But even though she underhandedly gains knowledge of his secrets by doing so, little does she expect that her actions will unleash the Kira Master’s wrath and send Yoite flying out of control! As the ninja of Banten look on, each with a different purpose at heart, their paths will diverge under the pressure of two forbidden arts coming head-to-head…
