The Seven Deadly Sins: Cursed by Light

Six months have passed since the Sins disbanded after defeating the Demon King and Cath Palug. Meliodas and Elizabeth travel together to visit the places she lived in her previous lives, ahead of their coronation. The journey deepens their bond as they confront memories of the past and looming responsibilities.

On the road, Meliodas encounters his younger brother Zeldris and his beloved Gelda, who are on a similar quest before returning to the Demon Realm. The brothers compare notes about their duties and vows, reaffirming their complicated relationship. The moment sets the stage for the looming threats ahead.

A fatally wounded demon reveals that the Demon World has been overrun by a fairy and a giant. The revelation confirms Dahlia and the 'Giant Master Craftsman' Dubs as the culprits behind the turmoil. The brothers are overpowered and Meliodas and Elizabeth are captured and taken into the Demon World.

King and Diane marry in the Fairy King's Forest, with Ban and Gowther in attendance as witnesses to a rare moment of peace among the Sins’ allies. The ceremony marks a hopeful milestone for the alliance against looming threats. The celebration hints at the stabilizing forces at play before chaos erupts again.

Back in Liones, King Bartra holds a coronation to celebrate Meliodas and Elizabeth’s return. The ceremony strengthens the realm’s resolve as new alliances form against external forces. It stands as a counterpoint to the devastation unfolding elsewhere.

An army of fairies and giants assaults the Fairy King's Forest wedding, aiming to punish the Sins and their allies. The Sins manage to defeat the assault by disarming the weapons Dubs crafted to maintain Dahlia’s enchantment. The victory reveals the scale of the threat that still looms over both realms.

While the celebrations continue, the Liones coronation faces a simultaneous onslaught by the revived foes. The Sins rally to defend the palace and neutralize the threat, once again exploiting the weakness of Dahlia and Dubs’s enchantments. The battles reaffirm the fragile balance between the worlds.

Back in the Demon World, Zeldris convinces his kin to help free Meliodas and Elizabeth. The brothers swap opponents to try to defeat Dahlia and Dubs, who are revealed to be under another's enchantment. The rescue effort rekindles the brothers’ alliance and sets the stage for a deeper confrontation.

Mael arrives in Liones to warn everyone of an attack by the revived Goddess Race, issued directly by the Supreme Deity. The Supreme Deity commends the Sins for defeating the Demon King, yet she intends to destroy them to end the Holy War. The warning escalates the looming crisis.

The Supreme Deity overpowers the assembled group until Meliodas and Zeldris arrive with Elizabeth. Meliodas reveals that his time with the Demon King granted him memories showing that the gods were created to fight each other, treating the Holy War as a game. The pair defeat the Supreme Deity, though she warns that her death would unleash chaos upon the world.

Following Meliodas and Elizabeth’s wedding and coronation, the celebrations reach a quieter note with Hawk and Wild in attendance. Meliodas shares a drink with Zeldris, who grants him freedom to move between the Demon World and the human world. The brothers rekindle their bond, signaling a new era of cooperation.

Meanwhile, Arthur slaughters a faction of Dahlia and Dubs’s mind-controlled minions while rebuilding his kingdom. Merlin appears and informs him of the Supreme Deity’s demise and that the Age of Humans and Chaos can truly begin. The future shifts from war to an uncertain balance of power across realms.
