Wearing holy armor called "Cloth", they have protected the goddess that rules over this world, Athena.

Meanwhile, a boy whose life was saved by Seiya years ago, is being raised by Athena and Saori to become a Saint and fight in the coming battle. When the power within him awakens, a new legend of the Saints begins!
