Background
Senkai was born seventeen years after the Fourth Shinobi World War to Tenten. Tenten was quite fond of her child, even for a parent, and began teaching the boy Bukijutsu at the very young age of four years old. The boy did not have much interest in this and would sometimes run away, quite fast, to play with others. Being younger, most of the other shinobi mistreated the boy, but he would run away quite quickly and strangely, none had the capability of outrunning the fellow despite his age. Naruto Uzumaki, the Hokage at that time, took note of the boy's speed and wanted to make him a great shinobi of Konoha. When he was seven, he was entered into the academy and was not a prodigy, though he was in close terms with such shinobi. He was soon after promoted and entered into a genin team, where he excelled to even greater heights, showing enless potential. After he was promoted to chunin, Naruto, who had been curious of the boy's skill when he was young, saw this potential, especially his speed, and gave the boy a special scroll which contained the instructions to perform invented by. Senkai trained for six years with the technique, perfecting it and gaining knowledge to every single mechanism of the Jutsu. This training was rigorous and often Senkai missed missions to train, purposely that is. Following his complete training and perfecting the technique in particular, Senkai performed missions more and was promoted to jonin at the age of sixteen. A year later, Senkai's fame with the technique went beyond borders of the land of fire, where enemy shinobi were ordered to flee upon seeing him.
