A Log Pose to Nami
When Nami is kidnapped, the only one who knows is Luffy, and he must risk the Grand Line alone, barefoot, and in a log. The only things guiding him are a ship on the horizon, and the will to see her again.
Luffy's Fish Tank
Nami talks with Luffy about treasures at the bottom of the sea, and fish tanks.
I.O.U.
Luffy pays Nami for some services rendered, but ends up owing her three hundred million and a thousand berries.
The last two of this series-ish thing are more heavily on the romance side, but the first is full of action, and is my personal favorite anyway.
So any comments on 'em? I'm planning to write a lot more oneshots because I'm waiting for the Thriller Bark arc to be near to ending before I write the longer sequel.
