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 colours- red, blue, yellow, green, and black. They are said to be the only way to stop Genshō Ryūdōin from reanimating the Spirit Beast.
