Yoshimori continues to begrudge his older brother, due to his advanced techniques. Masamori finds a birdlike shikigami without a seal sent by an unknown spy. Yoshimori confronts Masamori about the reason for watching him from afar. Yoshimori then tells Masamori that he wants to put a seal on the site, however the latter warns the former that it might trigger a disaster if done recklessly. Masamori departs afterwards, and he summons Kurohime, his demon koi, to search for anomalies, sending a dark aura around the site. The next day, Masamori says to Shigemori that Yoshimori has much more potential as a kekkaishi than he does. The family says farewell to Masamori as he takes his leave. Yoshimori asks Masamori to go bury Koya's fur on his home mountain as a favor. Yoshimori promises to himself that he will surpass Masamori and put a seal on the site someday.
