Nanatsu no Taizai: Edinburgh no Kyuuketsuki

Twelve years ago, a dire warning reached the Kingdom of Liones from its neighboring realm of Edinburgh. A messenger arrived with harrowing news: vampires had emerged within the territory, unleashing devastation upon its people. The citizens of Edinburgh were mercilessly slaughtered or forcibly transformed into bloodthirsty creatures of the night, and the once-thriving capital was entirely seized by these monstrous invaders. In response to this catastrophic threat, Zaratras, the captain of the Holy Knights, convened an urgent council alongside fellow knights Dreyfus, Hendricksen, and Meliodas. During this critical meeting among the kingdom's leaders, a decisive strategy was forged to reclaim the fallen city. It was resolved that a specialized order of elite warriors would be assembled to confront the vampire menace head-on. Thus, the formidable group known as the Seven Deadly Sins was formed. Composed of extraordinary fighters chosen for their unmatched strength, this newly established band of knights was entrusted with a singular, monumental mission: to march upon the corrupted lands of Edinburgh, eradicate the vampiric forces holding it hostage, and restore the stolen capital to its rightful state.
