Saint Seiya, also known as Knights of the Zodiac, is a Japanese animated series created by Masami Kurumada in 1986. It tells the story of the Bronze Knights who fight to protect the goddess Athena.
Hyôga responds to Saori's call, alerted by imminent danger. But before he can act, Saori is attacked by a divine warrior from Asgard, on the orders of Hilda of Polaris. Athena then travels to Asgard, launching a confrontation. To save humanity, she stops the ice from melting, but only for half a day. During this time, Seiya and his companions face the seven divine warriors of Asgard to recover Odin's sapphires and free Hilda from the Ring of the Nibelungs.
