On that fateful day the rain was heavy. Asuka was drifting in her small rowboat she stole from a dock on a nearby island. Her burden of carrying a five point five hundred million beli bounty isn't easy, with bounty hunters persistent on collecting it thinking she's an easy kill because she's a woman, only to end up dead in their tracks.
She sees a near by ship sailing, sturdy in the thrashing rain. This ship happens to be the Thousand Sunny belonging to the Strawhat pirates.
This day decides not only Asuka's fate but the Strawhat pirates as well.
Particularly the swordsman of the Strawhats. Roronoa Zoro.
