Nanatsu no Taizai

A group of warriors known as the Seven Deadly Sins was exiled after being accused of attempting to overthrow the monarchy. Princess Elizabeth later learns that they were betrayed by the Holy Knights, who framed them and orchestrated the assassination of her father to take control of the throne. Determined to reclaim her kingdom, she sets out to find the Sins. Her first encounter is with Meliodas, who runs an inn and owns a talking pig, and appears to lack the strength expected of a legendary warrior.
