2The series begins with the story of Seiya, the main hero, who is one of Athena's Knights. Seiya, along with the other Bronze Knights, must train hard to earn their Cloths, and take on other challenges as well. Knights of the Zodiac (Saint Seiya) has been a hit in Japan (where it is known as simply Saint Seiya), as well as many European countries including Spain, France, and Italy.

As the Bronze Knights fight their way through the 12 Palaces of the Gold Knights, their strength ebbs...and their enemies' strength increases. Now Hyôga must defeat the relentless Scorpio Knight while his own senses diminish to nothing. Shiryû is left alone against the Capricorn Knight, whose strength can split even Shiryû's invincible Dragon Shield. And shy Shun demands to take on the Pisces Knight, against whom he has a personal vendetta. With the full force of Sanctuary bent on destroying the four exhausted Bronze Knights, Princess Sienna's mission seems impossible. But, as Seiya is about to discover, the Princess brought a secret weapon to the 12 Palaces...something that will upset the balance of power in Sanctuary and reveal a message of hope in the Bronze Knights' darkest hour!
