Following her council with Hidden Leaf officials and an inquiry of Naruto Uzumaki being at Mt. Myoboku, Tsunade leaves for the Land of Lightning to meet with the other Kage to discuss the Fourth Great Ninja War and provide intel of a possible Akatsuki location that Anko provided. While she agreed that they should form a fifth independent intelligence---gathering organization, she is upset to find the other Kage want to hide Naruto and Killer Bee on an island Ay selected instead of having them participate in the war. Tsunade relents after Gaara provides a just cause for the decision and meets with Ay after to request Bee's help in training Naruto to use the Nine Tails's power. The Raikage reveals her request is not needed as the island he selected happens to be where he and Bee trained in their younger years. Tsunade later makes the arrangements while lying to Naruto that he is on a "top-secret, S-rank mission" with Yamato to the "resort" island mentioned in the Great Elder's prophecy where he is to meet the octopus.
