Ryujin

 Ryujin was always seen alone or talking with his older brother ,Freezehud, but,it wasn't always the case. His parents were part of the elite group of Sandbu, elites ninjas who are working directly under the KazeKage. His father, Jinta Goto, was specialised in water release and could drown an enemy with his water in a couple of seconds and his mother, Ryuko Goto, was an expert on Wind release, especially with her fan, who could instantly chop heads off with a hit of her fan. As soon as he could walk, they were already starting to train him in order to make him an exceptional ninja. There were many times when Ryujin went to sleep with his body full of bruises because of his early training. Sadly, he was only 4 years old when ryujin saw his parents return from a dangerous mission with their squad in coffins,which caused him an enormous trauma which prevents him from having human emotions, except towards his older brother, Freezehud, and some people from his village, like his older brother's friend, Gaara.

Ryujin was 6 years of age when Sunagakure's Jonin realised his talent for Ninjutsu. When he entered the Ninja Academy, he was always the one who sleeps in the back of the class because it was too boring for him and he didn't want to socialize with his comrades. Soon enough, he discovered his affinity with Water Release and started immediately to train at it. Unlike his lazy behavior at school, he worked hard to excel in his ninjutsu. It was tough, but after hours of practice, he finally managed to master the Suiton.

Due to his lack of empathy and emotions, the higher-ups decided to let him at Genin rank, if they give him 3 students to teach them the ninja way, he could kill them  with cold blood if they didn’t listen to one of his order.

At age 19, him, Freezehud and Gaara were discussing strategy about a mission they've been assigned to by the KazeKage when they saw 4 powerful with oppressive aura coming from the Big desert of Sunagakure. It was none other than Lumy a.k.a budget brother, Mylu the better brother Lightning God Sparkzz and King Dona, ex-leader of the group Neo-Akatsuki who came back to demand a Pardon to Nauq, the KazeKage who was is charge during this time, and make the sand village stronger. As soon as they encounters those phenoms,  they took Ryujin, Freezehud and Gaara under their wings in order to train them to become experts.
