Guila/Plot

Capital of the Dead arc
Guila tracks down the Sins to a small village said to be the gateway to the Capital of the Dead. Once there, and after seeing Meliodas and the others enter the place, she interrogates Ellen and her brother for information on how to do the same, and is told that "a priceless memory shared with the deceased will open the path". Still, uncertain on the specifics of entry, she decides killing herself to be the quickest means of reaching the Capital of the Dead and without hesitation, pierces her heart.

Appearing before Meliodas, Diane, Elizabeth, and Hawk in the Capital of the Dead, the group wonders how she entered, to which Guila explains that she died to gain entrance and greets Meliodas and Diane, introducing herself as a Holy Knight. Drawing her rapier, Meliodas instructs Elizabeth and Hawk to escape. Guila launches an attack that and sends the two Sins flying, and comments that the capabilities of the Giant Clan and Diane's ability, "Creation", are not very impressive. As a response, Diane demonstrates her abilities and manages to trap Guila, though the Holy Knight easily frees herself with a blast from the tip of her rapier. She forces Diane back with another explosion and dodges Meliodas' rapid succession of attacks, while complimenting Meliodas' skill, and questioning why he doesn't use his sword before attacking with a quick thrust of her rapier. Meliodas counters Guila's attack and reflects it back at her. However, Guila is revealed to be unharmed and explains that she was aware of Meliodas' "Full Counter" ability, then requesting that the two Sins satisfy her.

Though both Meliodas and Diane launch a barrage of attacks against her, Guila easily overwhelms them with her ability, "Explosion". Before she is able to deliver a devastating blow, however, she is stopped by Ban. She asks that Ban release her rapier, and reveals the name of his ability, "Snatch", proceeding to explain that its details aren't well-known to the kingdom. The Holy Knight then fires a "Drift Bomb" at Ban, whose explosion forces the Fox's Sin to release her rapier. Meliodas quickly attacks while her guard is down, only for her to dodge all his strikes and counter with a smokescreen generated with a snap of her fingers before striking him in the back with another explosion. With Ban recovered, she comments on his immortality, then telling him it is different from invincibility and that no matter how many times he regenerates, he will be turned into sliced meat before her.

Guila then launches an attack on all three Sins at once, seemingly overpowering them with relative ease. While managing to wound Diane, she is attacked by Meliodas and Ban, though effortlessly knocks Meliodas away and slices off Ban's arm. Stabbing Ban though the throat, she is caught off guard by King, who thrusts his spear through Ban's torso, sending her crashing into one of the many crystals that dot the Capital of the Dead. Guila comments that King's betrayal, though unfortunate, was expected, to which King responds that he never had any intention to ally with them, and asks her to relay a message to Gilthunder, whom he calls her superior. Insulted at the notion that the Gilthunder is her superior, Guila tells King to save his jokes for sleep-talking and fires explosive "Shot Bombs" at him. King, however, easily counters her attack, which leads her to compliment his power and his capacity to use it in conjunction with his sacred treasure, the Spirit Spear, Chastiefol. She requests that all four of them attack her at once, but King replies that he will fight her alone.

Guila readies herself to fight King, but, much to her surprise, finds her cheek cut by King's spear before she has time to react. A barrage of continuous strikes rain down upon her as she rapidly dodges and defends King's relentless attack. Overwhelmed by the speed and accuracy of King's spear, she flees to higher ground and deflects King's spear with an explosion. Raising her rapier skyward, she activates her attack "Brilliant Detonation", but is overcome when King multiples Chastiefol into numerous smaller spears that swiftly pierce her from behind, destroying the crystal she is standing on and burying her under it is debris.

Though severely injured, she rises from the debris and attacks an unguarded King, stating that even if he defends himself, he wouldn't come out unscathed if he is attacked at close range. Just before her attack reaches, Meliodas repels it back at her, the force of the explosion having sent her soul back to the living world. Meliodas' group encounters her unconscious body once they have also returned and contemplate what they should do with her, with Meliodas commenting that they should leave it to him. Sometime later she is found by Helbram tied to a tree, with a new haircut and her face written and drawn on, much to the amusement of her master.

Vaizel Fight Festival arc
Guila, and her master Helbram, are ordered by their superior, Hendrickson, to bring Twigo and Jericho to the unrevealed place where the corpse of the demon is chained and kept. Both of them then watch as the Great Holy Knight informs the two apprentices about the demon's blood's power-enhancing qualities, and references Guila as an example to said qualities. While the two hesitated, Guila reminds them that since they are now aware of the Demon, they would not be allowed to leave. After both of them drink the fluid, Twigo gradually explodes due to being incompatible with the blood. On the other hand, Jericho suffers immense pain but survives the occasion. Later, Jericho and Guila, along with another armored Holy Knight, are shown to be riding two huge ray-like creatures. Wielding new weapons and adorning new armor, they head towards Vaizel. The three soon arrive at Vaizel, interrupting the Fight Festival, and making an entrance by delivering a subtle shower of explosive flares.

Guila, soon after, finds Meliodas. After a short greeting, Guila, pointing her lance towards him, releases several flares, which stop midway. When Meliodas jumps to destroy one of them, it suddenly explodes, triggering multiple explosions, that together result in a gigantic explosion. As he collapses, Guila thanks him for cutting her hair while adding make-up on her earlier, stating that the person most important to her complimented it, referring to Zeal. After Jericho also defeats Ban, both state their main foe still remains. Few moments later, King appears from behind. Guila and Jericho immediately and relentlessly attack him, but are easily stopped by King using Chastiefol's different forms. After some time, as King yawns and states that he has warmed up, Guila and Jericho are shown to be defeated and collapsed. After defeating the two, King, deducing that the attack on him was to divert the Sins from the Holy Knight's actual goal, interrogates as to what it is. He then declares that the Sins will win; Guila retorts back, declaring that the contrary.

Not long after, both stand up again, ready to fight King. They again attack King relentlessly, but are again stopped with ease by King using Chastiefol's "Sunflower" form. When King releases them with several projectiles from "Sunflower", Jericho and Guila resign to their fate, realizing that they cannot defeat King. That instant, Helbram, who has been under the disguise of "Love Helm", vertically cuts Chastiefol into two, and rescues his subordinates. Helbram stays behind to fight King, which prompts Guila and Jericho to immediately state their readiness to support him. He instead instructs them to recover the target: Meliodas and his sword. Jericho and Guila soon arrive at the other battlefield, where Guila, noticing that the targets have already been captured, then extends her hand to help Elizabeth after Griamore releases his barrier over the princess, replying that her duty also included a princess' protection when Veronica states that she will be taking Elizabeth. When Veronica retorts that she also has Griamore, Hawk attempts to stop Guila. The Holy Knight, after attacking him with her lance, points the weapon towards Veronica.

She, dismissing Veronica's authority, orders her to hand Elizabeth over, which leads Griamore to surrounds her and Jericho in a barrier for their insolence. Guila's attempt to break it backfires when she is damaged by her own explosion. After Elizabeth manages to flee while Griamore and Veronica's attention is focused on her, Guila offers to help. When Griamore refuses, she reveals that her orders were to retrieve the princess, dead or alive, and that she had planted explosive mines around Vaizel, as one of those explodes, and fatally injures Veronica, who was chasing Elizabeth. The barrier then break due to Griamore saddest over Veronica death. Griamore tearfully and angrily turns to attack Guila, but is defeated with one attack from behind.

Jericho states her worries about injuring the son of a Great Holy Knight, and comments on Guila's insane nature when she suggests to merely report that the Deadly Sins killed Veronica and Griamore. As Guila walks towards Elizabeth and asks her to come with them, a collapsed Griamore angrily questions them as to Hendrickson's goal. Immediately as Guila replies that it is the resurrection of the Demon Clan, Ban, despite heavily injured, attacks Jericho, stating that he cannot take a nap after hearing that. Guila then captures Elizabeth, who, hugging Veronica's body, tearfully pleads for Meliodas to rescue her. As Guila tries to calm her, saying that Meliodas would not be rescuing her now, and Elizabeth once again cries his name, the Goddess Amber, inside which Meliodas is sealed, begins to darken, and then shatters, releasing a black colored substance, quickly forcing Guila to step back. It was then reveal to be Meliodas with half of his body cover in black mark, Guila wonders, while holding Meliodas' sword as to how is alive, only to find her hand cut before she could even notice any movement. As Hawk, shocked, gapes, Meliodas, completely emotionless, is holding Guila's cut hand, which is still grabbing his sword.

When Guila scream in pain for losing her hand, Meliodas then swing his sword lightly and knock both Guila and Jericho. Jericho then healed Guila by using an Incantation Orb which restore her hand as well, but both Guila and Jericho were then easily defeated by Meliodas. Guila and Jericho were later been saved by Helbram during Diane furious attack and possible were taken back to the kingdom.

Jericho mentions that she saw the Seven Deadly Sins battling and defeating the Armor Giant, and she sensed the powers of a Holy Knight and a demon within the monster.

Suddenly, the Holy Knights sense a subtle quake occurring underground and eventually discovers Diane. The Holy Knights begin attacking Diane, with Dreyfus finally sending her flying away to a nearby city with his technique Pulverize. Realizing that her brother, Zeal is also in the city, Guila quickly departs to find him. During her search, she watches Helbram begin destroying buildings to frame Diane as the villain. Guila asks Helbram for an explanation, to which he replied by saying that the Holy Knights need a villain to become heroes themselves. Jericho tells Guila to ignore the petty details and should go after Diane's head, when Guila questions her if she remembered why she drank the Demon's blood.

Howzer was surprised to see Gowther without his armor and fought against Dreyfus inside his mind. When Dreyfus broke free of Gowther Invasion, Guila was shock to see Gowther lost, but Howzer point out that thanks to him, Dreyfus left due to mental injury and Gilthunder took him away, leaving Helbram alone. Howzer try to attack Helbram until he summons Call of Inferno which was death smoke that was killing them. Diane stood up again to smash Helbram from using Inferno. Diane gave Zeal to Guila and told them to leave, but Howzer refuse and told her she should worry about herself than others. Helbram stood up again to use Killer Iceberg on Diane which put her to near-death state. Before finishing her off, King appears to save Diane.

Afterwards, Guila is carrying an injured Jericho and asks Zeal if he is able to move, at which he confirms with a nod. Guila, along with Jericho and Zeal, decides to have a truce with the Deadly Sins and head out to save Elizabeth from Hendrickson.

What's up with that girly outfit of yours!?". Guila replies,"Well, I am a girl. You look cute yourself, Jericho." Jericho then admits that she is jealous of the fact that Guila could keep her powers. Guila then explains that the reason she still has her Holy-Knight powers are the all because of the power of her 'love' and signals behind her. Jericho confusedly looks over Guila's shoulder and, in surprise and horror, spots Gowther through the window.

Guila is later seen spending time with Gowther at the Boar Hat during the festival. Strangely, her younger brother Zeal is also shown during the festival alone at their dinner table, empty plates surrounding him and looking depressed. This seems to suggest that she abandoned Zeal to spend time with Gowther, contradicting her former devotion to her brother. This is later revealed to have been due to Gowther's brainwashing of her as he became interested in learning the feeling of love rather than friendship and as a result brainwashed both her and her brother by manipulating their memories, including making fake ones and showing real ones to have Guila be his lover to show him the feeling of love.

After discovering it, Diane enters in conflict with Gowther demanding to repair the memories of both. There, Gowther uses his Blackout to put almost the whole kingdom unconscious, including Guila and Zeal.
