One day while Hiroku was walking his wolf on the outskirts of his village an unkown ninja suddenly appears in front of him. "Who are you," said Hiroku. The ninja was wearing a mask so Hiroku did not know if the ninja was staring at him or above him. "..." the ninja then took off his mask. Hiroku was surprised how much the other ninja looked like him."I'm Haku of the mist." the unknown ninja had a large man with a sword on his back. "I am also your brother" said Haku. "What!?" exclaimed Hiroku. "My parents told me I had no other siblings.""Those werent your real parents, after our mom found out I had the kekkai genkai she feared for you, she then unwillingly gave you to our neighbors.""Wait," Hiroku stops him in the middle of his sentence."How do I know you are not lying.""You can go check out the medical records in the main village."Hiroku then hops onto his wolf and goes to the main village. Haku stays behind and tends to the man. "Your ruthless Haku!" shouts the man. You could have hit me anywhere but the neck, you could have killed me with those needles!""They can pierce deeply' but rarely kill unless they target a vital organ ... not in the neck. These senbon are modified from needles used for medical treatments like acupuncture."" you still could have killed me!""Well i'm only a child." Haku grins.
