The young warriors who protect the goddess Athena are known as the Knights of the Zodiac. One young orphan, Seiya, is destined to become the Pegasus Knight. Athena has been born into this world, but this time under a dark prophecy that she will lose the war against Poseidon and Hades, and lead mankind to ruin. Seiya stands up against the prophecy, willing to protect her at all cost. But now a god-killer arrow has struck her heart. To save her life, Seiya must ascend Sanctuary and defeat twelve legendary Gold Knights - and he only has twelve hours to do it. Will he make it? And what will happen to the dark prophecy if he succeeds?
Time is running out! Only five hours remain before the god-killer arrow lodged in Athena's chest will kill the goddess. The powerful Grand Master is the only one who can save her life, but to even reach the Grand Master's chambers, Seiya and his fellow Bronze Knights must ascend Sanctuary and pass through all Twelve Houses, each temple guarded by a Gold Knight. Not everyone will complete the journey and reach the summit of Sanctuary where a shocking surprise awaits.
