Diane

Diane (ディアンヌ) is a member of the Seven Deadly Sins, titled the Sin of Envy, with the symbol of the Serpent. She is a member of the Giant's Clan, and is thus much larger than ordinary humans, and even her fellow Deadly Sins. However, Diane has left the Giant's Clan for unknown reasons.

Appearance
Being a giant, Diane is several times larger than ordinary humans. She is a far maiden with pink eyes and medium length brown hair which is tied up into large twin tails. Her attire consists of a one piece orange suit, boots that extend almost up to the knees, and a metal armband which is embedded with shiny metal pebbles. She also wears an orange colored short sleeved bodysuit and boots.

Diane's wanted poster depicts her with light colored hair. Her symbol, which is of the Serpent, is located on her left outer thigh.

Personality
Diane is a very friendly woman, and is also very confident regarding her abilities, appearing to generally consider Holy Knights as weak. She cares very much about, holds very strong feelings for Meliodas, often cuddling him to display the same, and becoming very delighted at complementing statements. Her feelings are strong enough for her to overcome her fears for his sake. Diane is very quick to throw temper tantrums, and often does so upon becoming upset.

Since, due to her size, she cannot help Meliodas in any way other than fight for him, she has expressed her strong desires to be smaller, contrary to Elizabeth's desires of being strong.

History
Many years ago, after Diane had left the Giant's Clan, she had entered into a petty argument with a group of knights, who treated her very discriminatively for being a giant. Meliodas, stopping them, then questioned Diane if she was frightened; his having treated her as he would, a normal girl of his size made her feel as though she was his size, i.e., small.

10 years ago
The Seven Deadly Sins, including Diane, were summoned to a castle to meet the Great Holy Knight. When they find him dead, they are ambushed by all the Holy Knights in the kingdom, with Diane later being able to escape and reach the Forest of White Dreams, where she forced the indigenous Prankster Imps to hide her, lest she go on a rampage.

Introduction Arc
Diane's wanted poster is displayed on a board within the Boar Hat.

Forest of White Dreams Arc
The defeated Prankster Imps retreat to a sleeping Diane, inadvertently leading Meliodas, Elizabeth and Hawk to her. Diane wakes immediately upon hearing the Imps' apologies for allowing a Holy Knight come through, since they believed Meliodas to be one, and then instantly grabs Meliodas with a hand. After realizing his identity, however, she cuddles her captain, and when Elizabeth introduces herself to be traveling with him, throws a tantrum. Meliodas, after calming Diane, begins a discussion on the day the Deadly Sins were framed for the Great Holy Knight's murder. However, he also reveals that he has almost no memories of the day they, and then narrates the only memories he has, which end with someone apologizing to him, addressing him as "captain".

This leads Elizabeth to speculate the existence of a traitor, and Diane, to declare that she will help Meliodas no matter the foe. Few moments later, Hawk notices a gigantic thundercloud in the sky, from which a lightning bolt descends and immobilizes all of them, with Elizabeth introducing the assailant Holy Knight as Gilthunder. After he leads her away, ending her interruption, he expresses his desire to fight Meliodas, and reveals his connection to Zaratras, the Great Holy Knight. Before the battle, Meliodas and Diane easily break his immobilization themselves, and the former instructs the latter not to interfere. Diane quietly observes the battle, watching worriedly when Meliodas is gravely slashed. When Gilthunder continues attacking Meliodas and refuses to end the battle, Diane grabs him, and ignoring his attempts to escape her grip, flings him from the the forest. Sometime afterward, Diane leaves along with her captain, Hawk, and Elizabeth. Meliodas decides to head for Baste Dungeon, where Ban is imprisoned, leading Elizabeth to object, citing his grave wound at Gilthunder's hands. Though he affirms her that it is not major, he soon collapses.

Baste Dungeon Arc
Diane, Elizabeth and Hawk then travel to a town near the Baste, named Dalmary, in order to have the severely injured Meliodas by Dana. As she sits next to Dana's house, she is watched with discriminatory wariness due to being a giant. Not longer, Diane decides to head to the dungeon herself, retorting that Elizabeth would be only a hindrance when the princess asks to join. Elizabeth replies her desire to be of use, and that Meliodas was taking on "more than he can handle". This angers Diane, her saying that Meliodas was not doing so for the princess alone, and that such was his usual personality. She continues, narrating the episode her and her captain's first meeting, and his treatment of her at that time. As Elizabeth declares her wishes of wanting to have strength, Diane declares her own of wanting to be small. Abruptly, Hawk notices a huge swarm of poisonous insects flying toward Dalmary.

Although initially plagued by her fear of insects, Diane overcomes it and quickly kills them by raising huge pillars from the earth, much to the surprise of Friesia, the assailant. While Elizabeth and Hawk awe at Diane's ability, and she leaps out of Dalmary and, handing Elizabeth the duty of taking care of Meliodas, starts running toward the Baste Dungeon. Diane, later on, encounters Meliodas, Elizabeth and Hawk when the three are walking to the Baste Dungeon. She mysteriously seems to have no recollection of having defeated Friesia and having left for the dungeon previously.

She tries to recollect, when she suddenly finds Meliodas and Elizabeth to have vanished, and Ruin to be standing in their place. When the Holy Knight claims to have already captured them, she attacks him, but is soon revealed to be under an illusion that deludes her into seeing Ruin in Meliodas' place; she thus attacks Meliodas while believing that she is attacking the Holy Knight. Meliodas, immediately flees along with Elizabeth, and Hawk, and upon finding two civilians walking nearby, takes them along. As the five hide, Meliodas also falls under Ruin's hypnosis. Seeing Ruin in Diane's place, he, thinking he is attacking Ruin, jumps up, rolls and slashes from above, with Diane blocking it with her fist and responding by raising sharp pillars from the earth toward him, with he in response deflects. Diane and Meliodas' battle continues, uninterrupted, and only stops when Elizabeth manages to remove the source of Ruin's illusions - his staff's bell.

Later, during the aftermath of Meliodas and Ruin's battle that ends in the latter's defeat, Diane quickly defeats Friesia with a punch that utterly crushes the Holy Knight. Walking towards the heavily injured Elizabeth, Diane removes her giant backpack, intending to place her inside and take her to the town for treatment. Elizabeth, however, requests to be taken inside Baste, to which Diane complies. The second, and older shepherd is revealed to be a soldier who was ordered to act as a civilian. When he refuses to reveal Ban's location due to fear of his superiors, Diane threatens him while holding Friesia's defeated body. Inside, the group encounters Cenette and Ban. As Meliodas and Ban greet each other, and arm wrestle, thus destroying the entirety of Baste, Diane simply watches as though this was a common occurrence. The group, along with Cenette and the other villagers, return to Dalmary where Diane looks after Elizabeth.

At night, during the party, Ban is formally introduced to Elizabeth; Diane has to stand while eating due to her size. During the party, Elizabeth expresses her joy, but states that the events in Baste have reminded her all the more about the Holy Knights' frightening abilities. Diane replies that while she is not interested in human kingdoms, she has no qualms with fighting for Elizabeth, since she was "really cool" that day, and did have powers: the power to move her and Meliodas' hearts. Diane also asks Elizabeth whether she could henceforth address her as merely "Elizabeth", instead of "princess", and then tells the young lady to address her as just "Diane".

Capital of the Dead Arc
Diane and the others left Dalmary Town to travel on the road again to find the other Sins. When Elizabeth apologizes to her for making them wait when she needed to heal but Diane said she shouldn't worry too much. When Meliodas was about to say when they should be going a group of two apprentice Holy Knight who want to know where are they going and who are they because of Hawk mother and Diane being from the Giant Clan. Meliodas came out and told them that they are a traveling bar and that Diane and Elizabeth were they attractive waitress. The plan was working until Diane hugged Meliodas and call him captian because she was happy being called attractive.

When the apprentice Holy Knight was about to attack a Black Hound attack and killed them! Meliodas scared it away by using his power and they continued on they traveling. Meliodas told them that they are going to the Capital of the Dead to find King. When they got to a village next to the Capital of the Dead, they decided to find information to find King or how to get to the Capital. Meliodas pick Diane to be a attrative waitress to bring in customes which she was happy and Ban as the cook. Diane was standing outside all day to call people in but nobody came because the villages was empty? The Sins realize that Ban left before starting business and deicded to go out and find him. When they found Ban fighting someone, Meliodas stopped him and show who it is, both Meliodas and Diane recognize that person is King much to Ban shock. Diane went to him and told him that they been looking for him but King turn the other way and left. Diane and the others went back to the Boar Hat and were serving food to a local girl named Ellen and her brother.

They got a information that King wanted to go to the Capital of the Dead and told them how do get there.When they left Diane was wondering why King left. When they got there the flowers around them started to move and made a wind which send them to the Capital of the Dead. Ban left the group to follow something and they saw King was following him too? When they were trying to find them, a Holy Knight appear to them and her named was Geera and she said she killed herself to get here! Meliodas sense how dangerous she is and told Elizabeth and Hawk to leave. Geera launches an attack that and sends the two Sins flying, but Meliodas manages to catch Meliodas before she fell on a sharp cystal.

Geera then comments that the capabilities of the Giant Clan and Diane's ability, "Creation", are not very impressive. As a response, Diane demonstrates her abilities by using hand seal signs and made her move Sand Whirl and trap Geera in it but Geera easily frees herself with a blast from the tip of her rapier. She forces Diane back with another explosion but later she came back and try to crush her but she dodges it with ease and explosed her again. But when seem at last Ban came back and used his ability Snact but she got herself freed by using her power Explosion. The rest try to fight Geera together but she was too powerful and when Geera explosion Meliodas, Diane came in the right time and saved him much to her joy of how she saved him.

Diane was now blocking all of Geera attacks and now Diane is heavliy wounded and couldn't move. But then King came in and told them that he is here to help them. Geera then sent a multiple of attacks toward them but King easliy block them all with his spear. Geera comment on his spear power and wanted to fight all the Sins but King said he wanted to fight one on one with her only and told the other to rest now. After King defeated Geera, the rest of the Sins bodies were disappearing because the Capital of the Dead is rejecting them and are about to go back to the living world. When they got back they saw that Geera was there by still in near death and Meliodas offers to do something to her. Later the Sins stop to rest somewhere and Diane was better now.

King was worry that Diane might still be injury from before and told her to rest but Ban told him that she might have Capital of the Dead Arcfaked it, so that Meliodas might pay attention to her much to King angry. Elizabeth comment at King how strong he was which got King thinking and told the Sins that they could have beaten Geera with ease like him with they sacred treasures and told them what happen to them. To King shock he found out that the other Sins no longer has them, Diane lost hers somehow. King was now yelling at Meliodas and Ban for not having these but when he saw Diane doing a sad cute look, King told her she lost it and nothing can be help.

Byzel Arc
The next day, Diane is left behind at the Boar Hat while King, Meliodas, Diane and Hawk travel to Biron, since she is easily noticeable. Later, she throws a tantrum at similarly not being able to accompany them into Byzel. Elizabeth offers to join Diane in house-sitting, and when Diane replies that doing so will be boring, responds that she wants to have some "girl talk" once in a while, then heading into the forest with the giant to gather ingredients for dinner. As they walk into the forest, Elizabeth finds a mushroom-like monster, which Diane, considering it an ingredient, tries to grab. The creature, realizing that it is in danger, releases spores that shrink both Elizabeth and Diane. The latter wears the former's clothes and jewelry, in order for them to not be lost, and then, wanting to surprise Meliodas, enters the Byzel Fight Festival under the name of "Matrona", with the shrunken Elizabeth hiding in the shrunken Diane's bosom.

As Matrona
The shrunken Diane is first seen during the preliminary of the fighting festival, in which, she quickly and easily defeats more than ten men with her abilities, thus advancing. Afterwards, she is seen drawing the lots which will determine her next opponent, who is Griamor. She then turns away from Meliodas and King's direction, probably wanting to hide "her" identity. As her battle, Love Helm, the referee, requests her to remove her cape, in case she had any concealed weapons. She does so, revealing her incredible identicalness to Elizabeth. Her identicalness revealed, Veronica and King ponder about her being Elizabeth herself. Griamor, stating that the moves she and displayed in the preliminary were impossible for a frail lady like Elizabeth, when Veronica asks him to stop the battle, readies himself, with Diane, as the battle begins, immediately and with great speed, attacking Griamor relentlessly. The punches are, however, negated by the Holy Knight's ability, which is called, "Wall", and creates a circular, and defensive magic barrier, which cannot be affected by physical attacks or ordinary magic, around himself. Diane struggling with the barrier's omnidirectional expansion, Griamor states his intentions of merely pushing her out of the ring with it.

He then states that he will humiliate Meliodas next, enraging Diane. She, declaring that she will not let that happen, destroys the barrier with a single fully powered punch, and then, with the same punch, punches the much larger Griamor in the neck, sending him flying out of the ring, surprising both Veronica and Hauser, and causing Metrona's hat to fall off.

As "Matrona" is declared to be the winner of the first battle of the first round, her facial appearance is revealed to be identical to Diane's, with King and Ban immediately recognizing her. She walks toward the three Deadly Sins, stating that she had wanted to keep it as a secret for a while longer, but is only greeted with Meliodas questions her as to who she was. His dullness having angered her, Diane punches him in the stomach and storms off, turning back when King chases after her, and asks her about her body became much smaller, and about where Elizabeth is. In response to the last question, Diane replies that "she" is right there, with an expression of Elizabeth's.

However, it is actually a seemingly shrunk Elizabeth, who seems to be between Diane's bosom, that replies to King's question, surprising him. Diane, explains as to how she and the princess have shrunk, and that she borrowed Elizabeth's clothes, and her jewelry, since they do not want them to be lost. Hearing the strange effects of the creature, King theorizes it to be a Chicken-Matango, a timid mushroom-like creature whose spores can shrink creatures. As Meliodas questions Diane as to why she hadn't informed them of this before, she, jumping toward him, merrily states that she had wanted to surprise them, and, as she is held by the unwilling young man, states that she had always wanted to be held by him in this manner.

She then immediately asks him to put her down, and then to grope her all over the body, the same as how he often gropes Elizabeth, much to King's temporary relief and subsequent nosebleed. When Meliodas refuses to do so, she becomes upset, and then states that since she is usually huge, her captain doesn't care about her. In response to her upset, he pats her on the head, comforts her, and explains that he couldn't act that way to an individual as important as her, to which she blushes. Much to Meliodas' annoyance, however, she then immediately huge him, while merrily declaring that they could now have children.

Diane then watches Cain and King's, and then, Meliodas and Ban's battles. When, as the latter battle continues, Meliodas seems to be weakening more and more, Diane wonders the reason for that. Answering her question, King notifies her that just as Meliodas become sluggish, Ban had become more agile, explaining that Ban's ability, Snatch, enables him not only to "rob" physical objects, but also physical abilities such as speed and stamina; the reason why Meliodas was on his knees without receiving any damage was that Ban had "robbed" him of his physical abilities. After Ban completely steals all of Meliodas' abilities, and questions Meliodas if he will give up, or be utterly defeated, Diane, from the audience, yells at him that if he further harms Meliodas, she will not forgive him and will cut their ties. Elizabeth pleads to Diane and King to stop the battle, and Diane states her hypothesis that Meliodas is baiting Ban to delivering his most powerful blow, and will then reflect the blow with Full Counter back at Ban. King, however, explains that doing so would be impossible - Full Counter can only reflect "power" attacks, and is useless against indirect attacks such as Ban's Physical Hunt, or an ordinary punch.

After Meliodas somehow wins, and is proclaimed the winner, King states that he had felt something strange during the aftermath of Ban's punch. Diane responds that she was able to see it clearly, explaining that in the midst of the resulting dust and debris from the punch, Meliodas crushed Ban's hand, then going on to defeat him; she also explains that Meliodas' eyes were colored black, and that he had a strange black colored symbol on his forehead. As Elizabeth wonders if the black colored symbol was the same one Meliodas had had during Golgius' trying to take his sword in Dalmary, Diane states that she has seen her captain having the mark once before, and that it makes her feel uneasy. Meliodas then walks towards them, and upon King questions him if he is alright, states that as soon as he defeated Ban, he regained all his abilities, leading Diane to mentally wonder as to how he was able to counter Ban's attack, before the Sin of Greed was defeated. When the next battle is declared to be between "Matrona" and Hauser, Diane hurriedly hands Meliodas a shrunken Elizabeth and the princess' pendant, before leaving for the battle. Love Helm then begins the battle. Diane mentally reminds herself to be careful, and not ruin her disguise. Hauser seems to notice something, but turning to the side, points to Diane's chest, whose chest button was undone. Love Helm comments Hauser to be a gentleman for doing so, but also states that part of the audience disapproves of his action, and wonders if Hauser, despite his looks, has a pure heart, to the Holy Knight's embarrassment. In the fighting ring, Hauser charges towards Diane, using the same technique he had used in his previous battle, to use his wind manipulation-related powers to form a small tornado around his arms, and attack with it. Diane manages to dodge it, and states that such an attack can cause great damage. Hauser agrees to it, and continues to repeatedly attack her, while stating that, if she stays still, she won't be hurt, instructing her to stop struggling against him and leave it to him, and that the attack will feel "great", and be similar to flying. Meliodas, in response to the Holy Knight's statements, comments that he is amazing for so many repeated double entendres, much to Hauser's anger, with him replying that he dislikes hurting women no matter how strong they are.

Hauser, despite not wanting to harm a woman, forms two twisters on either side of Diane, and then goes toward her to punch, but finds his attack to be easily stopped by his opponent, leading him to bewilderedly cite Diane's earlier comment that his ability was dangerous. Diane pushes him away with a single slap, and states that she had actually said so, because she had not wanted the clothes she has borrowed from Elizabeth to be torn. Hauser then states that he can finally unleash his full powers, to which Diane expresses her anger at his attacks having torn her clothes. As her skirt appears to be tearing, Hauser states that he has now become interested in Diane's powers. He then forms a large horizontal, but flat twister, warning Diane to flee or die. Much to his shock, however, she remains unharmed, leading to his confirmation that she is a Deadly Sin.

Not giving up, Hauser slams the ground with his hands, thus manipulating the air to create a gigantic twister, large enough to resemble an actual tornado; the twister covers completely the entire ring. Hauser questions Diane as to how his attack is, and adding that she would not be able to breathe properly, let along talk, due to it. Claiming that Diane will be ripped to shreds if she tries to resist the twister's centrifugal force, Hauser rejoices his victory as Diane is pulled above. In response, she uses a technique that appears to make her body much heavier. Diane then uses the increased gravitational force to attack, and thus defeat, Hauser from above. Diane is declared as the victor; Hauser acknowledges his defeat, and Diane, apologizes, explaining that she lost her self control and became serious. In response, Hauser states that he is honored to have been fought seriously by a member of the Seven Deadly Sins, and does not believe Diane's weak lies that she was merely a girl happening to pass by Byzel. He confirms her identity when King addresses her as "Diane", with her apologizing again, walking away, and then apologizing to Elizabeth for ruining her clothes.

After the fight between Cain and Meliodas, Diane immediately wanted to ask if Meliodas knows Cain, only to be stopped by King who told her to remember the seven laws of the Seven Deadly Sins. The fight between Meliodas and Diane soon begins, and Diane suggests to Meliodas for them to lightly hit each other a few times, with Meliodas finally delivering a final blow which will punch her out of the ring in a dramatic manner. However, the two of them are then interrupted by three women, who begin cheering Meliodas with a fairly erotic attitude, also implying that they have had relations with him before this incident. Ban later pays the three woman for the cheering act, in hopes of stimulated Diane's jealousy. Meliodas appears to be confused by the three women, replying to Diane's question that he does not know who the women were. Angered, she assumes that he has relations with so many women that he has completely forgotten all of them, and, viciously punches him into the ground as their battle begins.

Meliodas then gradually pulls his head out of the ground, stating that he knew that it was all part of Ban's plan. Despite him trying to calm Diane, she would not listen and continues to attack Meliodas. The two begni fighting seriously, slowing breaking apart the Great Byzel Rock. Diane then manages to land another powerful punch onto Meliodas, almost knocking him out of the ring and barely able to stop himself at the edge just in time. Meliodas begins wondering how Diane is still so strong even after shrinking, only to soon discover that she is slowly growing back to her normal size, with her clothes starting to rip apart. Meliodas attempts to warn Diane but she continues to refuse listening and focuses onto attempting to attack him. Suddenly, all four of the members of the Deadly Sins notices that the Holy Knights were approaching, and Meliodas decides to stop their battle.

The four reveal themselves the members of the Seven Deadly Sins, and begin telling the civilians to leave the town whilst threatening and frightening them. Suddenly, a shower of explosive flares begin striking Byzel, leading to everyone believing that it was an attack from the Seven Deadly Sins, when it was actually delivered by Geera.
