in the world is female. She then makes a decision.
