Secret moves

 * Ryūsei Ken (流星拳, lit. Meteor Punch): Marin's main attack. She hits with her fist hundreds times in one second to generate a punch burst, much like a meteor shower. This is the technique she taught Seiya, but because she was not the Pegasus Saint, her version was not called "Pegasus Ryu Sei Ken."
 * Eagle Toe Flash (イーグルトゥフラッシュ, Īguru Tu Furasshu): She used this attack to beat Hound Asterion, and it's like a really hard flying kick.
 * Kūken (空拳, lit. Empty Fist): A non-offensive technique involving the creation of illusions. It was used to simulate a mortal blow on Seiya, to prevent Lizard Misty from killing him.

Sanctuary Arc
Marin is a Japanese female Silver Saint who resides in the Athena Sanctuary, in Greece. She was separated from her little brother and she has been looking for him. When Seiya went to the same place to train as a Saint, as Seiya was Japanese too, he was assigned to Marin, who was a hard trainer, but she would turn Seiya into the Saint he is now. When Seiya became a Bronze Saint, Marin had some rivalry problems with Ophiuchus Shaina, Marin refuses to fight her to save Seiya but he broke Shaina's mask, and Shaina was forced to let him go.

Later, Shaina gets a training match against her, but soon discovers that Shaina is trying to take revenge on her. Marin tries to defend herself, but Shaina proves to be tougher and faster. Marin gets tired quickly and is forced to pullback. Shaina knocks down Marin with her Thunder Claw, and she won't let her to recover, Shaina keeps beating her until Marin was completely stunned, then Shaina decides to use her fists hitting Marin even harder, with every punch Shaina deals a crushing blow after another, Marin is completely overwhelmed, unable to strike back Marin bleeds profusely, but Aiolia quickly interrupts this vicious beating by saving Marin before Shaina finishes her off.

Marin saves Seiya first time
Marin does not take long to recover from her wounds, Shaina only seeks to humiliate Marin that's why Shaina didn't hit her vital points, but it is no less true if Aiolia had not intervened in the end Shaina would have ended up killing Marin.

Marin saves Seiya from Shaina on his first visit to the Sanctuary as a bronze saint, Marin interrupts Shaina when she was strangling Seiya, Marin warns him to go to help Hyoga and let him escape by blocking Shaina's path. Shaina had her cloth and could defeat her again but she can't risk being discovered attacking an unarmed Marin outside the Sanctuary.

Traitor
When Gemini Saga, disguised as the Pope, ordered the Silver Saints to attack and kill the traitorous Bronze Saints (the ones who had broken Athena's law about fighting because trivial reasons), Marin was ordered to go too. She went with Lizard Misty, and with Mu's help deceived Misty, making him believe that she had killed Seiya. Misty discovered the truth, and fought with Seiya but was defeated by Seiya.

Marin came back with Hound Asterion and Whale Moses to investigate what happened with Misty, and she was discovered by Asterion's mind reading power as a traitor. She quickly attacked Moses, but with Asterion's help reading Marin's every move before she could attack, Moses defeated her. Then she was tied to a post in the sea as bait to attract Seiya. During the battle with Seiya, Moses said that Marin and Seiya could be siblings due to their similar backgrounds. If so, Seiya can watch his possibly found long lost sister die. Seiya becoming furious at this, gathered more strength and defeated Moses. When Seiya was going to help Marin, Asterion stepped in and knocked out Seiya. During that time, Marin untied herself and intervened to fight Asterion. She cleared her mind of thoughts, meaning Asterion could no longer read her mind. As Asterion used his Million Ghost technique, Marin countered with her Eagle Toe Flash and defeated Asterion without killing him. She told Asterion to go back to sanctuary and send Pope a message. She then disappeared for some time, having left Seiya a message in the sand: "Protect Athena", a secret message which later revealed Saori Kido is the true Athena.

The Truth is Revealed
During the fight with the Gold Saints, when Seiya was heading to Pope's palace and was poisoned by Pisces Aphrodite's Demon Roses along the stair way, Marin appeared to help him. She gave her mask to Seiya to help filter the scent of the roses, but without the mask to protect herself, she fainted. Seiya recovered with the help of Marin's mask and blew away the roses with his Pegasus Ryuu Sei Ken, he didn't want to leave Marin alone and was tempted to look at Marin's true face (for rumor about Marin could be his sister), but Shaina appeared and told Seiya that she will take care of Marin. When Marin recovered, she explained to Shaina that she had gone to Star Hill and she had discovered the real Pope, Shion's corpse, so the truth was revealed. Star Hill is only reserved to the Pope, only one with great power was able to climb to the top of it, so it took a real effort for a Silver Saint like Marin.

Aquila Myth and Constellation
In classical Greek mythology, it was identified as the eagle which carried the thunderbolts of Zeus and was sent by him to carry the shepherd boy Ganymede who he desired to Mount Olympus, where he became the wine-pourer for all the gods. This explains why the largest moon of Jupiter was called Ganymede, Jupiter being the Roman name of Zeus.

Aquila, together with other constellations in the Zodiac sign of Sagittarius (specifically, Lyra, Cygnus), may be a significant part of the origin of the myth of the Stymphalian Birds, one of The Twelve Labours of Heracles.
