Shukiro Clan

The Shukiro clan was a migrant clan that was made officially a clan a few years after the Fourth Shinobi World War. They became a threat to the five hidden villages because of their thirst for power, leading to the Shukiro Massacre.

Founding
The Shukiro clan was created by Tanakuya Shukiro who was the son of two unknown Uzumaki that had escaped from by one of Orochimaru's hideouts between the Otogakure and Iwagakure. When Tanakuya was 25 years old he had been in horrible events, two that lead to his parent's deaths. He wanted to gain power and change the world, so he created the Shukiro Clan by stealing knowledge from orochimaru's hideouts, leading to a technique Tanakuya used inscribe the needed DNA for specific kekkei genkai to forcibly obtain them. He preached to people in other villages to recruit people to join his clan, promising a better world and giving many of them kekkei genkai by his DNA trick.

Shukiro Massacre
The five great nations found the Shukiro Clan as a threat to peace, so the current Hokage (Naruto) decided to learn of their intentions. Seeing that things were going terribly wrong in the clan, the Ryuun's father and mother devised a plan. They kidnapped several kids from Konoha and put them through the DNA simulations to embed Kekkei Genkai into them to save kekkei genkai because they thought it’d be a waste. They then asked to see Naruto for a meeting with several children from the village given kekkei genkai as a peace offering. In this meeting they told Naruto information that would lead to the Shukiro Massacre. At first Naruto didn't want to exterminate them, but to talk reason into them. But Ryuun's father insisted that it would be useless since they were all committed to gaining power to rule over the five great nations. Naruto set up shinobi from all five hidden villages for the ambush/massacre on the clan then walked up to the clan in person. Taiyō, who had become the leader of the clan after Masaaki defected, listened to what Naruto had to say to him about how the plan he had was wrong. Taiyō just simply laughed at what he had said and attacked Naruto, who had given the signal to exterminate the Shukiro Clan that day.
