The Aquila Silver Cloth is the cloth of the Saint Marin in Saint Seiya, Saint Seiya: Episode G, and Saint Seiya: Next Dimension, and by an unknown Saint in Saint Seiya: The Lost Canvas. It is of the second class of the cloths that Athena’s Saints wield, the Silver Cloths.
The Aquila constellation can represent the Eagle who took Ganymede to Mount Olympus. It is said that the Eagle was the form Zeus took when abducting the boy, to make him their water bearer.
Marin trained to be a Saint in Sanctuary by an unknown master. The cloth was likely kept in Sanctuary until a Saint worthy of wearing it was found. Like all Female Saints, she must wear a mask when around men. Marin first appeared in volume 1 of the manga, as the one who was training Seiya. After Seiya leaves Sanctuary, Marin is eventually sent, with several Silver Saintsto take Seiya and his fellow Bronze Saints out, but betrays her allies for Seiya. During this period, she manages to defeat Hound Asterion after being severely injured. During the fight with Sanctuary, she even makes it to the top of Star Hill, something difficult even for Gold Saints. She tells of the true Pope’s death, and then helps Seiya through the poisoned roses by letting him wear her own mask. During the Hades Arc, she locates Seiya’s sister, Seika, and defends her when Thanatos tries to kill her.
The Cloth was seen briefly at a gathering of Saints in Saint Seiya: The Lost Canvas, but has only rarely been seen since.
During Next Dimension, Marin is revealed to still be in Sanctuary, as she attempts to protect Seiya from the Angel Touma. She offers to protect Seiya with Shaina so Hyoga can join Athena. It seems, through the memories of Touma, that Marin might be his sister, meaning he was taken from his family to The Realm of Heaven. Her cloth appears to have been repaired (likely self repaired) since the damage it took in the Hades Arc.
