This is "Holy Hierarchy Academy," the world's best girls' high school that trains future stars. Here, the top dog students have all the control, and they possess a unique beverage: the Hierar Milk, extracted from the mythical bovine, the Hierar Beef. One swig from these divine drops bestows enough radiance and go-getter energy that nothing but the position of top dog will satisfy.<br>
