Kidnapped! Naruto's Hot Spring Adventure!

Synopsis
On their way back to Konoha, Tsunade suggests the group to take a break at a hot spring town for a day. At first, Jiraiya rejects but after Tsunade hoaxes him that there will be pretty women out there, Jiraiya agrees. During this conversation, two strangers spy on the group. During their stay, Naruto Uzumaki learns that the two are Senta and Bunzō (two members of the Akagi gang) who cannot return home unless they collect Tsunade's debts, and attempts to help the two. Shizune, fearing that Tsunade's debts, if exposed, would jeopardise her chances of becoming Hokage, disguises herself as Tsunade to stop Naruto, but neither of them realises that the debt had already been paid a time ago.
