In a realm resembling the medieval era of Europe, the Holy Knights of Britannia, feared and respected for their potent magic, safeguard the land and its realms. Among them, a faction known as the 'Seven Deadly Sins' allegedly betrayed their kingdom by rebelling against the ruler of Liones. Despite their defeat, whispers persist about their survival. A decade later, the Holy Knights orchestrate a coup, becoming the oppressive rulers of Liones. Inspired by the popular manga series, Nanatsu no Taizai chronicles Princess Elizabeth's quest to locate the Seven Deadly Sins. Together, they aim not only to reclaim the kingdom from the tyrannical Holy Knights but also to uphold justice in a world plagued by injustice.
