History: He was on Kyo's team up until four years ago when the team dissolved when Kyo killed their sensei, Suzume Imai when she was being controlled by an enemy ninja.  Other than being on Team Suzume her history is mostly up to you.  Hayate was among the first that Kyo went to when he first learned of his Moudouken, and he wanted to tell the others about the power, though Kyo did not.  Eventually they told their sensei, and Kyo's fears weren't realized, even if people looked at him differently.

Village: Hidden Cloud

History: 14 years ago, Z was sent on a mission with several others from the hidden cloud village (his current village) where one of the ninjas cast a sleeping jutsu over the village, but a few were unaffected, including the 10 year old Kyo.  Z was there to dispatch of any resistance they faced while the others gathered the information.  Kyo was one of them, along with Kyo's mentor Eiji.  Kyo was nearly killed, stabbed with a sword through his chest, a sword that was left, and Kyo uses even today, a symbol of the man he has sworn vengeance against.  Z spared Kyo's life, but ended up killing Eiji on accident. 

Literally everything else about Z is up to you. That is all the details, other than the fact he uses the shadows, and he killed Eiji and nearly killed Kyo in an information raid.
