"Nature Energy Cloak. Byakugan can't see me." Naruto chuckled as Neji was looking around in fear when Naruto disappeared.

Nature Energy is the perfect Dōjutsu fuckery. Nature Energy can't be seen by a non sage so imagine naruto using a Sage Cloak to turn invisible to the Hyuga's or Sasuke.

Think a boosted version of Jiraiya's Invisibility.
