Calisto

•Callisto's Staff: Callisto wields a silver staff with a sharp, crescent-shaped blade. She uses the blade on her staff to attack or cut her opponent. With this blade, she threatens Shun by placing her staff on his neck, indicating that it has an edge capable of cutting or piercing the protection of the Andromeda Cloth. Callisto can also use her staff in combination with her Cosmos. She can shoot arrows formed from energy by moving her staff towards her opponent; the arrows have the power to purify the hearts of her enemies. She can also concentrate her Cosmos to shoot lightning bolts at her opponent. The staff is over a meter long, has a silver hue, with a crescent-shaped blade (which has several details on its blade), and beneath the blade has a small green crystal.

In the moon prison outside the Temple, Callisto goes to look for Tōma, upon arriving at the place where he is, she tells Tōma that the time has come for him to leave the prison, but he replies that she wants him to do, she informs him that he has to go to the Sanctuary of Athena and cut off the head of a Bronze Saint, the angel refuses to take this mission, but she begins to torture him thanks to the mask he wears and tells him that she will remove the mask if he fulfills his mission, in the end Tōma gives in to the request and asks to prepare his Glory.

Artemis explains to Athena that she cannot control time and only a god outside the Olympians can do so, Chronos, the god of time. Athena asks how to find Chronos, but Artemis replies that she does not know his location, so her wish is impossible and she must forget about the human she is trying to save. Space begins to warp, and Shun and Athena are thrown out of the Temple by the distortion. Callisto asks if it is reasonable to let Athena and Shun free after everything that happened, Artemis replies that she should not think about them and tearfully begins to say that her brave younger sister loves humans too much, and this will lead her to endless calamities. After the meeting between Athena and Artemis, Callisto observes that Artemis suffers seeing how her sister can end up in serious trouble due to her actions. After seeing this scene, Callisto thinks that it is best to get rid of Athena before she causes the wrath of the heavens. Callisto goes to find Lascoumoune, and orders him to take Athena's life, upon hearing her Lascoumoune questions if it is right to kill Artemis's sister, but Callisto tells him that Athena's existence only causes pain to Artemis and must keep this mission a secret, she agrees to the mission and asks that everything be left to her deadly technique Crimson Viper. Lascoumoune fails his mission and after regaining consciousness he goes to the Temple of the Moon to report what happened. There, Callisto asks her who had defeated her, she replies that it was the Phoenix and falls unconscious again. Upon hearing this, Callisto thinks that it is terrible that the Saints set foot on Olympus and Athena's insolence has gone too far and they must take her life, since it would be extremely terrifying to awaken the wrath of the gods.

In their quest to find a way to save Seiya from Hades' curse, Athena and Shun head to Olympus to find a way to travel through time. After some trouble and an encounter with Hecate, they finally arrive at the Temple of the Moon. The duo enters the Temple, but are greeted by a hail of arrows; Shun stops the attack with the Rolling Defense. The Satellites prepare another attack against the invaders, but Callisto appears and orders them to stop. Callisto apologizes to Athena for what happened, and although she shows great respect for the goddess, she asks her to withdraw from the Temple, as Athena's evil deeds, which saw her defeat Poseidon and Hades, second only to Zeus, provoked the wrath of Artemis. Athena, however, has no intention of backing down and informs Callisto that she will have to use force if she wants to stop their advance. Callisto decides to escort Athena and Shun to Artemis's throne. The moon goddess sits on a throne surrounded by torches and bathed in moonlight. Artemis asks Athena if she has come to die. Artemis threatens Athena with her scepter. She replies that she is willing to die for her actions, but before doing so, she needs her help to save Seiya's life. Upon hearing that his goal is to change time and steal Hades' sword in the past, Artemis becomes enraged and attacks Athena. The goddesses begin a fight, where Artemis manages to corner Athena. Callisto observes everything, and when Shun tries to interfere, she places her scepter around his neck to prevent him from participating in the battle. Artemis tries to dissuade her sister, but she states that she trusts humans.

Callisto has a phlegmatic character, therefore, she is characterized by being a person who will only speak at the right time, usually keeps a smile on her face, is a person with great manners and shows great elegance when speaking and behaving in front of other people. Although she is a calm and elegant person, she is also a person who is willing to punish those who break the rules or threaten the tranquility of her goddess. When punishing other people she shows an extremely twisted character, since she orders the murder of Athena behind Artemis's back, as well as tortures Tōma to force him to kill Seiya, who can not fight or defend himself due to Hades' curse. All her actions are because she wants to prevent Artemis from suffering even more for the actions of her beloved sister, and to avoid the wrath of the gods for Athena's actions, but still without the consent of her goddess.

Callisto has the appearance of a young adult. She is an attractive young woman with a slim body and fair skin. During her first appearances, her hair was silver, but in later appearances it is presented in a slightly metallic sky blue color; her hair has several curls and is long, reaching a little below the height of her shoulders. Beautiful in appearance, her face has several features that give her a delicate appearance, such as a small nose and mouth, and large green eyes (sometimes they can be seen with a gray hue). Callisto wears armor similar to that worn by the goddess Artemis, but in a silver color, and underneath her armor she wears a dress; the upper part of the dress is black and also covers her arms, while the lower part is white with a skirt that covers her legs until reaching her feet. She holds a scepter with a long, crescent-shaped tip, similar to Artemis's.
