Five Mirrors of Hope

The Five Mirrors of Hope are medium-sized mirrors that have six black tomoe on each side of them: one at the top, two on the bottom left and right sides, two on the upper left and right sides, and one in the center. They have five different colors each: red, blue, yellow, green, and black. They are said to be the only way to stop Genshō Ryūdōin from reanimating the Spirit Beast.
