Due to his natural ability to subdue Ayakashi without the use of sealing, Tokimori Hazama was able to collect a large number of them during his years as a Kekkaishi. Though he initially only kept them as pets and occasional helpers, some would be assigned to assist future Kekkaishi clans in protecting the land of Karasumori. Others have apparently remained in Hazama's service, with a few ending up as playmates for his son Chushinmaru Karasumori.
