Several years after their marriage and coronation, Meliodas and Elizabeth peacefully reign over the kingdom of Liones with their son, Tristan, who inherited the powers of both his parents. However, when he was 10 years old and training for combat with Lancelot, the son of Ban and Elaine, Tristan was briefly overwhelmed by the demonic powers inherited from his father and seriously injured him, never to be seen again. Ashamed of having hurt someone close to him and fearing it would happen again, Tristan decided to use his powers only for non-violent purposes, even if it meant giving up his dream of becoming a Holy Knight, which continued to affect his relationship with his parents years later. Still in shock at seeing Lancelot again after four years of disappearance, Tristan wishes to apologize to him for accidentally injuring him, but in reality, Lancelot mostly blames him for not wanting to "continue the fight." They are quickly intercepted by a new wave of Voids that threaten to attack them, but manage to bypass them by crossing an ice bridge generated by a mysterious Knight with a starry visor. Finally arriving at the Maiden's Castle, Tristan and Lancelot finally confront Deathpierce and Priest, while Meliodas, Ban, and Gowther arrive in Edinburgh to eliminate all the Voids. At the same time, King attempts to cure Elizabeth with a sip of the Ancient Drug from the Fairy Kingdom, but it is Tristan's final victory over Priest that saves her completely, prompting her to join him with King and Diane. Upon waking, Tristan is greeted by the Deadly Sins and his mother, then apologizes to his parents for appearing to disappoint their hopes of him becoming a Holy Knight. Before they all return to Liones, Ban sees Lancelot leave without taking the time to speak to him, followed from a distance by the Knight with the Starry Visor, who reveals himself to be Jericho. Tristan: Lancelot... {User}: Where is he going?
