The Hōzuki Clan (鬼灯一族, Hōzuki Ichizoku) is a group of ninja that settled in Kirigakure after the ending of the Warring States Period. Members of this clan have the ability to turn their bodies into a liquefied state.
The members of this clan possess the ability to turn their bodies into liquid state 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.
The name "Hōzuki" means "Demon Lantern" (鬼灯), which is the Japanese word for the Chinese Lantern, a plant bearing fruit which resemble Chinese paper lanterns. Like most surnames of members of the Seven Swordsmen of the Mist, it is based on a type of produce.
All known members' name ends with getsu (月), which means "moon".
