S1·E44 Karasumori's War

Yoshimori, Tokine, and Masamori and his night troops are stationed in Karasumori waiting for the enemies approaching. The night troops and the Kekkaishi easily fend off a horde of low-level ayakashi. Meanwhile, Yoshimori, still having his mind set on avenging Gen, leaves the battlefield in search of Kaguro. Yoshimori finds Kaguro, but it turns out that it is actually Shion wearing the same human skin Kaguro wears in disguise. Yoshimori allows himself to be taken by Shion to go to Kokubouro in order to get to Kaguro. Unfortunately, Sen who was tailing Yoshimori gets caught as well. Back at the site of Karasumori, Masamori faces off against Sakon. However, Sakon takes Atora as a hostage to complicate matters.
