The Hōzuki clan (鬼灯一族, Hōzuki Ichizoku) is a group of ninja that originated from Kirigakure with the ability to turn their bodies into liquefied form.
The members of this clan possess the ability to turn their bodies into liquid form using the Hydrification Technique. This ability however seems to require that they stay hydrated at all times and as such at least two known members are known to carry water bottles around with them. Mangetsu and Suigetsu are very gifted swordsmen, and are known as the Second Coming of the Demon (鬼人の再来, Kijin no Sairai). It has also produced at least one Mizukage of the village.
