Byzel Fight Festival

 * Meliodaz vs. Matrona

Long Summary
The great boulder of Byzel cracks further due to Diane's punch, due to which Love Helm directs the audience to evacuate. Meliodas realizes Ban's plan in order to have him and Diane Meliodaz vs. Matrona fight properly, and as the enraged Diane attacks him, tries to convince her that it was a misunderstanding. She refuses to believe so, and he, narrowly dodging one of her punches, comments that he would have to fight her seriously. Both exchange a barrage of punches and attacks, the magnitude of whose power is so great, that the entirety of the huge boulder on which the ring of the Fight Festival is located, begins to shake, as the frightened audience looks on.

The battle continues, with Diane kneeing Meliodas in the chest, and almost pushing him out of the ring with a punch, when he retaliates. Cain ponders on Diane's identity, since her power is on par with Meliodas'; Hauser then ponders on Diane's size being normal, since she was said to be from the Giant's Clan. In the battle, Diane charges at Meliodas again. As he punches her back, he questions her as to the reason her strength is as powerful, even after shrinking. He then jumps, and tries to land a punch from above, stating that this was the end. Diane, however, stops the punch with one of her own, and then pushes Meliodas back when he tries to attack her again. As she does so, her size is shown to be returning to normalcy, having shrunk due to a Chicken-Matango previously.

As Diane continues growing to her normal size, and punches Meliodas, stating that she will never forgive him, he escapes through one of the cracks their battle has created on the ring, and continues to slip through the cracks to flee from every one of her attacks. While Hauser doubts if the Deadly Sins were really criminals, the audience expresses its disapproval and dislike at the low seriousness of the battle. Meliodas, Diane, Ban and King seem to be alarmed by something, and Diane, still sitting on Hawk, appears to be returning to her normal size like Diane.

Meliodas accepts the audience, and states that the "comedy routine" has now ended, and that he will now be taking over Byzel, also adding that had the audience only played along, they would have lived that much longer. While the audience watches disbelievingly, Meliodas displays his symbol of the Dragon, and declares his identity as the captain of the Seven Deadly Sins, and the Dragon's Sin of Wrath. As the civilians argue that his appearance is very different from his wanted poster's image, but then notice his and Diane's symbols - the latter being the Serpent's Sin of Envy - Ban and King also enter the stage. Ban and King are immediately recognized, the former, due to his appearance resembling his wanted poster's image, and his symbol, and the latter, due to him having transformed into his fatter and adult form, which resembles the image on his wanted poster.

Meliodas continues that the four Sins have taken a liking to the town, but that he will give the civilians a chance since he is in a good mood: he orders every one of them to get out of Byzel in one minute, lest they be massacred by them. As they extremely shocked people watch, Elizabeth questions their actions, and Hauser wonders if this is the Sins' true nature.
