Aeson of Crateris

Aeson wears a corrupted version of the Cup Cloth, his entire body covered by a long white cloak that only leaves one shoulder pad of his Cloth exposed. His torso is covered on the right side by a piece of cloth, similar to an Arab military scarf or bandana. Aeson has light or white skin, is a tall man, has somewhat long hair that reaches slightly below his neck, and has a ribbon around the top of his head. The appearance of his face and his hairstyle make Aeson physically similar to Aiolos.

Aeson seems as wise and determined as his companion Rigel. He showed gratitude to Eris for the new life she granted him and considers his only duty to protect the deity who granted him this new life. In the past, he was considered a nobleman who was always willing to heal the wounds of those around him.

Aeson was a noble Silver Saint who used his medical knowledge and the special ability of his Cloth to heal the wounded in the Sanctuary. Around the time of Athena's arrival on Earth, the Patriarch (impostor) ordered the assassination of the Saintesses and attempted to kill baby Athena in order to take control of the Sanctuary. Athena was saved by Aiolos, who fled the Sanctuary with her in his arms. The Pope ordered Aiolos to be hunted down and killed. That same night, in another part of the Sanctuary, Mayura flees with Olivia's daughters, but before she can leave the Sanctuary, she is intercepted by Shura, who attacks her, considering her a suspect. However, seeing that she is willing to sacrifice her life for the girls, he decides to let her go. Mayura lies wounded on the ground, but at that moment, Aeson appears, tending to her wounds and asking her to drink the miraculous water from his Cloth. He also trained Rigel of Orion, to whom he told that the power of a Saint does not exist to defeat others, but to protect Athena and all the people of the Earth. After the beginning of the war unleashed by Eris against Athena and the Sanctuary. Rigel is outside the door that leads to Eris's throne, when at that moment he feels the presence of someone approaching and asks who it is, since only those who were called by the goddess can be in that place, upon hearing these words, the invader says that he is arrogant to believe himself the only special being in that place. The invader begins to approach, Rigel recognizes him and with great respect refers to him by the name Aeson. Rigel asks the reason why he was chosen, but does not get a real answer from Aeson, who only limits himself to saying that they only have the duty to protect that divinity that granted them these new lives.

At that moment, the two feel an explosion of cosmos unleashed by Eris. Rigel realizes that the goddess is suffering but seems happy, and Aeson tells her that they have little time to bring Shōko before Eris. Rigel goes in search of Shōko to take her to Eris, when he meets her, the young woman agrees to accompany him. Rigel and Shōko arrive at the gate that leads to Eris's compound. Aeson meets them in front of the gate, seeing Shōko he asks her who has she come looking for? since that is where his sister and Athena's soul are, to which she replies that she has come for both, upon hearing his answer he tells her that only two people will be able to return, even so she is willing to continue forward, but the young woman is determined to go ahead, so Aeson explains that they must hurry, because the Temple has begun to collapse and they must go while that compound remains silent. Aeson observes the appearance of Atë in front of Eris's compound. Atë tells Rigel and Aeson that they did a good job bringing Shōko here so she can kill her. Rigel mobilizes to defend her, and Shōko begins to attack her. At that moment, to everyone's surprise, Eris emerges from her enclosure to speak with her sister. Aeson silently watches what happened between the two sisters, until Shōko is injured by an attack from Eris. And, with the arrival of Saga, everyone retreats to the sky along with their goddess. Goddess Eris and Saga begin their attack on the Sanctuary. Saga uses her power to destroy the Goddess Star and with her Another Dimension throws the fragments towards Planet Earth. The Gold Saints defend the planet from the meteorites. On Star Hill, Mayura destroys a meteorite to protect the Saintesses, then orders them to go to Athena while she throws them away. Mayura remains on Star Hill to fight the enemy that arrived with the meteorite she destroyed.

Mayura recognizes her enemy as Aeson, however, she thanks him for helping her in the past, although he now presents himself as a servant of Eris. Aeson explains that he swore to protect Olivia's daughters. Mayura wants to know what he is doing there, because she will not allow him to destroy this sacred place. Suddenly, Mayura senses Olivia's cosmos. Aeson explains that Olivia's body has been locked for 13 years inside the temple of Star Hill. She understands that his goal is to take over Olivia's body and tells him that it is a shame that she has fallen so low, but he replies that he is now a servant of Eris. She states that she will destroy him with her Higi Kenyoku Tenbusho, however, Aeson dodges the attack by entering the temple, as he does not wish to fight. Inside the temple, Mayura chases after him while screaming at him not to let him take over the body, but Aeson says that he doesn't have to worry because Olivia's soul rests in peace unlike him, and Eris only wants her body. Mayura asks why they want Olivia if she died thirteen years ago, to which Aeson replies that she knows well that Olivia is the embodiment of a miracle. Just then, Aeson finds Olivia's body, which remains unchanged. Mayura is shocked by the appearance of Olivia's body. Aeson says that she carries divine power from "that time", so her body does not degenerate, therefore, her miraculous body will become a vessel for Eris's soul, who will replace Athena as the goddess of the Earth. He thanks Mayura for helping him and looking after the girls until now, after this, he attacks her with a powerful cosmos blast that lights up Star Hill.

•Hisō Byaku Renge: This technique begins as a defensive technique, as water molecules condense into the moisture in the atmosphere and form a force field-like barrier, similar to a reflecting pool of water, in front of Aeson's hands. The next step in the technique is to solidify the water molecules, which take the form of ice spears. The opponent is then impaled on the multiple spears Aeson has created. This technique can work for both defense and offense. •Hisō Byaku Gasenran: Aeson concentrates his cosmos projecting a whirlwind composed of several ice spears onto his opponent. •Kholodnyi Smerch: It is an exclusive technique of the Saints who handle the cosmos with cold air since they concentrate their cosmos and launch a whirlwind of cold air that freezes their enemies. •Koltso: This is a paralysis technique that uses rings of cold air to surround the opponent and inhibit their mobility. The user fires a small puff of ice crystals at their opponent with their index finger. Upon reaching the opponent, these crystals form a ring around the victim's body that quickly unfolds into several ice rings. The number of rings increases with time, and they close ever more tightly around their prey, momentarily paralyzing them. •Brilliant Lavina: This technique involves accumulating ice fragments to form a gigantic freezing wave whose temperature approaches absolute zero. When launched in the form of an avalanche, it instantly shuts down all vital functions of its victims.
