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 of Liones following its near annihilation by the Demon Race, Elizabeth and The Seven Deadly Sins decide to celebrate King Bartra’s birthday with numerous dishes being prepared in the Boar Hat tavern. The Deadly Sins’ leader Meliodas and his talking pig companion Hawk search for Skyfish for a recipe, ending up above the clouds and in front of the Sky Palace after stumbling across a well in the nearby forest which they discover is a portal.

Living in the Sky Castle are a race of winged people known as the Celestials, descendants of the Goddess Race who hold watch over an Indura-type demon sealed in their land since the Ancient War’s end 3,000 years ago. But when a group of demons calling themselves The Six Knights of Black attack the Celestials and release the Indura, forcing a Celestial youth named Solaad unintentionally bring Meliodas and Hawk to his people’s land while he left to find the legendary white pig ‘Oshiro’ whose power was used to seal the evil.

Solaad ends up meeting the other Deadly Sins, who mistook him for Meliodas due to their similar appearances, but manages to convince them to come with him while Meliodas went through a similar case of mistaken identity with the Celestials.

As The Seven Deadly Sins face the Six Knights of Black with support by the Celestials’ warriors, it is revealed that the Knights of Black’s leader Bellion is an upper-class demon who was denied membership into the Ten Commandments by Meliodas in the past. Meliodas ends up being mortally injured by the Winged Sword, a sacred sword forged specifically to harm demons.

But Solaad, trusting The Seven Deadly Sins’ insistence that Meliodas is a good person, removes the sword and revives Meliodas. Solaad then uses the Winged Sword and the combined power of his people, the Sins, and Elizabeth to destroy the Indura. The Sins are hailed as heroes and celebrate with the Celestials before taking a Skyfish and returning to Liones on Hawk’s Mother, who is revealed to have been ‘Oshiro’ the entire time.

Some time later, Batra is presented with the cooked Skyfish and is appalled by its horrible taste as Meliodas cooked it. Hawk decides to eat it for him and ends up assuming a Skyfish form to his shock.
