In the times when pirates ruled the seas as if they owned them, all the sailors were in fearful trepidation.
There were many pirate ships in the seas, but one was an unusual ship with two captains.
Captain Black and Captain White commanded the ship called "Black Lily."

These two captains had the authority to do what they wanted for all the treasures. For them, there was nothing to fear. Overestimating their power, they dabbled in the forbidden treasures. These hiden treasures cursed them and Captain black turned into a hideous monster! Captain Black called to the Kraken sea monsters and made them attack Captain White and the sailors. The sailors just escaped with their lives in this catastrophic situation. From that day, they were never seen again on the seas. To this day, there is a rumor that Captain White survived and became addicted to drinking. Once he was invincible, but now he's just a shadow of his former self.
