Chinku Clan

The Chinku clan is a family of nin from Kirigakure and is one of the more infamous among the village.

History
The Chinku clan joined Kirgakure soon after it's creation and just before the first meeting of the five kage. The clan soon developed a long standing relationship with the leaders of the village and their anbu.

The height of their relationship with the mist came in the time of the fourth Mizukage, Yagura. They were the most... 'active' in the reinforcement of the village's infamous nick name. However, when Mei Terumi became the mizukage a rift began to form between the rutheless clan and the mist; as the mist's policies changed and its relations with other villages became restored, the rift grew wider and wider.

The final straw was during the Shinobi World War, when the final surviving member of the clan, Zokun Chinku, was caught stealing blood from allied soldiers and had even attempted to steal blood from Kakashi Hatake. From that point on the Chinku Clan became a rogue clan, hunted by the mist in order to make the final surviving member pay for his betrayal.

Abilities
The Chinku Clan proved to be well versed in medical ninjutsu, however their greatest achievement was in the creation of their signature technique; a special curse mark known as the Blood Binding Seal. The Chinku clan developed it in order to steal abilities from other nin, thus earning them their infamy and their nick name.
