One Piece Volume 13 concludes the gang's confrontation on Whisky Peak with the criminal organization Baroque Works, and sees new faces join the crew: Princess Vivi of Alabasta, and her sidekick-duck Karoo. Their journey continues on to Little Garden, where they are introduced to giants Dorry and Broggy.
This is a pivotal volume, as it sets the stage for the first massive saga of the series. Several key characters are either introduced or hinted at, and the Straw Hats are put on Baroque Works' most wanted list. It also starts the Little Garden story arc, which was one of the many story elements 4Kids cut from their dubbed version. One Piece fans should enjoy seeing the story play out as originally intended.
The overall translation is pretty good, and several key character names (Mr. Bushido, All Sunday, Goldenweek) have been retained from the Japanese version. Viz uses a unique spelling for Elbaf (Elbaph) and Vivi's last name seems to have an extra 'l', but the latter also showed up in some of the video games in Japan. A recommended buy, the next volume comes out in April.
