A bad feeling that arose after a sudden win at the casino does not leave Tsunade, so she decides to leave the city as soon as possible. However, Shizune was in the mood to see the city, and she persuades Tsunade Tsunade to at least visit the castle. She agrees, but immediately plans to get away afterwards.
Meanwhile, Orochimaru and Kabuto continue on their way to Tsunade, while discussing how powerful the medicine man is.
Naruto falls down without power during a training session. A leaf from a tree lands on his forehead and he recalls his days at Ninja Academy. One day, annoyed that his students can’t concentrate on their studies, Iruka leaves Naruto, Kiba, Shikamaru, and Chouji for extra classes on concentration techniques. Naruto realizes that back then, Iruka was saying things that would come in handy for him now. The boy blames himself for not listening to his teacher earlier. However, he doesn’t stop trying, so he tries to concentrate again. He ends up having such a powerful explosion that Naruto is thrown from his original location with tremendous force. Jiraiya witnesses the event, but does not yet share with his student the details of the final step to mastering Rasengan . They head off to meet Tsunade.
At this time, Tsunade and Shizune are not far from Tanzaku Castle. Shizune is admiring the view, and Tsunade is already anxious to hit the road. Tsunade’s intuition is not let down, as suddenly the castle collapses and a huge snake with Orochimaru and Kabuto on its head appears in the ruins.
