In her attempt to save Kimiya Hachioji from Nouotoko, the parasitic Ayakashi possessing him, Tokine Yukimura agrees to accompany them to an abandoned warehouse. There, Nouotoko reveals that he is working for an Ayakashi group known as Kokuboro, who are buying and selling information about Karasumori and the Kekkaishi who guard the site. After he insults Tokine by calling her the weakest Kekkaishi, she brutally attacks Nouotoko, showing him that she is also the least merciful Kekkaishi. Tokine forces him to reveal all he knows about Kokuboro: that it is based in a black castle, that they are unusually organized for any Ayakashi group, and that they seem to think as humans do in that they will do anything to reach their goals.
