Query: Really violent---very cool

One Piece is a very awesome manga. Don't be fooled by the TV show, it's awesome. But take heed -- it's really violent. I recomend this for readers 11+ It is so worth the whopping 8 bucks I have to pay eeeeveryyy time. I just think mebbe Eichiro Oda needs to CHILLAX with all the blood and gore. This is mainly based for boys, but like me, I like it just as much. Don't get me wrong, this manga/volume is great!
