Clans in Sunagakure (Non-Exhaustive List)
The Higashi Clan – This is one of the five noble families in Sunagakure, sometimes nicknamed the Kazekage clan or the Royal Clan, for having produced two out of the three Kazekage who ruled the hidden village. Strong and wise, the family possess the kekkei Gekkai 'Magnet Release', allowing them manipulation of sand and iron.
The Chikamatsu clan – This clan is one of the three noble families in Sunagakure, and perhaps the only one that is not bound by blood, but rather by bonds. They work in tandem and share their findings to promote and innovate puppet arts. Their heiress, Akira Chikamatsu, has recently become Commander of the Puppet Master Brigade, and thus became the youngest commander in History. Being the creator of the technique, Chikamatsu Hawn was the very first shinobi puppeteer, and as such he created the White Secret Technique: The Chikamatsu Collection of Ten Puppets. The puppets, reportedly strong enough to take down an entire castle, were designed to work together and, as such, were much more powerful than the standard puppet. His legacy has been passed down, the clan getting stronger and more versatile over the years.
Kiribati Clan – This clan is one of the three noble families in Sunagakure, their members famous for the Kekkei Gekkai they possess: the Kiribati pupils (Dojutsu), enabling them to wield powerful genjutsu they call 'Mirages', genjutsu that can trick the strongest shinobi and even armies. However, their yellow pupils are easily recognizable and using them cost a massive amount of chakra.
The Nokoma Clan – This clan has been producing the strongest ninjutsu specialists in Sunagakure. Known for its arts of Wind jutsu (futon) and fan arts, they are also very strong in politics and have always aimed to extend the three noble families to five, including them as part of the Sunagakure powerhouses.
Yagami Clan – Once a family branch of the Chikamatsu clan, one of the three noble families in Sunagakure, they were banished for their extensive use of poison and forbidden jutsu arts. They have perfected unique poison recipes and mixtures that have killed thousands of enemy shinobi over the years.
The Hoki Clan – A mysterious clan working on archives, history and information gathering. All of its members, be it babies or old men, are forbidden from revealing their true identity to anyone, always wearing recognizable black crow masks, and sand-coloured uniforms. They are loyal and obey the orders of the Sunagakure council, their existence being unique and mysterious, though their contributions and loyalty to the village are second to none.
The Furuse Clan – A small clan consisting of only a dozen family branches, with the rare Kekkei Gekkai of shapeshifting into monstrous scorpions capable of inflicting lethal poison and crippling damage through their massive, sharp claws.
The Aki Clan – Though not a noble family, the Aki Clan has proved its strength and loyalty over countless years, with their famous Kekkei Gekkai being the 'Scorch Release'. Pakura Aki has recently become one of the strongest Jonin in the village with skills that has surpassed the average Jonin level in spite of her young age.
