After many years since the last battle, Mars, the god of war, resurrect and wants to dominate earth again. The new generation of saint soldiers join together to fight against newly emerged dark forces.

Ever since the Age of the Gods, whenever evil draws near, a Saint will appear. Wielding the arms called a Cross, they battle to protect the goddess Athena who watches over the Earth. Amongst their number was the Bronze Pegasus Saint Seiya and his compatriots whose battles are legendary. Since then, much time has passed. Now, the revival of Mars, the god of war, draws near, and it is time for a new Saint to step into the breach.—AniDB

Saints are champions of hope who have always appeared since the Age of Myth whenever evil threatens the world. They would clad themselves in armor called Cloths, and fight to protect Athena, the goddess who rules the world's surface. Seiya the Pegasus Saint has saved Athena many times, and while he and his friends are Bronze Saints, which is the lowest rank, their battles have been passed down as legend.—Crunchyroll
