As Meliodas and Diane continue to fight each other under hypnosis, the fourth and final member of Weird Fangs, Friesia, attacks the disguised Ruin with her insects, prompting Elizabeth to risk her life to protect him. However, as Ruin reveals his true identity, he realises that Elizabeth was going for the bell on his staff the whole time, successfully freeing Meliodas and Diane from the spell to defeat Ruin and Friesia respectively. Meliodas, Hawk, Diane and Elizabeth, who is being carried in Diane's bag, infiltrate Baste Dungeon to rescue Sennett, and find Ban wandering around the prison as well with no sign of having been injured, causing the dungeon's collapse during their happy reunion and breaking a secret barrier that Golgius set up in the process. The six of them regroup back at Dalmary Town, where Dana, who survived the attack, treats them to a meal as courtesy. Meanwhile, King, the bearer of the Grizzly's Sin of Sloth, is shown to be allied with Gilthunder and the rest of the Holy Knights.

News about several sightings of an Armor Giant somewhere in Ordan Forest reaches Helbram, who quickly sends Dawn Roar, an elite group of Holy Knights, to search for the Armor Giant. Meanwhile, Guila visits her younger brother Zeal, and she later kills three thugs who bullied him for his spare change. Meliodas and his friends split up in the nearby village. Elizabeth and Hawk encounter a boy named Alan, who is looking for some glue to repair armor. Upon hearing the low growls that echo in the forest, Meliodas, Ban and King find the Armor Giant being surrounded by Dawn Roar, but Meliodas, Ban and King are no match against Dawn Roar. Just as it seems that the Armor Giant is about to be slain, Alan intercepts and reveals himself as Gowther, the Goat's Sin of Lust.

The Seven Deadly Sins and the Holy Knights all combine forces in an attempt to defeat Hendrickson. Meliodas, given support from his friends and allies, uses his ultimate technique to finish Hendrickson off. When Bartra appears with Merlin, he commands the Holy Knights to restore the kingdom and preserve its people as their "punishment" for starting a holy war. Bartra then thanks the Seven Deadly Sins for saving the kingdom and protecting Elizabeth. Hawk is revived as a piglet, much to a surprise. Things return to normal inside the kingdom, and a festival is held at night. The next day, Elizabeth joins Meliodas, Hawk, Diane, Ban, King, Gowther and Merlin in finding the last member of the Seven Deadly Sins, Escanor, the Lion's Sin of Pride.
