Synopsis
Naruto and Guren help each other from the hungry mini Three-Tails as Rinji's men attack Lee's group. Yūkimaru and Kakashi devise a plan to track the Three-Tails with the boy's power and get Naruto and Guren out. After Naruto and Guren escape from an illusion making fog, Naruto begins to realize Guren's good intentions.
