Giji Tenshi (疑似天使, False Angel), otherwise known as Pseudo Tenshi and Yakubyōgami (疫病神, Angel of Death) respectively, were a collective group of experimental Souls created by Kagura as part of the latter's racial research. Due to the nature of Kagura's experiments, many of the Yakubyōami became corrupted, their appearances and personalities having become distorted to a shadow of their former selves. Fortunately, a few of the Yakubyōami managed to subvert the corruption and survive mentally and physically intact.
