Elaine

"I wish what he came to steal wasn't the Fountain of Youth... but me..."

- Elaine expressing her desire in Bandit Ban

is King's younger sister and the Holy Maiden who guarded the  Fountain of Youth. She was killed by a demon in the Fairy King's Forest after giving up the fountain to Ban, but was later resurrected by Merascylla of the Ten Commandments.

Appearance
Elaine has long and thin eyelashes, and blonde hair that reaches her neck. She wears a single white one-piece sleeveless dress which is tied together with a butterfly knot at the back. She resembles a human child, despite being around 1000 years old.

Personality
Elaine is shown to be a kind, caring and forgiving girl, who cares deeply for Ban and is willing to forgive King for abandoning her and the kingdom, but is slightly disappointed and unhappy that he did so. Due to several humans repeatedly trying to steal the water of the Fountain of Youth with malicious feelings, Elaine came to distrust humans, but soon came to trust Ban when she read his heart, and even started to have feelings for him. Like her brother, King, Elaine becomes bashful and embarrassed easily when it involves Ban in embarrassing situation.

Due to Ban's encouragement in trying out ale, Elaine became angry or high drunk as seen in the OVA.

After being revived by Merascylla, Elaine became darker and is hostile to anyone who's near or spends time with Ban regardless if they're friend or foe. Though, she eventually returns to her innocent, kind-hearted nature after she expels Merascylla's influence thanks to Jericho and Ban.

History
Seven hundred years before the beginning of the series, Elaine's brother, the Fairy King Harlequin abandoned the kingdom to go out and save his best friend, Helbram and other Fairies, forcing Elaine to become the Fountain of Youth's Guardian Saint, live hundreds of years of solitude, and preventing her from leaving the Fairy King's Forest. As time passed, Elaine came to distrust humans as an aging king who dreamt of ruling forever sent an army to invade her country; a merchant who dreamt of endless riches and attempted to steal the Fountain of Youth from her; and finally a savage tribe attempted to burn the Fairy King's Forest down with her but all of those attempts were thwarted by herself.

Bandit Ban
At some point during her life, Ban, then known as Bandit Ban, wanting to gain immortality, climbed the gigantic tree, in the Fairy King's Forest, where the Fountain of Youth was located. Elaine, thinking that he, like all other humans who desired immortality, had malicious feelings, quickly blew him off the tree with her wind manipulation abilities. He, still being alive, persistently kept climbing up, and she, kept blowing him off, with the actions of each angering and annoying the other. As Ban then removes his three-section staff and prepares to fight her, she also does so. Seemingly attacking her, Ban then manipulates his weapon to instead grab the cup which has the water from the fountain, surprising Elaine. Before he could drink it, she immediately immobilizes him with the branches of trees.

Elaine then tries to explain to him that without the fountain, the forest would die, and soon realizes, by reading his mind, that he has no malicious feelings, and unbinds him. Some time later, after asking him his name and the reason he wants immortality and receiving the answer, she informs him that she had been protecting the fountain for seven hundred years in the place of her brother, to which he responds, commenting that it must have been "boring as hell", and irritating her. When he then proceeds to leave the forest, she is seen dejectedly expressing her desire for him to have stayed there for a longer time. However, he soon comes back up and says that he had gone down to get his Ale collection book, which he had dropped when he was blown away by Elaine.

During the next seven days, both of them become good friends, with Elaine even starting to have feelings for him. Sometime later, when Elaine states her desire to go out of the forest with Ban, he hears her and questions her if she actually wants to do so, and as she tells him to not make fun of her, responds, saying he is serious and that he doesn't get along with people particularly well. She, however, denies his offer, explaining that she had to protect the fountain, leading him to then offer to find her brother and bring him back, which will relieve her of her duties and allow her to go of the forest. Hearing that, she hugs him, which surprising him.

Just then, a demon from the Demon Clan started burning the Fairy King's Forest with its purgatory fire. Ban instructs her to take the fountain's cup and escape, and then uses his three-section staff to remove the demon's heart. She, however, tries to stop him and inform him that demons have multiple hearts; the demon then immediately and fatally wounds both Ban and Elaine with its claws. In desperation, she makes him drink the water through her mouth, since he did not have the strength to drink it himself, thus making him immortal. After the demon is defeated by the now-immortal Ban, and the whole forest burns due to its purgatory fire, a dying Elaine gives him an almoca leaf, which is the forest's last seed, asking him to plant it somewhere. Ban then tries to declare that he will definitely "make her his", but is cut off by her death.

Capital of the Dead Arc
After coming to the Capital of the Dead, Ban immediately senses her to be nearby, and when she flees, chases her, himself being chased by King. She then watches as King and Ban battle, and after the former petrifies the latter with his sacred weapon, flies toward Ban and kisses him, thus releasing the petrification, surprising King. As she and Ban share their reunion, she refuses King's requests to let him see her, since she was still angry at him for abandoning the kingdom. They then feel the ground rumbling due to Guila's power, and before Ban rushes to fight her, she questions him as to why he had come to see her. When he answers that he just wanted to tell her that he will definitely make her his someday and then leaves, she happily thanks him, while King is angered by Ban's words. As Ban battles Guila, she is seen worrying about him.

While the battle continues, King expresses his perplexity at Elaine "forgiving" Ban, the man who he thinks had killed her. She then informs him that after he had abandoned the kingdom, and the 700 years she lived in solitude were brightened up by Ban in just a week, and also informs King that Ban had purposely provoked him into attacking since he discovered him to be her brother. She also adds that Ban is not the person King believes him to be, explaining that King now being able to see her is because of her wanting him to understand Ban and help him. Just then, Elizabeth and Hawk encounter them while trying to flee the battle that is still ongoing, with her then disappearing as King questions her for the reason she cares for Ban. During King's battle against Guila, she states that she was confident of him granting her wish of him helping Ban, that his power is greater when he wields for others, rather that himself, her knowing of him blaming himself for the destruction of the kingdom, and that he shed countless tears for their death.

As Guila is defeated, she continues to explain the human kingdom's alliance with the fairies' forest, and reveals King to be the Fairy King Harlequin, the lord of the fairies, the one that was most respected, and the one who repelled all the invasions to the fairies' homeland. After Guila is defeated, Elaine appears near the group, theorizing that she returned to the living world due to the impact of the resulting explosion, since the Holy Knight, unlike Ban and the others, had come to the Capital of the Dead with only her soul and not her body. As everyone's bodies then start disintegrating, Elaine explains the phenomenon to be due to the world, which is for the dead, rejecting the living, who do not belong there. After the both share their final goodbyes, she then thanks King for protecting Ban.

Albion arc
When Ban, King and Jericho traveled to the newly-regrown Fairy King's Forest, Elaine's body was placed in the tree where Ban pays his respects and vowed to find a way to bring her back from the dead. As the Fairies started blaming Elaine's death on King, Ban berated them that Elaine would have not been pleased if she found that he killed his best friend Meliodas just to bring her back. Meanwhile, Helbram's spirit within his helmet revealed to King that he brought Elaine's message from the Capital of the Dead to protect Ban for her. When Merascylla summons souls from the Capital of the Dead to create an army, Elaine's soul was one of the souls called back to the living to join the demon's army of Zombies.

Ravens arc
Now resurrected, Elaine begins to wander around the new Fairy Forest, much to the surprise of Gerharde and the rest of the Fairies. The Fairies then begin to cheer about Elaine's resurrection and how it's a miracle. Elaine then states to Gerharde she noticed how long hers and Ban's conversation was and also pointing out to the other fairies how they were surrounding Ban and having a great time. Immediately, Elaine releases Mannpuu no Gekirin on the fairies and tells them that Ban is hers and it was unfair they were talking to him. She then goes over to Gerharde and angrily points out she hurt Ban, immediately harming her with Sokokaze no Gekirin. After finishing her work, red leaves begin to swarm around Elaine and form a red dress and shoes. Now fully clothed, Elaine happily calls out to Ban to wait for her. She then begins to summon Oslow to come to her.

Arriving after Ban killed one of the newly resurrected, Ban notices Elaine's arms behind Jericho, trying to slice her throat. Ban immediately pushes Jericho out of the way and is shocked to see that the attacker is Elaine. Noticing the blood on her hand and Ban's slit throat, Jericho starts to yell at Ban to get away from her but is completely ignored as the two lovers reunite with a passionate kiss.

When separating from their kiss, Elaine expresses to Ban she missed him so much and then passionately kisses him again. Only to have Ban pulls her in closer to deepen the kiss. Jericho, still freaked out about the events, screams at them to keep it in their pants and asks Ban how he isn't even phased by what just happened. Not phased, Ban explains to Jericho that it is Elaine and there's nothing to worry about. Jericho tries to reason with him by point out she slit his throat only to have Ban explain he's healed now so there is no issues. Elaine looks at Jericho and immediately announces her dislike for the Holy Knight Apprentice, attacking her on sight. Ban tries to explain to Elaine there's no need for that only to have Elaine express there is a need for this and attack Jericho again.

After sending Jericho flying, Ban grabs a hold of Elaine's wrist and tells her to stop again. Asking why he's protecting Jericho, Ban explains to Elaine she's his woman and his only woman, only to be attacked violently by Elaine. She goes on to explain that she had been watching for quite sometime and it makes her angry to see Jericho traveling with Ban because it's her dream to travel with him. Ban, realizing Elaine is being controlled, screams to Jericho to take cover. Jericho, then tries to attack Elaine, dodging all her attacks and then tackles the Fairy to the ground. Ban screams at Jericho once again to stand down only to have Jericho to start asking if she really does love Ban.

Elaine begins to chant at Jericho that she does love Ban only to have Jericho confess she loves Ban as well because he's her savior. Elaine points out to Jericho that Ban will never look at a girl like her and therefore, Ban will never return her feelings. Upset, Jericho bursts that her chest size is bigger compared to Elaine's and has more curves, making her more suited to Ban. But it's obvious to Jericho that Ban's love for Elaine is endless as she noticed he calls Elaine's name in his sleep, thinks about her when he's drunk or sober and how dedicated he is to try and bring her back. Jericho goes on to say that she knows Ban doesn't feel the same but she loves him enough to never hurt him and then calls Elaine shallow for allowing herself to be controlled by someone, even to the point she screams that if Elaine really loved Ban, she wouldn't have allowed herself to be controlled and harm Ban. Crying, Elaine states she knows and feels terrible for all of this. Immediately, Elaine pushes Jericho off of her and attacks her, screaming out loud for someone to stop her.

Ban then embraces Elaine and begins to ask her if she remembers that he told her he would make her his and she is his, forever. Upset, Elaine apologizes to Ban, stating she didn't want him to see how dirty and soiled she's become, Ban tells her that he's the Fox Sin of Greed and he'll come and steal all her skeletons away. Then, he offers to take her on that journey he promised long ago. Smiling, Elaine is about to say yes but suddenly becomes limp in his arms. Worried, Ban begins to scream Elaine's name as she writhes in pain. Jericho rushes over to see if the fairy is ok as Ban begs Elaine to hold on. As the two worry over the Fairy, Merascylla and Galan arrive at the scene. Merascylla explains that Elaine is under the effects of Onhangon no Hou. Because of the fact Elaine's grudge had disappeared, she is beginning to suffer for it and it is only a matter of time before she dies again. Angered, Ban looks at the two demons and hands Elaine over to Jericho for her to watch over her as Ban prepares for battle against the two demons. After fighting Galan and Merascylla, Ban then grabs Jericho and Elaine, as he retreats while the demons are temporarily injured. After travelling a few dozen miles, Ban collapses due to exhaustion and explains hat he was saved by Zhivago, who appeared before Galan and was eaten in Ban's place. After asking Jericho to take Elaine and run, she refuses and instead, she promise to carry them to safety.

As Jericho carries Ban and Elaine away, Galan and Merascylla start toying with them by throwing boulders at their location. They miss twice, before the third one hits the ground and send the group tumbling off a cliff. Thanks to Elaine, the three of them land safely near a dark cave. Inside the cave is an open bar with a lone bartender inside. As they enter, the bartender greets them to his store: "My Sweet Gluttony".

The bartender who recognizes Ban backs away until Jericho tells him that the Seven Deadly Sins are no longer considered criminals. The bartender urgently asks about Merlin's condition, but is left hanging as Galan and Merascylla find the bar. Ban, Jericho, and Elaine quickly hide from the two commandments.

As night shifts to day, the bartender, who reveals himself to be the Lion's Sin of Pride, Escanor, decides to play Galan's deathmatch. After Escanor defeats both Galan and Merascylla, night falls and Escanor returns questioning Ban about everything that has happened in the last 10 years. With Elaine in Ban's arms, he asks if she's ok, and she responds with feeling better than she was and Ban agrees. Jericho says that she should be fine since her only regret is not being with Ban. Elaine smiles, saying that Jericho is the best. The reunion between the two sins is then cut short as King and Oslo arrive. King is shocked that Elaine is seen before him, as she happily calls his name.
