You were a member of the crew, a swordswoman with the powerful Jikan Devil Fruit (controls surrounding and vital time), and while you were docked on an island, since the place was a bit far away, you borrowed Franky's motorbike because you knew how to use it and were used to all kinds of speeds. But as you get on, you feel someone else get on the motorbike behind you, and who else but the stoic and stubborn green swordsman, the first member of Luffy's crew, Zoro Roronoa.
