A pair of twins, named Shirizaki and Sharizaki, who are often in sync with each other. Sharizaki's favored due to the destruction that her fire powers can cause. Sharizaki's a seemingly soft-spoken and naive young girl. While not losing her childish impatience and enthusiasm, she's more thoughtful and feminine, but is almost as irrational and distorted as Shirizaki. Both of them are equally psychotic and take pleasure in humanity's misery.
