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 during the flea market.

Background
Nothing much is known about this town, except that literally everything is sold in its 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 him 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, 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, "The 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.
