The Otoori clan was one of the two old families, who lived on Hatsumi Island. The Otoori clan posessed one of the two cocoons, but lost it. When Karasawa Shirou was captured by the Otoori clan, the fate of the clan was sealed. When Ende executed Karasawa Shirou's escape plan, Ende infected most of the Otoori clan's people and transformed them into Kanshu. After seven years, these Kanshu are now Kamogari. As a counter-measure to the Coffin Princess Julie, the Otoori clan posessed the Holy Body.
