Vaizel

Byzel (バイゼル) is a merchant town in Britannia that is famous for its annual flea market festival. Giants are disallowed entry into the town since they had made a "huge ruckus" a few years ago. Byzel is also host to an annual fighting tournament which takes place on top of the Great Byzel Rock, during the flea market.

Background
Literally everything is said to be sold in the town's annual flea market festival, including junk, weapons and jewellery; apparently, it once even had a crown from a distant kingdom. The Deadly Sin, Diane's sacred treasure, Gideon, also found its way to the flea market after she lost it, becoming popular as a "weapon that no one can use".

Plot
Meliodas, Ban, King, and Hawk travel to Byzel after hearing rumors of a "weapon no one can use", suspecting it to be a sacred treasure. There, a drunk elderly man directs them to the annual fighting tournament, whose reward is the aforementioned weapon, which is considered a giant's normal war hammer, but is actually Diane's sacred treasure, Gideon. Meliodas and Ban, both being very eager to enter the tournament and fight each other, immediately enter, with the former dragging King along with the two despite him not wanting to join the "savage" tournament. A three-time champion, and a mountain bandit turned merchant, Taizoo, stops Meliodas, believing him to be an ordinary child and to be lessening the quality of the fight festival. However, the Holy Knight, Hauser, who is also revealed to have joined the festival, stops Taizoo, stating that age shouldn't matter in a festival. The tournament is also entered into by a mysterious girl.

While the preliminaries begin Hawk is seen selling ale from the Boar Hat to the audience, as Meliodas instructs Ban not to use his full power and kill opponents, and manages to make King willing to fight by telling him that Diane would be happy if her sacred treasure is gotten back. The referee of the tournament, Love Helm, then informs the fighters as to the rules: knocking fighters off the ring will disqualify them, the final eight contestants remaining will advance to the next round, and anything is allowed as long as it involves bare hands. During the preliminaries, a handful of exceptional fighters easily defeat all the other ones, who, after the battle ends, are shown to be the ones who have survived and have advanced. After the drawing of the lots that will determine the match-ups in the first round, the first battle is assigned to be between Matrona, the mysterious girl, and the Holy Knight, Griamor, who is unarmored. The second fight is between Hauser and Taizoo, with the mentioning of Hauser's name leading King to realize the man's identity as a Holy Knight. The third battle is revealed to be between Cain, the elderly drunk man who had lead Meliodas and the others to the tournament, and King, whom Ban had entered under the name, "Old Fart", much to his irritation. Finally, the last fight is among the remaining two contestants, Ban and Meliodas, whom the former has entered under the names, "Baan" and "Meliodaz". This causes Hauser to almost recognize both of them from their physical traits, but dismiss them as the Deadly Sins because of their obvious name changes, due to his naivety. As the first battle begins, Veronica is seen standing among the audience and commenting that the Seven Deadly Sins have fallen for the trap, with Matrona then being asked by the referee to remove the cape she had been wearing, thus revealing her incredible resemblance 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. Matrona, as the battle begins, immediately attacks Griamor relentlessly. Her attacks are, however, negated by the Holy Knight's ability, "Wall", and she struggles with its omnidirectional expansion. When Griamor states that he will humiliate Meliodas next, however, Matrona, enraged, declares that she will not let that happen, destroys the barrier, and then, with the same punch, punches Griamor in the neck, sending him flying out of the ring, surprising both Veronica and Hauser, and causing her 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. 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 that, after he and the others had left for Byzel, she and Elizabeth had headed into the forest for gathering ingredients for dinner. There, Elizabeth found a strange creature, that, when Diane tries to grab it, somehow shrunk them, Diane having shrunk to the size of a normal human, and Elizabeth, to a size small enough so that she is able to fit inside Diane's bosom. Diane has borrowed Elizabeth's clothes, and is also wearing the princess' jewelry, since they do not want the latter 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, an ability that is the most potent and unique of the abilities possessed by all the other mushroom-like 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, and Elizabeth appears dejected. To Meliodas' annoyance, however, she then immediately huge him, while merrily declaring that they could now have children together; her hug buries his face into her chest, where Elizabeth tries to hide inside Diane's clothes.

Ban then informs King that his battle will begin soon, and finding his nose to be bleeding severely, asks him whether he is dead. Soon after, during Hauser and Taizoo's battle, Ban informs the others, who had not been paying attention to the battle, that Taizoo is losing heavily but continuing to fight due to his ego, despite his opponent now having used even a tiny bit of his power, knowing that if he uses too much of it, he would kill Taizoo. Hauser is then shown to be requesting Taizoo to surrender. When his opponent refuses to give up, Hauser, uses his yet unnamed abilities to defeat him, his abilities earning Ban and Meliodas' compliments. Soon, Love Helm announces the next battle to be between Cain and "Old Fart", the name Ban had entered King into the tournament with. King hands Meliodas his sacred treasure, and then hesitantly enters the ring; a cheer from Diane, however, immediately encourages him. As the commentator speculates on the power both King and Cain might be hiding, both having not participated actively in the preliminaries, Hauser is shown to be walking toward and greeting the injured Griamor and Veronica, and questioning them for the reason they had come to the tournament. As the fight begins, Meliodas comments to Diane that King's method of fighting barehanded was "incredible", and King mentally dedicates his victory to the giant. However, both his and his opponents' physical capabilities are soon revealed to be very low. To this, Meliodas adds upon his earlier comment, saying that King had even once lost to his cat. When King then starts using his ability, "Disaster", Cain, immediately alarmed, punches the Deadly Sin out of the ring, stating that he was so surprised, he lost control of himself, as King expresses his upset at losing, and states that he had used his ability to trigger Cain's rheumatism. Love Helm, finally, announces the final battle of the first round, Meliodaz vs. Baan. The referee, noticing Meliodas' sword, stops him, and reminds him of no weapons being allowed, but upon being told that the sword was broken and was only decorative, allows its use. Meanwhile, Hauser is informed by Griamor and Veronica that the young man he had met, and suspected to be Meliodas previously, was, in fact, the Deadly Sin himself, much to the Holy Knight's surprise. Meliodas and Ban then ready themselves for their battle.

After being informed that the two Deadly Sins are among the participants, Hauser questions Veronica and Griamor whether the two were planning to capture the criminals alone. The princess answers that their primary objective was to ensure Elizabeth's safety, and then commands Hauser to not cause a commotion and endanger it. He, however, immediately starts running toward the fighting tournament, and, much to their chagrin, instructs them back to not ruin the tournament, and rejoices him being able to witness the legendary criminals' battle personally. Meliodas and Ban's weight and height are announced, as Diane and King cheer for the fighters, and Elizabeth seems reluctant to do so. As Love Helm begins the battle, Ban questions Meliodas whether he is so excited for the battle, when his captain replies that "it" was as big then. Meliodas explains, saying that the rule of a fighter being disqualified if they are pushed out of a ring reminded him of an event long ago, and then telling Ban that he will remember it soon, punches him in the face, reminding Ban of the event that has been mentioned: the episode that led to Ban's joining of Meliodas. In the present, Ban seems to have been pushed out of the ring, but regains his balance and exchanges several attacks with Meliodas. As their battle continues, Meliodas punches Ban in the stomach, and sends him flying, but finds himself to then fall down to his knees. Immediately, Ban gets up and continues the battle, to which Meliodas flings a punch, but apparently seems to have weakened. Meliodas seems to be weakening more and more as the fight continues, leading Diane to wonder the reason for that. Answering her question, King explains that Ban's ability, Snatch, enables him to "rob" not only 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.

As the battle continues in Ban's favor, Meliodas smashes him repeatedly, only for his raw strength to be stolen during the attack. Ban, in a state of ecstasy, punches Meliodas, but despite having stolen Meliodas' strength, is pushed back by his counter. He then states that since the battle would not end by stealing in small doses, he will now rob all of Meliodas' abilities. As Ban steals Meliodas' abilities while being attacked with a barrage of punches, King states that the battle depends on who finishes their attacks first In the end, as all of Meliodas' abilities are shown to have been stolen before he is able to defeat Ban. As Ban stands over Meliodas, Diane, from the audience, yells at him to not further harm him. The Sin of Wrath refuses to give up, and states that he will win. Ban readies the final blow, and Love Helm replies to the villagers asking him to stop the battle, that if the contestant is not out of the ring, and refuses to give, the match can't be stopped. As Elizabeth pleads to Diane and King to stop the battle, 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. Despite Elizabeth's pleading, Ban punches Meliodas. When the dust and debris from the attack settle, Meliodas is then shown to be the only one inside the ring, with him then notifying the audience about their exchange having resulted in Ban crashing in a building far away, and essentially, being pushed out of the ring. After Meliodas 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 talks 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. The next battle is declared to be between Matrona and Hauser, Matrona being the name Diane has used to enter into the Fight Festival. Diane hurriedly hands Meliodas a shrunken Elizabeth and the princess' pendant, before leaving for the battle; the Sin of Wrath smirks pervertedly at the sight of a shrunken and naked Elizabeth.

Hawk walks through the crowd surrounding Ban, who has crashed into a building following his defeat at Meliodas' hands, and is lamenting at his defeat, having forgotten about what he calls, his captain's "trump card". As Hawk unwittingly carries Ban due to him feeling his body to be very heavy after using "Physical Hunt", the talking pig states that he smells a storm brewing. In the fighting ring, Diane turns back at a cheer, and upon finding Meliodas teasing the shrunken and naked Elizabeth, is angered at him not cheering for her; Meliodas continues teasing the princess as the latter does cheer for the fighter. Meliodas then questions Elizabeth as to what was wrong, to which she states the reason she has been dejected for some time: she believes that the reason Meliodas behaves this way towards her is that he doesn't consider her to be important to him.

The Deadly Sin, however, does not hear her response over the other noises, leading her to add that she was just talking to herself, and mentally state that no matter what Meliodas thinks of her, she has resolved to believe in him. She proceeds to then tell him that she was very worried about him during his fight against Ban; he replies that he will not battle like that again, but mentally adds that he will only do so when she is nearby. Love Helm then begins the battle, as Diane mentally reminds herself to be careful, and not ruin her disguise. Hauser seems to notice something, but turns to the side, and points to Diane's chest, notifying her than her chest button was undone. Love Helm comments whether Hauser, actually has a pure heart, to the Holy Knight's embarrassment. Somewhere nearby, Taizoo, upon waking from his unconsciousness, discovers Cain to have carried him from the area where he landed following his defeat. Cain commends Taizoo for putting up a good fight, but the former mountain bandit retorts that it was certainly not so, and he had, from the beginning, known of the difference in his and Hauser's strengths, and of his opponent being a Holy Knight. In the fighting ring, Hauser charges towards Diane, using his wind manipulation-related powers to attack with a small tornado around his arms. Diane manages to dodge it, with Hauser continuing to repeatedly attack her, while stating that, if she stays still, she won't be hurt, instructing her to stop struggling and leave it to him, and that the attack will feel "great", and be similar to flying. Meliodas comically comments Hauser to be amazing for repeated double entendres, much to Hauser's chagrin, him replying that he dislikes hurting women no matter how strong they are.

As Love Helm comments that Diane can only defend herself against Hauser's attacks, Taizoo commends her for doing even that, adds that if she is caught within the twisters even a bit, she will be defeated, and also that Hauser's attack was not something an ordinary human could withstand. Cain replies to Taizoo's statement that it was as if the defeated fighter has had an unpleasant experience with a Holy Knight; the latter admits to have had one with a Holy Knight from Danafor. Cain's reply makes it seem as though he knows of the now destroyed kingdom's fate. 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. Just then, her skirt appears to be tearing, implying that her size is returning to normal. As Hauser states that he has now become interested in Diane's powers, Elizabeth tells Meliodas that Hauser should not become serious, since, though he is normally an easy-going person, he wouldn't stop once he has become serious. As she says this, Meliodas wonders if she her size has grown a little. Meanwhile, Hauser mentally states that despite him not using weapons, this was the first time any opponent was not affected even slightly by his power, "Tempest". Wondering if Diane is also a Deadly Sin, he then attacks Diane using another technique; much to his shock, she remains unharmed, leading to his confirmation that she is a Deadly Sin.

Not giving up, Hauser forms a gigantic twister, large enough to resemble an actual tornado. As Meliodas and King expresses their worries, Ban states that Hawk will be sucked in by the twister if he lets his feel off the ground even for a moment. 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, and 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 then apologizing again, and walking away.

As Diane apologizes to Elizabeth for ruining her clothes, and Taizoo expresses his surprise at a Holy Knight being defeated, Cain and Meliodas head inside the ring, their battle having been announced. While both of them are being cheered on, Meliodas states that his having to fight the elderly man who gave him directions before is a coincidence, and also adds that Cain's defeating of "Old Fart" did not seem like a coincidence. Cain replies that the world ran on fortuity and necessity, and also that while both him and Meliodas entering the Fight Festival on this day may be a coincidence, him entering the tournament was not. He also questions his opponent, after stating that he became certain when he heard the name "Meliodaz", whether he is Meliodas' son. He is greatly bewildered and shocked when Meliodas answers that he is the man himself. Cain initially refuses to believe so, adding that if Meliodas were alive, he would be in his thirties. Meliodas, stating that he didn't know who his opponent was, questions him as to what if he was the Meliodas whom Cain knew.

When Love Helm begins their battle, Cain states that he found Meliodas' identity hard to believe, but that if he were Meliodas himself; before finishing his statement, he attacks his opponent repeatedly. all of which are blocked, and then jumps back. Removing his cloak and revealing a shirt with a symbol inside, Cain declares that he will not forgive someone like Meliodas, who betrayed the "kingdom he swore to protect", "the people", "the person most important to [him]", and "everything he stood for. Meliodas then recognizes the symbol on Cain's shirt, as Danafor's symbol.
