Yukino is a slender, well-endowed young woman with short, light-colored hair and fringes framing her face. She wore a black rose ornament (blue in the anime) on the left side of her head. During her participation in the Grand Magic Games, she donned a cloak clasped together by a star-shaped clip, with feathery protrusions that cover her chest, shoulders, and mid-back, over her blouse and shorts. The cloak flared at her feet, where it is divided into flowing sections secured by ribbons. She wore a black pair of socks that stopped at her mid-thighs.
After her excommunication from Sabertooth, Yukino wears a more casual attire, which consists of a plain white tank-top, with black straps, and a plain black mini-skirt.
Subsequent to becoming a soldier under Arcadios, Yukino wears a dark soldier uniform after the third day of the Grand Magic Games. She currently wears her black rose ornament on her left side of her head.
Yukino is shown to be quite self-confident. She has immense faith in her abilities as a Mage, and takes pride in being a member of Sabertooth - even to the point of betting her life for it. However, while not as cocky as Sting Eucliffe, she does prove to be a bit overconfident, the mentioned bet being made just for the sake of it. She had thought that she had won the bet right from the get go, based on her own knowledge of her power alone.
On the other hand, Yukino highly respects her opponents, and acknowledges the extent of their powers. She is also very polite to others, referring to Lucy and her teammates with the suffix "-sama" despite having just met them.
Despite Yukino's overconfidence and tenacity, she is shown to be very sensitive. The humiliation of having been stripped naked and removing her Guild mark herself greatly lowered her self-esteem. Chapter Upon Natsu showing his kindness to her, Yukino broke down and confessed she is rarely ever treated this way.
According to what she told Lucy, Yukino once had a family consisting of her parents and an older sister, Sorano Aguria. Sorano supported her through most of her childhood in which Yukino felt useless to her family and would always be scolded by her parents. One day, a group of Zeref's followers attacked her family. Her parents were killed and Sorano was captured. Yukino just barely managed to survive the attack. Since then, she has wished to stop Zeref in any possible way, even if she has to go back in time and preventing him from rising to power in order to change history.
Grand Magic Games arc
She is later chosen to compete in the last battle of the 2nd day of the Grand Magic Games against Mermaid Heel's strongest Mage Kagura Mikazuchi, and is determined to win to maintain Sabertooth's title as Fiore's strongest guild. She enters the arena and respectfully greets Kagura and suggests on making a bet like the other competitors did in all of the previous battles. After Kagura initially rejects the bet, Yukino then says that she will bet her life for the battle and Kagura accepts the terms.
After the agreement, the two begin the battle. Throughout the course of the battle Yukino summons Pisces, Libra and Ophiuchus; a mysterious 13th Gate Key, but Kagura easily defeats her and her Celestial Spirits. Yukino falls to ground and begins to tear up over the result of the match and the overall result of the 2nd day, as Sabertooth had gained no points. Before leaving, Kagura informs Yukino that her life now belongs to her with Yukino crying on the ground as she accepts the result of their bet.
After failing to win, Yukino faces the anger of Sabertooth's Guild Master, Jiemma. Displeased by the failure of Team Sabertooth on the second day, Jiemma throws grapes at Yukino's head and forces her to strip, telling her to erase her guild mark, thus banishing her from the guild. She is later seen standing outside Honeybone Lodge, the current lodging of the Fairy Tail Guild over the period of the Games.
Lucy, Natsu and Wendy invite Yukino inside to speak with them. Yukino reveals that she has sought out Lucy to give her Pisces' and Libra's Celestial Spirit keys. She explains that she has been admiring Lucy since she first saw her battle during the first day of the Grand Magic Games. She states that if Lucy takes her keys, the twelve Zodiac keys will finally be together, and that Lucy will "open the gate to the changing world". Lucy, however, refuses to take her keys, stating that Celestial Spirit Magic is all about trust and bonds, and that Yukino is obviously attached to her Spirits and loves them deeply. Though shocked by this reply, Yukino accepts Lucy's answer and leaves, claiming that the twelve Zodiac keys will eventually come together when the time is right.
Before making it down the street, Yukino is chased by Natsu, who wishes to thank her for the offer she made to Lucy, and apologize for his previously rude behavior towards her. After hearing Natsu's words of kindness, Yukino breaks down into tears, confessing to Natsu and Happy that she was kicked out of her guild for losing in her battle against Kagura, detailing how she was forced to strip and remove her mark, and how she felt so humiliated. She then states that she does not have anywhere to go now as she is no longer a part of Sabertooth, and is surprised to see Natsu's angry reaction towards her situation.
The next day, she walks through town with her luggage. She overhears the intrusion at the Sabertooth lodgings and looks back at the Domus Flau, smiling and wondering if it was Natsu who did it. When the third day of the Grand Magic Games comes to a conclusion, Yukino dresses herself in a dark soldier-like uniform late at night to visit Arcadios formally, requesting to speak with him.
On the night of the fourth day of the Games, Yukino stands in Mercurius, pondering the fact that Natsu beat her old guild mates Sting and Rogue in a tag team battle that very day. When asked by a nearby guard whether she has mixed feelings about the results, Yukino replies that she has no attachment to the guild any more, continuing that she is not used to being addressed as "Sergeant". The guard replies that her involvement in the Eclipse Plan deems her worthy of such a title, and the two begin to speak of Arcadios, with Yukino commenting that she believes him to be clumsy, as he is trying to save the world without anyone being aware of it.
On the night of the fourth day of the Grand Magic Games, Yukino travels with Arcadios underneath the Domus Flau, where they see the Fairy Tail Mages summon forth Zirconis, a huge jade Dragon. She listens as Zirconis explains the history of the Dragons to the group, as well as Acnologia's past of once being a human who became a Dragon and the origin of Dragon Slayer Magic. When Zirconis fades away and the Mages wonder about what he said, Yukino reveals herself to the Mages alongside Arcadios, greatly surprising all those present and Lucy in particular.
Yukino watches as Arcadios explains why they were there. She asks Lucy to join them, and if their plan is successful, they might be able to defeat Acnologia. Soon, when they arrive at Mercurius, she asks Lucy if time flows differently in the spirit world, to which Lucy says yes. Yukino tells her that it is the reason they need a Celestial Spirit Mage. Suddenly, the royal army comes and Datong orders them to arrest her, Arcadios and Lucy. As she is being captured, she asked why since he was also on Arcadios' side.
Later, in the prison, Yukino gets depressed, saying that she has always attracts bad luck. Lucy tries to encourage her and asks for her help in escaping. When Lucy starts to express her feelings about the eclipse plan, Yukino says that the mission should be executed. She starts telling Lucy about her elder sister, Sorano, who helped Yukino a lot but vanished because of Zeref. She wonders that if Zeref had not been alive, Sorano would still be with her. 
In her cell, Yukino sits on the ground while hearing Lucy's name being called. She looks up, just to find Mirajane, Wendy, and Natsu are standing outside the door. Natus soon breaks down the door, allowing Yukino and Lucy to escape. Standing outside the cell, the floor collapses beneath them thus landing them in an underground cavern. Looking around, she hears a strange voice announcing this as "Abyss Palace." Noticing a girl above, Yukino recognizes her as the princess of Fiore. Yukino then spends some time looking for a way out, along with the Fairy Tail Mages.
As they search around, Mirajane comments on how Yukino resembles her younger sister Lisanna, causing the Celestial Spirit Mage to blush. Yukino and the Fairy Tail Mages eventually find a narrow pathway to cross. They go through it and discover a wounded Arcadios, shocking Yukino. As they look upon him, they are suddenly attacked by members of the Garou Knights, the most powerful executioners in Fiore. Arcadios warns the Mages that the Magic of the knights is made for killing and as they prepare to fight, Yukino hangs back with Lucy due to both of them being unable to use their Magic. Once the battle begins, Yukino and Lucy are targeted by Cosmos' plant technique but are saved by Pantherlily.
Once Kamika and Cosmos commence their assault, Yukino is nearly consumed the attack until Mirajane manages to save her and the technique is destroyed, creating an explosion. In the aftermath, Yukino ends up with Lucy, Happy, Arcadios and Carla, none of whom can fight as they are confronted by Uosuke, who uses his Magic to levitate Happy. Due to his appearance, Yukino agrees with Lucy when she says they can beat him without Magic. But both of them are shocked to hear Arcadios stating that when Uosuke executes someone, not even their bones are left.
As the two get ready to fight, Uosuke activates his Terrain Effect: Lava Zone, causing the ground beneath the girls to quickly break down into lava. Grabbing onto a ledge, Yukino manages to prevent herself from falling in but finds herself overwhelmed by the immense heat and, like Lucy, has a great deal of trouble hanging on. Telling them the Eclipse can't be done without them, Arcadios steps across the lava and supports Yukino and Lucy from beneath, telling them to meet the princess if they escape. As Yukino manages to get above safety, she attempts to help Arcadios escape. However, Arcadios seems to die in the lava before she can get him out, causing her to call out in anguish. However, he is saved by Horologium, who takes him inside. As Loke arrives, Yukino recognizes him as the lion constellation and then she has her keys returned to her. With her spirits and Lucy, Yukino readies to fight.
Yukino steps up to battle, calling out Pisces. As Pisces attacks, Uosuke attempts to use a new technique, Terrain Effect: Gravity Zone, but Yukino summons Libra to counter, allowing Pisces to attack. However, Uosuke uses Terrain Effect: Whirlpool Zone, which causes Pisces to change into fish due to weakness to water but this allows Lucy to summon Aquarius. With Aquarius, Lucy defeats Uosuke, allowing Yukino and the group to meet the rest of the team as all of the knights are defeated at the same time. Reunited, Yukino looks on in shock as Natsu demands that the knights reveal the exit or he'll execute them.
As Yukino and the Fairy Tail Mages try to find of a way out, she asks Loke if Arcadios is alright. When it is found out that a Jade charm protected Arcadios from the lava, Yukino remarks that the princess' name, Hisui, also means Jade. As the Mages come across a door that opens itself up, a hooded woman appears in front of Yukino and the others. Once Natsu asks her who she is, she begins crying, apologizing and asking them to lend her their strength, at which point Yukino recognizes her voice.
The mysterious person turns out to look exactly like Lucy. Everyone is shocked, and Yukino wonders if it is Gemini. The Lucy look-alike explains that she has used the Eclipse to go back in time, which surprises them. Suddenly, the future Lucy collapses from exhaustion in front of them. They decide to take future Lucy along with them and leave. Yukino attempts to guide everyone out of the Mercurius but is unsuccessful, admitting that the castle has a very confusing layout. She witnesses the Lucy look-alike awaken and listens as she starts explaining her situation, revealing that she is from the future. Yukino feels saddened by her dilemmas and asks about the world in her era.
After hearing about the upcoming troubles, Yukino is left shocked and leaving her to wonder why such a thing will happen. As Carla asks about what will happen to them in the future, the answer is met with silence. Yukino begins, thinking it happened because they were with her. As the future Lucy explains that she traveled back to July 4th, Yukino listens as she suggests that they meet with Jellal, who should be preparing a strategy. Soon after, Natsu thanks Lucy promises to protect the future, with Yukino looking on sadly. Unnoticed, Yukino parts ways with the Fairy Tail Mages and future Lucy. Elsewhere, with a bitter expression, she looks down towards the floor.
Yukino is found sometime later by Mirajane, leaning up against a wall, dispirited and alone. When asked by Mirajane to come with her, Yukino rejects the offer, stating that if she does so, misfortune will dog their every step. She relates how it has always been like this, that people around her have always been extremely unlucky because of her presence. When Mirajane replies that none of her friends are the type to blame others for their bad luck, Yukino tries to deny the other's kindness, and begins to cry. She is shocked as Mirajane embraces her, comforting her with the knowledge that she has a meaning in life, no matter how small it may be.
Having her confidence revived, both Yukino and Mirajane head towards the courtyard that the Eclipse Gate is situated in, arriving to find Lucy helplessly trying to close the Gate by herself, but failing due to her lack in Celestial Spirit Magic power. Running towards her, Yukino shouts that they have to summon all twelve of the Ecliptic Zodiac together, and that the Spirits will have the power to seal the Gate for them. Throwing her two keys into the air, Lucy does the same, and the two clasp hands, together summoning all twelve Spirits at once. Maintaining their Magic power, the two manage to keep the Spirit's Gates open for long enough that they allow them to completely shut off the Eclipse Gate, stopping the Dragons from accessing it. Happy that they succeeded in saving Crocus, Yukino and Lucy are then shocked when the Future Rogue appears, the man being annoyed at them for their interfering ways. When Future Rogue then demonstrates his ability to manipulate the seven Dragons that managed to make it to Crocus, Yukino stares on in complete disbelief, openly questioning what motive Rogue could possibly have with wanting to use the Dragons to destroy the world. The Rogue of the future does not answer though, rather sets Zirconis on the group as he flies away.
Yukino is shocked to see Zirconis alive, who is wondering which one of the group he should eat. However, her reaction becomes that of a shock and embarrassment when she witnesses what his Magic can do: strip people of their dignity, by removing their clothes from them. On the ground, Yukino watches as Zirconis mocks Wendy, and cries out in worry when the Jade Dragon grabs the now-defenseless, and nude, Lucy. However, Zirconis, upon hearing Wendy state that she will defeat him before he can devour Lucy, then begins to rage, creating shockwaves with his stomps, which sends everyone who remains atop Mercurius, Yukino included, flying backwards. Yukino then cries out in worry, once again, as Zirconis, who is now airborne, throws Lucy towards Crocus.
