Hiro and Yarashi time skip

During the time skip, Hiro and Yarashi spent most of their time either training or going on missions together. They developed a bond greater than just student/teacher. They became best friends, a duo that always did their missions together unless instructed otherwise. Yarashi trained Hiro so well that he was able to reach special jounin and learn many new techniques. Hiro also found 4 chakra rings on a mission they were doing but he could only wear 2 of them at a time without risking death. Wearing 3 of these rings would kill him in 5 minutes, wearing all 4 would kill him in 1 minute. Each ring has a different power, one greatly increases chakra, one greatly increases strength, one greatly increases speed, and one gives light regeneration abilities. 
 Yarashi had grown weary of his home in the land of lightning, His life mission of expanding the Uchiha clan seemed pointless, and the on-going war had given him stress about the Raikage, the Uchiha, and his dream in general. Regardless, Yarashi's son had grown to look up to his stressed father, at an age of 7. Yarashi seemed to be slightly inspired by his young boy, so much that he furthered the Rasengan to represent his bond with his son, and Hiro as well. On his free time, Yarashi had finished a new novel in his series, called "Romance formulas". Yarashi's books are becoming more known than his reputation as a ninja, but he can’t complain. Yarashi furthered his training of his endurance and chakra level strenuously during the war, he would have to prepare if he wanted to even look at his childhood friend the Raikage.

 Yarashi didn't go on missions so often; he spent more time training or studying laws of each village. Being a motivational speaker and a kind of Prosecutor was of more importance at the time....

Approved.
