Mangetsu Hōzuki

was a member of the Seven Ninja Swordsmen of the Mist and the older brother of Suigetsu Hōzuki.

Background
Both Mangetsu and Suigetsu trained with the intention of becoming members of the Seven Ninja Swordsmen of the Mist together. This dream acted as their motivation for them both to complete cruel missions day by day. Mangetsu was the first to become a member of the Seven Swordsmen, mastering all seven of the swords before his death. His premature death seemingly demotivated Suigetsu.

Appearance
Mangetsu has relatively long white hair and pointed, shark-like teeth; a trait that all known members of the Seven Ninja Swordsmen of the Mist possess. He wore an outfit very similar to the one his brother dons which consists of a dark sleeveless shirt and light colored pants. Like his brother he carried a water bottle in a belt around his waist and wore striped leg warmers typical of his village and a Forehead Protector. He wore bandages around his neck; another trait shared by the seven swordsmen. Overall both Mangetsu and Suigetsu bear great resemblance to one another.

Kenjutsu
Mangetsu was a very gifted and talented swordsman, having been accepted into the Seven Ninja Swordsmen of the Mist. According to his younger brother, Suigetsu, he was called the, which so happens to be the same nickname that Suigetsu himself shares. His skill, power and chakra were such that he was able to wield all seven blades of the swordsmen, including the notoriously picky blade: Samehada.

Nature Transformation
Little else is known about his jutsu, but he seems to be a Water Release user like his brother. He was shown using what appeared to be the Hydration Technique, a Hiden technique known by the brothers, against an Allied Shinobi Forces ninja.

Shinobi World War Arc
Mangetsu, as well as his fellow Swordsmen, were summoned by Kabuto Yakushi to fight Kakashi's division in the Land of Hot Water. After a combined attack from the shinobi forces proved fruitless against them, just destroying the coffins they came out of, Mangetsu summoned four of the seven swords for his fellow swordsmen. They then engaged in battle, and Mangetsu used his Hydration Technique to kill a shinobi.

Trivia

 * means "full moon", and is the Japanese word for the "chinese lantern" or "winter cherry", a fruit which resemble Chinese paper lanterns; like all members of the Seven Ninja Swordsmen, his surname is derived from a type of produce.
