"A Fierce Battle of Rolling Thunder!" (ゴール直前!雷鳴とどろく大激闘, Gōru Chokuzen! Raimei Todoroku Daigekitō) is episode 105 of the original Naruto anime.
Fukusuke continues to celebrate with women and food when Aoi warns him that he might be celebrating prematurely. Naruto Uzumaki, carrying Idate, ascends the long flight of stairs to the Modoroki Shrine. Idate grabs the orb and heads out on his own two feet, but they are soon confronted by Aoi, waiting with his sword of the Thunder God. Both Naruto's Rasengan and Sasuke's Chidori are repelled by the sword, though the latter is able to crack it slightly.
