Kekkaishi episode 11 English Subbed Episode Description: Yoshimori encounters and captures three minor ayakashi, them being Honetaro, Uhosuke, and Nagao. However, their leader Koya, who is a demon dog, shows up in anger. It is revealed that Koya had been a former companion of Madarao, Yoshimori's demon dog. It was a half millennium ago that Madarao and Koya were chased away by the humans from their mountainous habitat. Madarao had died of starvation, while Koya had been killed in the hands of the humans, resulting in their separation as friends. As Koya transforms into his true form, Madarao convinces Yoshimori to release his collared seal in order to transform into his true form as well. After Yoshimori carries the three followers out of the way, Tokine is to keep an eye on them, while Madarao and Koya begin to battle.
