Hyouton • Souryuu Boufuusetsu is a Ninjutsu technique utilizing the Ice Element. After forming the needed handseals, Dotou will thrust his arms to send out twin black ether-like dragons to strike his opponent. As they flies through the air they will begin to turn, creating a large dark tornado. Note that the manga establishes Hyouton as a bloodline limit ability unique to Haku's family. This means this technique conflicts with established canon concerning who can do Ice Element techniques.
