The Seven Deadly Sins: Prisoners of the Sky

The story takes place in a time when humans and non-humans alike lived in the same society. The Kingdom of Liones was almost annihilated thanks to the evildoings of the Demon Clan, but were saved thanks to the efforts of the Kingdom’s third Princess, Elizabeth, and a band of strong yet terrible knights known as the Seven Deadly Sins. With peace returning to the Kingdom, preparations are underway to celebrate the King’s birthday. Dishes using lots of rare ingredients are being prepared at The Boar Hat, which is being run by the leader of the Seven Deadly Sins, Meliodas. Read more on Wikipedia.
