Jericho/Plot

Baste Dungeon arc
As Ban escapes from his cell after hearing that his captain was still alive, from the guards, Jericho investigates the disturbance, soon finding the Deadly Sin. Showing only slight irritation, she demands he quickly return to his cell. Unimpressed by her arrogance, Ban, calling her a "brat", tells her to watch her attitude "when talking to a hero". Jericho retorts, calling him a "half-dead criminal" and instructs the guards to report to "Lord" Golgius that a prisoner had attempted to escape and that she had no choice but to kill him. She then attacks Ban without warning, launching a flurry of slashes, but is shocked to find that not one of her attacks managed to strike Ban. She wonders how he was able to dodge her attacks despite his severe wounds, only to realize that they had all healed. Ban then shows her a scar on his neck, stating that only that wound was a real wound, and that it was a special case.

Defeated and disrobed by Ban in order to get an armor and clothes, an embarrassed and angered Jericho orders the guards to search for Ban as well as bring her a change of clothes and armor. Later, after getting a new set of clothes and armor, she leaves the dungeon along with the rest of the guards before Meliodas and Diane go in. She asks Golgius, who was with her, what his orders are, and is surprised when the Holy Knight triggers the Eternal Seal Spell and says that even ten Tyrant Dragons couldn't break the spell. She is later shown to be astonished when Baste Dungeon is destroyed.

Vaizel Fight Festival arc
Jericho, along with Twigo, is later summoned by the Great Holy Knight, Hendrickson, who states that he will give them new powers, after which both are guided by Guila and her master, Helbram to a mysterious location with their faces covered. There, the both are shown the corpse of a chained demon, with them being surprised to know that a demon was not just an object of folklore, but actually existed. They are then given its blood to drink, and are explained to about its power-enhancing qualities by the Great Holy Knight. Jericho, though being hesitant at first, drinks it after remembering her embarrassment at Ban's hands. While Twigo dies due to being incompatible with the blood, she is shown to be compatible to it, and survives, thus gaining new powers, and is welcomed by Guila.

Later, Jericho, Guila, and Marmas are shown to be riding two huge ray-like creatures with new armors and weapons. As they travel to Vaizel, Jericho expresses anxiousness to use her new powers. The three soon arrive at Vaizel, interrupting the Fight Festival. Noticing their arrival, the four Deadly Sins separate. Jericho soon finds Ban and delivers a surprise attack. She states eagerness to obtain her revenge, and that she will make sure Ban remembers her name. Her subsequent re-introduction reminds Ban of her, with him questioning her whether or not she cross dresses, since he believed that she was a male from their previous encounter. Much to Ban's surprise, the wound received from the surprise attack doesn't heal instantly, and Jericho attacks him again. She adds in that she no longer has any reason to pretend to be a man since she was weak, but is not so now. Kicking Ban, she spreads a drop of his blood that spurts near her lips as a substitute for lipstick. A few moments after Guila defeats Meliodas, King appears behind the two Holy Knights.

Guila and Jericho immediately and relentlessly attack him, but are easily stopped by King using his Chastiefol. After some time, Guila and Jericho are shown to be defeated and collapsed, and King mocks them. Not long after, both stand up, once again ready to fight King. They redouble their efforts in attacking King, 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. In that instant, Helbram (who has been under the disguise of "Love Helm") vertically cuts Chastiefol into two, and rescues his subordinates. He stays behind to fight King, which prompts Guila and Jericho to immediately state their readiness to support him. Instead, they are instructed to recover the target Meliodas and his sword. Jericho and Guila soon arrive at the other battlefield, with Jericho making an entrance by slashing Ban from behind, and allowing Veronica to escape from him. Noticing that their targets have been captured, Guila then also orders for Veronica to hand Elizabeth over. Griamore, unable to witness such insolence, quickly surrounds her and Jericho in a barrier. Guila's attempt of breaking through back fires, as the barrier does not waver, and her explosion instead harms her and Jericho. Jericho then watches without surprise when Elizabeth is trying to flee with Veronica in pursuit. This triggers Guila's explosive mines, and fatally injures the older sister. After Veronica dies, Griamore's emotions make his ability unstable, and the barrier surrounding Jericho and Guila vanishes.

Guila then heavily injures Griamore, and Jericho states her worries about injuring the son of a Great Holy Knight, and comments on Guila's insane nature. Guila dismisses her worries. In reply to Griamore's question, Guila informs him that Hendrickson's goal is the resurrection of the Demon Clan, which prompts Ban to attack Jericho. While the two battle, the Goddess Amber shatters, releasing a black substance that forms Meliodas, much to the surprise of everyone present. After Meliodas swings his sword at Guila and Jericho, Jericho rushes toward a gravely injured and dying Guila and uses an Incantation Orb to heal Guila. Ban sneaks up behind them and takes some of them. When Jericho was about to fight Ban, Ban tells them both to look behind them, but Meliodas defeats them with ease. Guila and Jericho were later been saved by Helbram during Diane's furious attack and possibly were taken back to the kingdom.

Armor Giant arc
After returning to the Kingdom of Liones, Jericho witnesses a knight reporting to Helbram of an Armor Giant being sighted at Ordan. Helbram gives the order to send Dawn Roar after its head, and this causes Jericho to grow skeptical. She then decides to tail after the dangerous group of knights. Being quiet, she witnesses the battles between Dawn Roar, the Armored Giant, and the Deadly Sins. After Dawn Roar leaves the battlefield having received the Armor Giant's head from Gowther, she eavesdrops on their conversation.

Kingdom Infiltration arc
Jericho is sparring with Guila when her uneasiness prompted the two to stop. Being questioned by Guila, Jericho reveals that she tailed the Dawn Roar to see why Helbram had not ordered the New Generation to deal with the Armored Giant. 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-which greatly disturbed her. She gives Guila a necklace that she retrieved from the grave of the Armored Giant created by the Deadly Sins, and notices her shock when she sees the item. When the three of the Deadly Sins-Meliodas, Ban and Gowther-begin infiltrating Liones, she is ordered by Dreyfus and Helbram to stop them along with Guila, Howzer, and Gilthunder. When the two join up with Howzer and Gilthunder, Jericho begins quarreling with Howzer, but soon calms down when Dreyfus begins questioning Helbram. Soon after entering Hendrickson's magical research building, the Holy Knights sense a subtle quake occurring underground and eventually discover Diane. Jericho immediately rushes in to slay Diane with Godspeed: Bone Crusher, but is easily blasted away by Gideon. Gilthunder catches her by the leg, explaining that the Deadly Sins are far too powerful for them with their Sacred Treasures.

Jericho is amazed as Dreyfus overpowers Diane and sends her flying with Pulverize. When Helbram begins framing Diane for the damaged buildings in the city, Guila yells at him for being unjust, leading Jericho to tell her to not worry about such petty details. Agitated, Guila asks Jericho whether she remembered her reason for drinking the demon blood. As the Holy Knights prepare to kill Diane, Howzer and Guila decide to step in to protect her. Jericho tries to bring Guila back to their side but is rejected. As the Great Holy Knight Dreyfus brands Guila and Howzer traitors, Jericho reluctantly raises her weapon to battle her former partner. Just as the Holy Knights make their move, Jericho and the others were caught and sent into the air by Howzer's Rising Tornado. Inside the twister, Jericho pleads for Guila to stop, but the latter apologizes as the rogue Holy Knight fires Shot Bombs into the twister, severely injuring Jericho in the process. After Gilthunder manages to interrupt Guila's and Howzer's Combined Technique: Bomb Cyclone, Jericho and the others were freed. Due to all the injuries she received from the combined technique, Jericho falls into the ground with her skirt burned off, and loses consciousness.

Helbram, after casting off his human form, attempts to kill Diane and the others with the Sacred Tree roots. A still-unconscious Jericho would have died from the mad fairy's attack until King used Chastiefol's Form Eight Pollen Garden to protect them, saving her life again. Jericho remains unconscious until the Deadly Sins and Holy Knight set Bartra Liones free and put Dreyfus in jail for his crime. Jericho was displeased with the current situation as she wanted to defeat the Deadly Sins and demands Guila to tell her reason for taking the demon blood. Guila reveals that she wanted to protect her brother, but lost her human heart along the way. Jericho then in turn reveals that she only cares about proving her brother wrong about women being Holy Knights. When Hendrickson comes and destroys the castle, the latter uses Blood Awaken to turn the New Generation into Demon hybrids, and Guila and Jericho are trying to fight back.

Jericho transforms into a Demon hybrid and tries to attack Zeal and Guila. However, Gowther appears and uses Invasion on her while Diane is holding her back with what strength she has left. As Diane is fighting off Jericho, she overhears Jericho saying that she wants to be stronger than her brother. This makes Diane believe that Jericho is still alive inside of the monster, but doesn't know what to do. Jericho's Demon form continues to bear down and tackles Diane but is halted when Ban throws Gilthunder at her face. This temporarily knocks her down. Not soon after, Gustaf (who has recovered from Helbram's defeat) searches for her as she asks her brother if he finally acknowledges her now. She ends up crushing Gustaf apparently to the death. Within the Demon form, Jericho was horrified of her actions and pleads for someone to kill her now as her other side gloated victory, raising Gustaf's body like a trophy. As Jericho was about to devour Gustaf, Gilthunder saved him from his fate while Ban goes to confront Jericho. Gustaf begged him not to kill her while Jericho pleads to die as she doesn't want to live as a monster. Ban grins as he said he will end her life. He uses his three section staff to strike her. But, instead of killing her, Ban removes a strange "plant" which he destroys. Jericho returns to normal while Ban said he ended her life as a Holy Knight, saying that she shouldn't hold it against him.

Post-Kingdom Infiltration arc
After Hendrickson's defeat, Jericho (in her new clothes) storms out of a house furious while Gustaf insists that she help rebuild Liones. She refuses as she is unable to accept having lost all of her powers after Ban removed the strange plant within her body. (If he did not remove it, she would have remained as a demon.) She quickly blushes at the thought of a topless Ban holding her in his arms whilst half naked. Still upset, she encounters Guila who she notices is dressed femininely and beautifully. Jericho immediately admits that she is jealous that Guila is able to keep her powers, despite most of the New Generation Holy Knights having lost theirs. Guila reveals that she still has her powers because of love, confusing Jericho until she notices Gowther waving to them whilst grinning with a sinister look.

Albion arc
After the National Foundation Festival, Jericho, who is donned in her old attire and wielding a new sword, follows Ban and King. They had already sensed her presence but let her come along in their journey to the Fairy King's Forest. In their traveling, Jericho tries to hide her feelings towards Ban by acting tough and angry for what the Fox's Sin of Greed did to her in their first meeting. She also doubts King's title as the Fairy King due to her disbelief in the Fairy Clans and the Forest's existence until they stumble upon the slowly-restored Fairy King's Forest.

Jericho then sees three Fairies reappearing and squeals in excitement. The former Holy Knight was shocked to learn that Ban was named as the new Fairy King after the Fairies rejected King and praised the former for saving the forest. As they venture further into the new Fairy King's Forest, Jericho witnesses Fairies (and Prankster Imps) appearing all over the forest and sees Elaine's well-preserved corpse while wondering if she's also a Fairy like King. Jericho also sees the Fairies ganging up on King under accusations of treason, which were all nonsensical. Oslo steps in and defends him. Later, King asks Jericho when she is planning to leave as only a few select humans are allowed to be in the forest. Jericho replies that wherever Ban goes, she well. Ban reveals that he was not going back to the Boar Hat, as he was planning on going on a journey to find a way to bring Elaine back to life. Jericho offers to come along as his disciple as she owes him a debt, and he refuses.

When an Albion appears and begins to destroy the forest, Jericho goes with Puora to find Ban. Upon arriving at the Sacred Tree, they discover the entrance block with roots product of the magic of Gerheade. Jericho uses her sword to cut the roots and discovers Ban incapacitated by Gerheade.

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 are 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.

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 to 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.

Jericho rushes over to see if the fairy is ok as Ban begs Elaine to hold on. As the two worry over the Fairy, Melascula and Galand arrive at the scene. Melascula 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. During the fight, Ban's soul is taken out of his body by Melascula to be consumed and is soon consumed by Galand, much to Elaine and Jericho's grief. Lamenting before the soulless body of Ban, Jericho intends to take revenge by facing the demons. It is soon revealed Ban's soul made it back to his body and then snatched both one of Galand and Melascula's hearts. Ban then grabs Jericho and Elaine, and retreats while the demons are temporarily injured. After traveling a few miles, Ban collapses due to exhaustion and explains that he was saved by Zhivago, who appeared before Galand and was eaten in Ban's place. After asking Jericho to take Elaine and run, she refuses and instead, she promises to carry them to safety.

As Jericho carries Ban and Elaine away, Galand and Melascula start toying with them by throwing boulders towards their location. They miss twice, before the third one hits the ground and sends the group tumbling off a cliff. Thanks to Elaine, the three of them land safely near a dark cave but also apologizes to the Holy Knight Apprentice for her actions earlier. Inside the cave is an open bar with a lone bartender inside. As they enter, the bartender greets them and welcomes 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.

As Galand and Melascula 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 Galand's deathmatch.

With Elaine in Ban's arms, he asks if she's ok, and she responds that she is feeling better than she used to feel, and is too happy that she thinks she'll die again to which Ban tells her not to think like that. Jericho interrupts the conversation by agreeing with Ban and explains that Melascula explained she brings the dead back by their connections with the living and their regrets so as long as Ban and Elaine's connection stays strong, Elaine will be ok. 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 as he sees Elaine before him, as she happily calls his name.

When Gowther reproaches Jericho that in the past she sacrificed her own humanity to gain power, Jericho claims that it was a mistake because she wound up hurting her brother and innocent people. Jericho tells him that the bonds between people allow them to understand each other, this motivates Gowther more to get a heart. Annoyed, Jericho tries to attack him but Gowther quickly kicks her out. Upon awakening and seeing as Escanor launches a powerful attack that leaves Drole and Gloxinia incapacitated, Jericho points it out to Gowther and praises Escanor, asking him how to achieve such a thing when it was still night.
