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, having left it 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 very confident regarding her abilities, and appears 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 Prankster Imps, after being tricked and defeated by Meliodas, retreat to a sleeping Diane, inadvertently leading the Sin of Wrath, Elizabeth and Hawk there along with them. Diane wakes immediately upon hearing the Imps' apologies for allowing a Holy Knight to go through them, since the creatures believed Meliodas to be one, and then instantly grabs Meliodas with a hand. After realizing his identity, she cuddles Meliodas, and as Elizabeth introduces herself to be traveling with him, she throws a tantrum, calling her captain a "cheater", much to Elizabeth and Hawk's bewilder. Meliodas, then calming her down, explains to her the reason he and Elizabeth were traveling together, and then informs her than he has almost no memories of the day they to meet the Great Holy Knight, much to her surprise. He begins to narrate the only memories he has, with the last events he remembers being someone apologizing to him, addressing him as "captain".

The narration leads Elizabeth to speculate the existence of a traitor in the Seven Deadly Sins, and their framing for Great Holy Knight's murder. Hearing that, Diane declares that she will help Meliodas no matter if it is a traitor or a Holy Knight, and also adds to Elizabeth that the reason she is helping them is only for Meliodas. Suddenly, they notice a gigantic thundercloud in the sky; a lightning bolt then binds all of them, and the assailant is shown to be Gilthunder. Diane and Meliodas realize their assailant to be a Holy Knight, as Elizabeth recognizes him, and introduces him as Gilthunder, a Holy Knight very close to her father. Diane watches as, Elizabeth, after Gilthunder kicks Hawk away, runs towards the talking pig, and as Gilthunder, pointing his sword at Meliodas' neck, and stating his reasons for wanting to fight the Sins, declares that he is stronger than any of them now. He offers to unbind Meliodas and Diane to fight them; before he could do so, however, both easily break his spell themselves, with Meliodas instructing Diane not to interfere in their battle. Diane then observes the Holy Knight and her captain's battle, watching worriedly when the latter is gravely slashed by the former, as the battle continues.

After Meliodas is revealed to have allowed himself be slashed, in order for Gilthunder to reveal Ban and King's whereabouts as his last wish, Diane grabs the Holy Knight, and despite him releasing lightning to escape her grip, flings him from the Forest of White Dreams. Sometime afterward, Diane is shown to have joined Meliodas, Hawk, and Elizabeth in their journey, as Meliodas decides to head first for Baste Dungeon, where Gilthunder revealed Ban to be imprisoned. Later on, she is walking with the rest of the when they decide to go free Ban from the Baste Dungeon. Elizabeth objects him, arguing that having his wound heal before heading there would be better; Diane is shown to be angry at Meliodas' perverted actions toward the princess. Though he affirms that the wound was not major, Elizabeth quickly discovers that he has collapsed.

When Elizabeth asks for Meliodas to go with Cenette, Diane says that she will watch Elizabeth. Later that night, Diane is outside the building when they have a party on the roof. Ban then says that its nice to she her, which Diane says that it would be fine if she hadn't seen him for a hundred years. During the party, Diane has eaten Meliodas by accident when he tries to feed her an apple. Later, Diane tells Elizabeth that she will fight for her since Elizabeth was really cool today. Diane then tells Elizabeth that she does have a power and that is to move the heart of the captain and her. Diane then asks if he can call her Elizabeth which Elizabeth says yes to.

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.

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.

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.

Ongoing Arc
Diane and the other sins went to a town close bye called Byzel which hold a festival every year and they are news of a "weapon that no one can use" thinking it could be a sacred treasure they went there. When Meliodas and the other are about to left, Diane was upset and start smashing the ground due to being bored and left all by herself, Meliodas told her that since she is a giant and the wanted poster is correct and might bring attention. King offer to stay with Diane but Elizabeth decided to stay with her and have some girl talk which she is happy to do.

As Matrona
Matrona is first seen during the beginning 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 Matrona, 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. Matrona 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, something that enrages Matrona. 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, Matrona 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, Matrona replies that "she" is right there, with an expression of Elizabeth's.

When King get closer to Diane, he notice a tiny Elizabeth came out of Diane bosom which shock and embarrassed him. Diane and Elizabeth explain to the Sins when they left, Elizabeth and Diane head into the forest to find ingredients for dinner, where the princess finds a Chicken-Matango. Diane, considering it an ingredient, tries to grab it, but the creature, realizing itself to be in danger, releases spores that shrink both of them.

Meliodas ask her why she didn't say anything to which she said she wanted to surprised Meliodas and jump on him happily to King shock. Diane then said he can grope all over like he does with Elizabeth but Meliodas doesn't want to which made Diane upset. Diane ask what he see in herself and started to think because she was big, Meliodas doesn't care about her but Meliodas rub Diane head and told her he doesn't do that to someone important to him which made Diane happy.

Diane then remember something important which Meliodas ask what is it which Diane reveal that they can have kids now to which Diane didn't learn anything. During King fight, Diane told King he can do it which give her his game face. Diane ask Meliodas if King is strong without his weapon to which reveal that King is very weak and lost the fight.
