"Right. Please do not try to take out my kneecaps. I heard that is a saying for you all. I don't want my kneecaps destroyed." Taking note of the serious look, Sadazane would swiftly turn around and dart into the forest. 

Humanity was usually the hunter and not the hunted. Well, there was one big exception, but anyone who managed to end up in that situation was usually dead. In a burst of speed, the Jihibiki ran into the forest as fast as he could, trying to put as many obstacles as he could between him and his chaser. Jumping up into the tree tops, he would hop from branch to branch as he was shown to do in the Academy, using his Chakra to push into his legs as soon as he stepped onto the next branch to launch himself forward and hopefully evade the Chunin for the moment.

"I promise nothing."

*The boy said as the Jihibiki ran off into the forest. He'd run off into the forest after them. His legs swinging as he ran, looking around for the Jihibiki. With his Byakugan, he could easily see where they were going, and how they decided to do it. He'd watch them go up into the trees, a grin growing on his face behind his dark blue mask as he ran through the forest passing by trees. He wasn't going at full speed, just at a speed to catch up, then match their pace for the time being. After a few seconds the boy would turn to a tree and run up it and begin to dash along the branches, launching himself forward to chase after the Jihibiki.*

Apparently, Masumi really did promise nothing. With him seeing the Chunin making a trajectory right for him as he looked back, Sadazane acted fast, instead of moving high onto the branch and leaping off of it, he moved down to catch it with his hand and drop back to the ground, hoping to run under thickets as he nearly moved on all fours like an animal to continue the hunt.

Coming up with a quick plan and not realizing the powers of the Byakugan, the Jihibiki I would make a quick right before jumping up into the trees again and hanging a hard left, attempting to criss cross and confuse his hunter.

*Masumi continued to chase after the bat ninja. Instead of returning to the ground, he opted to stay in the trees and jump along the branches like he was a ninja. He'd continue to stare at Sadazane as they ran, then criss crossed. The grin became a smirk after a few minutes. After the expression change he'd hop down off of the branch.*

*The boy continued to follow them into the forest, keeping his eyes directly on them. He was not confused by their tactics at all, he found it pretty funny. At this point he'd begin to speed up, slowly but surely catching up to the Jihibiki.*
