Seiya claims victory against Hades, but as a consequence, he is left paralyzed and must rely on a wheelchair for mobility. To regain his strength, Artemis presents a proposition to Seiya: she will heal him, but only if she takes over Sanctuary. Athena, convinced by the offer, agrees to the deal, and the "Knights of the Sky" quickly assume control. The Bronze Saints, including Seiya, must now fight against Zeus' army to win back their territory. However, they face an additional challenge when Hydra Ichi, Unicorn Jabu, and Ophiuchus Shaina ally themselves with Artemis and Apollo.
