The Seven Deadly Sins: Grudge of Edinburgh Part 1

The Seven Deadly Sins: Grudge of Edinburgh Part 1 is a single-episode original net animation that continues the story of the beloved fantasy action series. Set fourteen years after the events that brought peace to the Kingdom of Liones, the story follows Prince Tristan as he grapples with the conflicting powers inherited from his parents—the Demon Clan ability from his father Meliodas and the Goddess Clan power from his mother Elizabeth. When Elizabeth faces mortal danger, Tristan is forced to flee the kingdom, setting his journey toward Edinburgh in motion.

This standalone ONA arrived in December 2022 and has finished airing. It serves as a bridge narrative that draws the Seven Deadly Sins back into events unfolding around Prince Tristan's desperate circumstances. The episode explores the mysterious intentions of Deathpierce, a former Holy Knight of the Pleiades of the Azure Sky who now commands a castle in Edinburgh, as fate begins to move once again. Fans of the original series will find familiar themes of action and adventure mixed with the comedy and fantasy elements that define the franchise, while newcomers can jump in to see what brings the legendary group back into play.
