F1: Tempest Defense

The user creates a powerful air current that circles in front of them, creating a shield that blocks frontal attacks. The speed and intensity of the wind is great enough to stop anything it it comes into contact with. Most standard projectiles such as shuriken will bounce off of it, while chakra based attacks will either flow around it or - if they possess explosive power - detonate against it, leaving the user unharmed. A weakness of this technique is that it cannot guard from multiple directions, so the user is vulnerable to enemies quick enough to move around the shield and attack.
