An anime-original spin-off/sequel based on the Saint Seiya series: The god of war and guardian of his namesake planet, Mars, was once sealed away by Seiya, but time has passed and his revival is at hand. Meanwhile, Saori Kido is raising the boy Kouga, whose life Seiya saved, and he's been training every day to become a Saint in order to prepare for the coming crisis. Unaware of his destiny, when Kouga awakens to the power of his Cosmo hidden inside him, the curtain will rise upon the legend of a new Saint.

The Summer of "Anu": In a summer once every five years, demons in the mysterious Tower of Druaga lose their powers due to the magic spell cast by a god named "Anu". King Gilgamesh, ruler of the kingdom Uruk, uses the appearance of demons as an excuse to invade the tower and find out the construct's secrets. As 80 years passed, the Uruk army managed to fight back the demons and built a fortress city and safe haven on the very first floor of Druaga—Metz Kier. Thus begins the story of a warrior named Jil, who, finding companions along the way, embarks on a quest for the fabled Blue Crystal Rod, a powerful artifact rumored to be in the highest floor of Druaga. However, other competitors, including the kingdom of Uruk itself, want the treasure, all for their own reasons.
