The "Summit War" Saga (“頂上戦争”編,"Chōjō Sensō" Hen?), also called the Whitebeard War Saga and the Paramount War Saga in the official Viz release, is the sixth saga in the anime and manga series, One Piece. It is also the last saga of the first half of the series.
Upon reaching Sabaody Archipelago, they are separated and sent to different parts of the world by Bartholomew Kuma, another Shichibukai. Luffy is sent to Amazon Lily, where he befriends the Shichibukai Boa Hancock, who falls in love with him. Upon learning of his brother's impending execution, Luffy makes the difficult decision of rescuing his brother first before reuniting with his crew. Hancock takes him to Impel Down where Luffy breaks in and, upon discovering he is too late, breaks out of the great prison with the aid of Emporio Ivankov with his Okama party and two former Shichibukai, Crocodile and Jinbe. They escape and arrive at the battle at Marineford, with Luffy allying himself with the Whitebeard Pirates. The war ends with the deaths of Ace and Whitebeard, the former breaking Luffy physically, mentally, and emotionally and the latter creating a change in the world forever. After being rescued and taken back to Amazon Lily, he is shaken away from his depression by Jinbe. Luffy decides to train and become stronger with the aid of Silvers Rayleigh in order to go to the New World. However, before doing this, he sends a message to his crew mates that they must become stronger too, and that they will reunite again at the Sabaody Archipelago after two years of training.
