Shirogane Clan

The is the puppet clan from Sunagakure appeared in Naruto: Uzumaki Chronicles 2. They are the principal antagonists of the game.

Background
According to the game, the Shirogane clan managed to live in the border of the Land of Wind. They were a small clan and have no skilled ninja. Trying to find a source of power to compensate that, they created puppet walkers. Wielding an army, they survived the Shinobi Wars. But a dark secret was exposed: to develop the puppet walkers, they abducted humans and made experimentation with them. The puppet walkers were outlawed, causing the clan start a rebellion against the Five Great Nations and being annihilated. They were the developers of the Master Puppet, the ultimate puppet walker who have power to destroy nations. But an unexpected event happened: it had its own will. And fearing its immense power, and the prospect that it the Puppet may one day rebel against its creators, the Shirogane sealed the Master Puppet away into the 5 Spirit Orbs. The Master Puppet was about to be revived during the rebellion, but the clan was squashed before they could do so. The last survivors hid the Spirit Orbs on the Five Great Nations swearing revenge, and disappeared.

The Shirogane were said to be comprised of ninja with meager skill compared to the other existing shinobi clans. However, they were highly proficient in the puppet-making arts, as it was their apparent inferiority that led to them developing the Puppet Walkers. These Puppet Walkers are superior to normal puppets in general since they can operate without a nearby puppeteer as they can be manipulated from a distance, and are capable of getting up after receiving multiple hits from the opposition. The Shirogane Three, a trio of the clan's survivors bent on reviving the Master Puppet, and use it as the trigger for clan's revival, were all skilled puppeteers, able to control their puppets in such a way that they could not only copy a target's appearance, but also near-accurately mimic the skills of their targets.
