Fukusuki continues to celebrate with women and food when Aoi warns him that he might be celebrating prematurely. At the bottom of Modoroki Shrine, Naruto begins his ascent up the long light of stairs to the top of the shrine.
Along the way, Naruto asks about Idate's 10th problem. It was explained as a competition among the 3-man genin teams. Among teammates, one person will fail and remain a genin forever. But they also had the choice to quit now and take the exam in six months. If one person quits, the entire team will fail. Most of the people in the room remained. When Ibiki scanned the room, he decided that everyone who remained fails. Idate asked his brother why he failed everyone, but Ibiki simply told him that a ninja must understand all his circumstances. He must figure out the answer on his own.
When the boys finally reach the top, Idate grabs the orb and heads out on his own two feet.
Aoi warns Fukusuki to cross the bridge so he can destroy it. When Idate comes up to it, Aoi is waiting with his sword of Raijin. Naruto smacks Aoi with a mud ball and uses Kage Bunshin to form Rasengan. He then tries to take on the invincible lightning sword. The Second's grand katana wins the battle and Naruto is thrown back. Aoi then directs his attention to Idate.
That night long ago, Ibiki reprimanded Idate for leaving with the stolen goods and demanded he turn himself in. Aoi used his rain army to capture and torture Ibiki until he agreed to translate a scroll. Ibiki refused while his little brother watched and even renounced being a ninja. Ibiki plotted his and Idate's escape. As he ran, the building exploded behind him. He never went back to Konoha.
Aoi explains that Ibiki never betrayed his brother or his village. As he is about to strike, Sasuke and Sakura join the battle. Sasuke tries Chidori but he is thrown back. Aoi laughs at the legendary Uchiha's weakness and Sasuke demands he take it back. Angrily, he forms another Chidori and manages to crack the lightning sword before being caught up in the Raijin's energy blade. When Aoi tosses Sasuke aside, Sakura runs to his rescue and both topple over the cliff
