The hunt for the last sin begins.

After surviving the Abandoned Island, Rex and his crew sail to the legendary Whale Island, a heaven for bounty hunters and the secret base of the Rebellion. To stand against Vaelor's Crime Syndicate and the Emperor of the Seven Hell Kings, they need more than guns. They need Pride.

But Pride has a name: Jack. A bartender from Mystic Land with a 500 billion gold bounty, now a slave in the most brutal place on the sea, the Kingdom of the Damned Pirates.

One cursed island. One thousand pirate ships. One hundred thousand pirates. And at its center, a monster who became a leviathan.

Sandy must master the blue lightning of Wrath that rules the sky. Sindy must master the blood of Lust and learn to walk in sunlight. Rex Goldfang must lead his Greed against an empire.

When the Pirate King drinks the Kraken Potion and unleashes the Ancient Trap, a black smoke that freezes souls in nightmare, only one man can walk on water through it in sea boots and a formal suit.

My fun time is over. I am Pride. The strongest sin.

Wrath, Greed, Lust, and Pride, four sins together at last. The war for Whale Island begins now.
