Kiryū Kōzoku

This technique is Fuurin's masterpiece. It is a very useful technique that can be used in many situations. What the technique is that Fuurin merges with the air turning herself to air particles making her intangible. She completely merges with the surrounding atmosphere and turn into gas. In that form, Fuurin cannot be damaged and all techniques even chakra related ones are rendered useless. She is completely intangible and invisible as she united with the air around her. Fuurin can reform herself by collecting herself in a certain location. For instance, she can dematerialize in one place and then travel with the air currents and materialize in another place. The materialization is very brief and doesn't take time. The dematerialization and turning into gas can be done in an instant as she trained to do so. She can also pull off a partial dematerialization making certain parts of her body intangible. While being in gaseous form, she can move with enormous speed between air particles. This technique proved to be very useful for Fuurin, but it has a drawback. Fuurin can only use this technique for ten minutes if used continuously and in full transformation. If she sed partial transformation, she can push its use to half an hour. For example, she can dematerialize her arms for half an hour, but if she was to dematerialize her whole body, her maximum time would be ten minutes. She uses it cautiously as she dematerializes and then materializes in an instant in order to not waste the time. This technique is considered the strongest in her arsenal. The cool down of this technique is a solid six hours before it can be used again if the ten minutes were over.
