Hiding with Camouflage Technique

The user controls the reflection of light around their body using chakra, causing their form, shadow, and even breathing to become invisible to the unaided eye. Because they perfectly blend in with their surroundings, the user can sneak up behind an enemy without being noticed. Since both their appearance and scent are camouflaged, their presence can only be revealed by the sounds they make. Dōjutsu like the Sharingan or Byakugan can also see through it.

Trivia

 * In the manga, Kakashi Hatake notes that he can't smell this technique's user. In the anime, Pakkun is able to sniff out Nagare despite his use of this technique.
