Saint Seiya: Next Dimension - The Myth of Hades

In Greek mythology, Athena, the daughter of Zeus, was born in full armor. By birthright the goddess of battle, she did not believe in conquest, and only fought defensive wars. Her battles with bloodthirsty gods and giants shook the very earth and seemed to last forever. On the battlefield, there were a group of youths that always surrounded and protected the goddess: the Knights of Athena! Flash forward to modern-day Greece: two Japanese tourists are shocked to see a mansized meteorite crash to the earth before them. It turns out to be young Seiya. Seiya must train harder than ever if he is to survive his match with the brutal Cassios! Whoever wins will receive the greatest prize known to man: the incredibly powerful Pegasus Cloth!
