One Piece Volume Six is a manga by Eiichiro Oda, and it was published by Viz Media’s Shonen Jump imprint in 2005. The series is rated “T” for teens; from what I’ve read of the One Piece series so far, I would agree with this rating.
Volume Six picks up exactly where Volume Five left off. Luffy is working as an errand boy at Baratie, the ocean-going restaurant that he accidentally damaged it by sending a cannon ball in its direction. He meets the sous-chef Sanji, and Luffy is determined to have him join his pirate crew; unfortunately, Sanji doesn’t want to leave the restaurant.
At the end of Volume Five, Sanji gave free food to a man named Gin, who is a member of Don Krieg’s pirate crew. Gin brings Don Krieg to Baratie in order to get some food, because Don and his men are in bad shape after returning from the Grand Line. Over the others’ objections, Sanji feeds Don Krieg. Instead of being grateful, Don Krieg declares that he’s going to take over the restaurant.
While Don Krieg’s pirates and the cooks at Baratie fight it out, another player enters the scene: Hawk Eye Mihawk, the best swordsman in the world. Zolo decides to have a duel with Hawk Eye in order to keep a promise and to prove that he is the best swordsman in the world.
Unfortunately, this storyline does not resolve itself in Volume Six, so you have to read Volume Seven to find out what happens next. I actually watched the anime episodes that corresponded with this manga volume not too long before reading it, so this made Volume Six an easy read for me. Overall, the anime seemed to stay rather faithful to the events that took place in the manga telling of the story. The only real difference I saw was the fact that in the anime, Sanji’s backstory was introduced during the section of storyline that’s depicted in the manga. I suspect Sanji’s backstory appears at some point later in the manga.
