Knowing of Aria's whereabouts, the Bronze Saints set off to invade the final ruins, followed by Ophiuchus Shaina, who joins them. Before parting, Shaina reveals to Kōga the secret of his origin, as well as Aria's. Inside the ruins, the Bronze Saints face the threat of powerful Silver Saints, while Kōga engages Orion Eden to free Aria. Shaina takes Aria and with her help, they are able to vanquish Mars' dominion over the area.
