Hendrickson tries to convince Arthur to leave the castle, but to no avail. Instead, Hendrickson escorts Arthur inside the castle and suddenly engages him in battle. Meanwhile, Elizabeth and Hawk are teleported inside the dungeon of the castle, and they try to find a way out. Meliodas, Ban and Gowther manage to defeat the army and sneak inside a town of the kingdom, while King summons his black hound Oslow to use its mouth to teleport Diane inside the castle. However, Diane is attacked by Guila, Jericho, Gilthunder, Howzer, Helbram and Great Holy Knight Dreyfus. Diane tries to defend herself, but Dreyfus overpowers her with an attack that sends her crashing onto the town streets. After Diane wander the streets and protects Zeal from being crushed by a falling building, both Howzer and Guila switch sides to defend Diane.

Ban explores the catacombs under the city. Merlin and the other sins go to the chamber where the king Baltra and Elizabeth are being held captive. Dreyfus has a confession.

Ban attempts to kill Meliodas, but is stopped by Hawk. Meliodas and the sins corner Hendriksen and prepare to take him down.

Hendrickson unveils the source of his power, the corpse of a red demon, which is the same one that Ban slayed in the Fairy King's Forest long ago. After Ban pummels Hendrickson through the ground, Meliodas, Ban, King and Gowther jump down the hole to a cave, where Hendrickson injects himself with the blood from the corpse of a gray demon to acquire even more power. A sudden burst of energy from Hendrickson sends the four of them back above ground, where Hendrickson easily overpowers all of his opponents despite all of their efforts. With Meliodas left standing and protecting Elizabeth, Hendrickson casts a large dark blast, but Hawk sacrifices himself in order to save the two of them. Shocked of losing her dear friend, Elizabeth awakens her dormant powers that repels Hendrickson and heals everyone else. However, Hendrickson survives and still has strength left in him to fight.

Ban and Meliodas meet to continue the duel they left unfinished before, only to find that Hawk has told everyone about their solemn battle.
