Leader of "Angel". Shizuka leads the members of Angel against the mysterious Kodai-Jinki, and she is also the mother of Aoba. Shizuka ordered Aoba's kidnapping because she believed Aoba's cognate abilities would benefit Angel. Her true intentions however, was to turn Aoba into a killing machine that would follow her and Kokushou in destroying the world. The reasons behind this weren't explained in the anime, but was elaborated in detail in the on-going manga series, specifically in volume 7 of Jinki:Extend. After the events in the Venezuela arc, the trauma dealt to her during the conflict turned her into a human vegetable, and her life was eventually used to create the clone, Shiva.
