Shortly after the previous events, Saori Kido (Athena) suffers an attack thanks to the last silver knight who was still alive, which ended up leaving his life on the verge of death. To save Athena, who was hit in the heart by a golden arrow, Seiya and the other Bronze Saints need to cross the Twelve Houses of the Zodiac and bring the Grand Master so that he can remove the arrow before the twelve hours end. And for that, the five will have to bravely explore each of the houses and challenge all the Gold Saints to reach their goal, even if it costs their own lives.
