Tokimori Hazama (間時守, Hazama Tokimori) was the first Kekkaishi and the founder of the Hazama-Ryu Kekkaijutsu. He served as the first guardian of Karasumori, a tradition that has been continued for centuries. Though he had no related heirs to continue his work, Hazama passed down his teachings to other ability users, and is therefore considered the ancestor of all Kekkaishi who were trained in his style.
