Obscuring Wind

This technique, invented by Nōsei, is designed specifically to evade and escape sensor type shinobi, or similar skilled individuals. In particular he used it when he fled Sunagakure due to the fact he had sensors in his team who may have pursued him. Obscuring Wind (曖昧風 Aimai-fū) operates as an extension of the hiden technique Ten'i no Kaze allowing the user to normalize their chakra emission to match the surrounding environment. Unfortunately, as this requires the user's internal chakra flow to be controlled it is impossible to maintain this technique while performing techniques that utilize anything beyond general chakra control.

Nōsei commonly employs this technique immediately after swirling wind around himself and quickly relocating. The sudden disappearance of his chakra signature prevents him from being tailed as easily and allows Nōsei to quickly throw off pursuers. Furthermore as this technique can be maintained for extended amounts of time without much drain on the user's stamina Nōsei can make seem as is he has appeared out of thin air to sensor types. This sudden appearance of his chakra signature in combination with his natural affinity has caused some people to believe that he is utilizing Jikūkan Ninjutsu. In Part II of his story Nōsei has shown that he can also hide the chakra signature of at least one other person with this technique, furthering its usage significantly.
