Though hesitant at first, the two apprentices drink the creature's blood. Twigo explodes due to being incompatible to it, while Jericho survives, and becomes part of the New Generation of Holy Knights. Meanwhile, Meliodas and the rest arrive at Byzel, him speculating of a sacred treasure being one of the items sold in the town's annual flea market. Upon being directed to a battling tournament, Meliodas and Ban readily enroll themselves, and King, who unwittingly joins them. The tournament's participants are shown to also include Howzer.

Not long after the drawing of lots to decide the match-ups for the main tournament, the first battle of the first round begins with Matrona, the aforementioned young girl, and Griamore facing off. Just before the battle begins, Matrona removes her cloak, unveiling her identicalness to Elizabeth.

When he declares that he will humiliate Meliodas next, however, Matrona, now enraged, quickly destroys his ability, and then him, with a single punch. Victorious, Matrona skips towards Meliodas, believing her identity to have been discovered, but is greeted by Meliodas' question as to the same. Infuriated, She punches him and leaves, and replies in a surprising manner when King questions her about Diane and Elizabeth.

Immediately afterwards, King, under the alias of Old Fart, battles Cain, only to be easily defeated even after using his ability, "Disaster". Meanwhile, Howzer discovers that Meliodaz and Baan are, in fact, the Deadly Sins, as he had suspected before. Finally, the final match of the first round is declared as between Meliodas and Ban.

Chapter 34
Howzer learns of Meliodas and Ban's identities. As Ban and Meliodas' battle begins, Meliodas punches Ban in the face, which reminds the latter of their first meeting, and how he ended up joining Meliodas for continuing their fight then. In the present, the two prove to be evenly matched, with Ban having the advantage in speed but Meliodas, in his physical strength. The battle causes much damage to the surroundings, and just when Meliodas is about to gain the upper hand, both opponents fall - with Ban ominously pointing his hand towards Meliodas, having used Snatch.
