Capital of the Dead「
The rumor about the area has led travelers and rich people to settle, and subsequently establishing the Tala Village at the entrance of the Capital of the Dead. A living individual cannot enter the place even if they just desire to. However, a common saying, "A priceless memory shared with the deceased will open the path to the capital," implies that a person who shares a precious memory with a deceased person can enter the place without dying.
The Boar Hat gang decided to travel to the Capital of the Dead to find King who went there to find his deceased sister Elaine. The Boar Hat ended up traveling there with Ban and King memories of Elaine. Ban immediately notices a girl and rushes in her chase, with King, in turn, following Ban.
While Ban was away chasing the girl, Meliodas and Diane face off a Holy Knight named Guila who killed herself to be there and notice how dangerous she was, Meliodas told Elizabeth to escape with Hawk while the two fights. In response, Meliodas draws his broken blade and utilizes Full Counter against Guila, who reveals that she knows the ability and a way to avoid it.
As Ban was chasing the girl and King was following him, King and Ban end up having another fight. King narrates how he came to discover his hometown to have been burned to the ground, then trapping Ban by transforming his pillow into a giant stuffed bear, and angrily reveals that the Guardian Saint whom Ban killed was his sister. When Ban, in response, declares that he is immortal, King uses a form of his sacred treasure that petrifies all whom it impales. Ban's skin around the impaled area are shown to have petrified.
When Ban turns completely into a statue and King leaving the body behind, King notices spheres of light approaching Ban, and as he recognizes the spheres to be Elaine, she kisses Ban in order to break King's curse. They exchange their greetings, when King confusingly yells at them, questioning whether Elaine was still angry at him for leaving her and his kingdom.
The three are distracted by a huge explosion some distance away. Noticing that a Holy Knight has arrived, Ban proceeds to head there, but only before telling Elaine that he will definitely make her his someday. Ban end up joining the fight but even with Ban on the team, they were getting badly hurt.
King continues questioning Elaine why she forgave Ban and not him, but Elaine explained to him why she couldn't forgive King so easily. Before King says anything else Elizabeth and Hawk comes running by whilst trying to escape from Guila.
King asks who they are, so Elizabeth and Hawk introduces themselves and that they are currently traveling with Meliodas. Elizabeth tells him what is happening in the battle field who in response, ask him to help her, but when he refuse, King was surprised by Elizabeth bravely tells him to run away instead and tries to borrow his spear to fight against Guila. Feeling inspired by Elizabeth's bravery, King activates levitates and heads to the battle.
As the battle continues, the Sins were losing but then King arrived and offers to help them and fight Guila alone. After King defeated Guila with ease. Elaine revealed that King was the Fair King of they home Kingdom. King then turns away from the defeated Guila, but Guila gets out of the rubble and attacks King. King then saved by Meliodas and notices that Guila's presence has left.
Afterwards King along with the rest are rejected by the capital, which Elaine thanks him for protecting Ban before they leave.
- The Capital of the Dead does not hold the souls of those who are reincarnated, nor of those who are stuck in Purgatory:
- Liz did not appear when Meliodas entered because she was reincarnated into Elizabeth, as with all of Elizabeth's past lives before.
- Meliodas did not appear before Elizabeth because his soul was stuck in limbo in Purgatory preparing for his revival.
- Matrona was not shown when Diane visited the Capital because she was alive the whole time, and possibly because Diane held mixed feelings towards her.
