Precursor to a New Adventure! Apis, a Mysterious Girl!

On a stormy night, a girl called Apis escapes from the Marines and is found drifting by the Straw hats. Upon learning that they are pirates, Apis hides some of the reasons why she is being pursued by the Marines. When the marines locate them, Apis tells the Straw Hats of an impending gust of wind. While this allows them to escape the Marines, it winds up sending them into the Calm Belt.
