In the chaotic Great Pirate Era, Marine Colonel Laurentina “Ghost Shark” leads the newly formed Deep-Sea Fleet—a unit meant not for glory, but for the bloodiest front lines. A white-haired vampiric prodigy who once clashed with the Golden Lion, she’s determined to turn a pirate-infested West Blue into a second East Blue, starting from the cursed Crescent Moon Island.
With a time-bending scientist, a battle maniac medic, a lovestruck sniper, and a robot orca girl at her side, Laurentina fights pirates, corrupt nobles, and even rotten Marines—exposing a Vice Admiral’s massacre live to the whole world. In a sea where everyone claims “justice,” Ghost Shark’s fleet sails with a simpler creed:
If dawn won’t come on its own, we’ll carve it out of the dark.
