Kekkaishi - Season 1 Episode 45 Kokubourou's Human Sacrifice
Overview: Tokine manages to infiltrate Kokubouro by following Shion. Masamori frees Atora and destroys Sakon with ease. As his night troops recuperate, he discovers that both Yoshimori and Sen are missing and that they are both currently in Kokubouro. Yoshimori is restrained by Shion's webs, but his aura repels anything else Shion tries to do to him. Byaku arrives and tries to plant a bug inside Yoshimori, but, he too, was repelled by Yoshimori's aura. Masamori gathers any movable night troops to head to Kokubouro. Matsudo Heisuke, along with his companion Kagami, busts through the ceiling, scares Shion away, and frees Yoshimori under agreement in which Yoshimori must not touch this "white" target. Heisuke and Kagami destroy the castle buildings while Yoshimori heads off to find Kaguro.
