I'm pretty sure we can all agree that Naruto is using RSM in the boruto movie and gaiden, but before that he could only use Kyuubi chakra mode during the last, which was two years after his fight with Sasuke.
How it exactly did he go from having Kyuubi mode to regaining his RSM by the time he became hokage?
