All around the world, pirates of different ages have set out onto the Grand Line in search of Gol D. Roger's treasure called One Piece. The once ridiculed pirate, Monkey D. Luffy known as Straw Hat, has made his way to the end of the Grand Line with the rest of his crew. Luffy has become the new Pirate King as well. Along the Grand Line horizon, multiple pirate crews have started to band together. They want to control the Grand Line and the islands around them but they need to take down Luffy to control. They have been searching and gathering the Devil Fruit so their forces would have been an extra power boost. A prophet who had just recently died told Blackbeard, the head of the dark pirate crew, that he would rise up and take the world by force.

The evil side has grown pretty fast as Blackbeard has combined with other vicious pirates such as Whitebeard, the newly resurrected Gol D. Roger, the Cipher Pol, Baroque Works and other pirates. The good side may lose with only Luffy, Nami, Robin, Zoro, Sanji, Usopp, Chopper, Franky, Brook, Ace and Vivi {Who have recently joined the crew}. They must now set out to gather more pirates. The only Marines that has sidded with Luffy has been Smoke, maybe Garp, and Kuina. The three great powers are in battle as well, most of the Yonkou and Shichibukai are siding with Blackbeard. Shanks and Mihawk have joined Luffy's side to protect the Grand Line. Even Eneru has come down but on the side of Blackbeard. Dragon hasn't decided yet but aims to aid Blackbeard as he believes his son is worthless and shouldn't be pirate king.

Will you help Luffy or join Blackbeard. The Grand Line's future is in your hands. You decided, Join the fight!
