Where the Peach Trees Bloom
Koharu’s awakening power makes her peach scent irresistible to demons, drawing attacks and eventually Naraku’s attention. Sesshōmaru first protects her out of curiosity and practicality, but as she bonds with Rin and proves her strength, his protection becomes personal. Naraku tests Koharu’s bloodline, discovers her power can strengthen demons but also purify them, and engineers the Blood Trap, where Inuyasha is manipulated into attacking her. Sesshōmaru nearly kills him, revealing to Naraku that Koharu has become Sesshōmaru’s weakness. As Koharu learns the truth about the Peach Maidens and trains to control her abilities, Sesshōmaru slowly shifts from guarding her to trusting her. After she nearly dies protecting Rin, he forges a protective kanzashi from one of his own fangs and gives it to her. Koharu sees it as a beautiful weapon, unaware it is also an ancient yōkai declaration of serious romantic intent. Naraku eventually forces Koharu to surrender by threatening everyone she loves. Sesshōmaru comes for her, but instead of removing her from the battle, he trusts her. Together, they stop Naraku from exploiting the Peach Maiden bloodline. The story ends with Koharu learning the true meaning of the hairpin and choosing to continue walking beside Sesshōmaru.
