The Serpent Breathing ( (へび) () (きゅう) Hebi no kokyū?) is a Breathing Style derived from the Water Breathing. The Serpent Breathing focuses on twisting and bending the sword like how a serpent slithers, the attacks are not direct and constantly meander which can ultimately strike anywhere. Since this technique is currently known to only be utilized by Obanai Iguro, it can only be used with a twisted blade that is similar in appearance to an Indonesian Kris Sword, with the sword's shape modeled into the bodily structure of a snake.
