Ran to Aoi

Turbulent times are coming to an end, but women must continue fighting. Ran Hattori fled her wedding to live as a shinobi rather than as a wife. Meanwhile, Takechiyo, who will be known as Iemitsu Tokugawa, is shunned by his mother, and someone is plotting to assassinate him. Within Edo Castle, amid a fierce battle for succession, the two—never meant to meet—begin to develop feelings that go beyond those of master and servant.
