Hakkenden: Eight Dogs of the East Season 1 Episode 12

Chapter 12: Price Paid

Kohaku returns to her abode, and seemingly "devours" her friend. The next day, she wakes up in a blood-stained room and news about the mysterious death of one of the Zuikou Mansion workers spreads. Shino wakes up, still in his eighteen y/o body, and leaves for the church, where Kohaku escaped to. After Kohaku's explanation of her life story, she starts to grow a pair of rigid wings while Sosuke and Satomi attempt to console her. Shino appears and reveals Murasame as a sword, calling Kohaku an "angel from a picture book," rather than the monster she saw herself as. Shino then falls asleep and once again returns to his child form of a body.
