In the final showdown with Sasuke in the Valley of the End, Naruto was thrown into the pirate world by the space-time ninjutsu due to the huge energy collision, and fell in front of Luffy. Two "idiot" heroes met and instantly became close friends because of their "meat". With the help of his shadow clone and Rasengan, Naruto easily took down Colonel Morgan, which attracted the initial attention of the Navy Headquarters. At the end of the volume, with a mentality that was half curious and half helping his friends, he and Luffy shouted together: "Let's go to the Grand Line!"
