The princess joins him on his journey to find the other Deadly Sins in order to defeat the Holy Knights, who have orchestrated a coup d'état and have overthrown the king.

Gilthunder, thus preventing the village from making the Bernia ale, which was their prime source of income. After innumerable unsuccessful attempts of the villagers to remove the sword with which the source was blocked, Meliodas easily removes the object. A celebration is held at the Boar Hat, and Meliodas was hailed as a savior by Bernia's villagers. Gilthunder, wanting to confirm whether the removal of his sword was an accident, threw a spear imbued with his power toward the town. Meliodas, however, easily stops and throws the spear back, destroying Fort Solgales.

Meliodas, Hawk and Elizabeth travel to the Forest of White Dreams that even Holy Knights avoid. There, the Prankster Imps that inhabit the Forest of White Dreams attempt to confuse them by impersonating Hawk and Elizabeth in order to lead them away. After defeating them, they follow them and find the Serpent's Sin of Envy, Diane sleeping in the forest. Gilthunder suddenly arrives and binds all of them with his lightning magic. Meliodas battles Gilthunder, purposely allows the Holy Knight to slash him, and under the pretense of dying due to the grave wound, acquires information about the whereabouts of two members of the Seven Deadly Sins, King and Ban, as his apparent last wish.

Having discovered the whereabouts of Ban and King, Diane throws Gilthunder out of the forest, and Meliodas, Hawk and Elizabeth, now joined by Diane, head toward the Baste Dungeon, where Ban is imprisoned. They later arrive at Dalmary Town where Meliodas is treated by Dana. Diane and Elizabeth begin to argue and discuss about the aspects in which they envy each other. They are suddenly attacked by the Holy Knight Friesia, who tries to destroy the entire town along with the Deadly Sins, but Diane quickly destroys all of her insects. Concurrently, Ban escapes from his cell in the Baste Dungeon, and is stopped by Jericho, who tries to subdue him. Dana unexpectedly reveals that the medicine Meliodas drank was a deadly poison as Golgius appears out of the blue.

Golgius appears and attempts to take Elizabeth and Meliodas' sword back to Liones. Whilst attempting to take the sword, Meliodas awakens, with no effect of the poison showing, proceeding to blast an aura that causes Golgius to make a hasty retreat. Meliodas and Elizabeth set off to Baste Dungeon afterwards, however, they are stopped by a confused Diane, who after hearing the sound of a bell, attacks the group. They try to run away from the berserk Diane, involving a pair of shepherds along the way, however Meliodas soon succumbs to the same bell, and begins to fight Diane. Meanwhile in Baste Dungeon, Ban is shown wandering around after having dealt with Jericho. It is not long before he is found by Jude of the Weird Fangs, who promptly stabs Ban in the chest.

Meliodas and Diane are still fighting each other; Elizabeth shouts for them to snap out of it, and for a few moments they do, until the sound of the bell once again spurs them to fight each other again. The Holy Knight Friesia comes in, threatening the life of the shepherds, however Elizabeth steps in to protect one of them, heavily injuring herself in the process. It is then revealed that one of the young shepherds is actually Ruin, and that he has been fooling them all this time. As Elizabeth gets beaten up by Ruin, she manages to knock off the bell that is causing the hallucinations; Ruin goes to punish Elizabeth further for doing so, but Meliodas quickly comes to her aid, thus beginning Meliodas' battle with Ruin, whilst Diane faces off against Friesia. Both defeat their respective opponents, and the team continues their trek to Baste Dungeon. Elsewhere, despite having been pierced in the chest, Ban is able to overpower Jude, and takes him out. Meliodas and co. finally enter Baste Dungeon, although it is all a trap as Golgius locks them in with the Eternal Seal Spell. However, the reunion between Ban and Meliodas caused so much destruction that it completely destroyed the structure and disregarded the spell. Later that evening, the gang enjoys a meal courtesy of Dana, but an omen in the sky foretells of great disaster to befall Britannia soon. In Liones, it is revealed that King is alive and well, but he is working with Gilthunder.

Meliodas picks the ggroup's next destination to be the rumored location of the King, the Capital of the Dead.

The battle with the King comes to a close as he overpowers Guila with Chastiefol. Their time in the Capital of the Dead now over, Ban and Elaine have one more close moment, before being bid a farewell by Ellen and Luigi, who are revealed to have been ghosts this entire time...
