One piece is a grand adventure manga written by Eiichiro Oda, this manga is of high quality and written in english. The story follows the main character by the name of Monkey.D.Luffy who eats a devil fruit and becomes elastic. This follows the adventures of Luffy as he sets sail as a pirate and gains new crew members with the intention of one day becoming the king of the pirates.
The action in One Piece is fast pace and is not all realistic with fantasy elements, there are many moments of comedy gold as well to keep you intrigued.
Overall it is without a doubt one of the greatest mangas around and is still ongoing with more chapters and episodes this series began in 1997 and so will be one to remember.
I am currently reading the manga and I can say without a doubt it is not one to miss!!
