Kaguro (火黒) was one of the strongest Ayakashi in Kokuboro (and therefore one of the few able to resist Byaku's control worms). Though he does not participate in the leaders' meetings, Kaguro has a great deal of influence among them, and is often sent to Karasumori in human skin to observe attacks on the Kekkaishi. Kaguro is eventually defeated by Yoshimori.
