Sengoku Otome: Momoiro Paradox (2011)

Yoshino Hide is an average student who has to brush up on her history knowledge for a test in order to avoid summer classes.

As she goes to a shrine to pray for her success, she spots a woman performing a strange ritual inside the shrine. When she is spotted, she clumsily stumbles towards the woman and they both disappear.

When Hideyoshi comes to, she finds herself in a forest and discovers a blazing village, where a warrior resembling her friend Akemi is fighting against some vandals before a mysterious woman saves her.

Now, Hideyoshi is stuck in the Feudal Era, where women prevail.
