Shikabane Hime: Aka

Synopsis

Mitsuyoshi is stunned after hearing Sumitori's voice through Ouri's cellphone, allowing Minai to defeat Mitsuyoshi. The next day, Minai needs to confiscate to Ouri's cellphone as evidence, but offers to replace his cellphone in return. Shuji, trying to contact Minai but with no response, is kidnapped and later killed by thugs he had offended recently before. This causes Minai to begin reverting to an evil Shikabane driven solely by its regret. She is hunted down by Saki Amase, who wields a giant hammer. When Saki hesitates to kill Minai, Ouri flees and secrets her away into a bar where he works part-time, going out to plan a way for her to escape from the city. Unbeknownst to Ouri, his manager is a Contracted Monk. However, sympathetic to Minai's plight, Minai is told that if she makes a new contract with Ouri as her Contracted Monk, she will be able to return to being a Shikabane Hime, but she chooses to destroy herself instead.
