Hanzo would not answer right away, moving closer until he was about right in front of Jobu. "Ryota Hanzo. Are we here to exchange names, or are we here to train?" Hanzo would reply rudely. 

The night was perfect for the task at hand, as Hanzo was interested in training his vision to help with his shurikenjutsu. "I've come here to get stronger, if you want to as well, just tell me what you would like to practice."

Jobu would withhold the urge to sigh deeply. This was what he wanted for the most part, so he couldn't really complain. *"Well, I've got really bad chakra tendencies."* Jobu would start to say, walking towards Hanzo's hiding spot and placing one foot onto its surface. *"How about this; I climb this thing, you try and stop me?"*

As he would finish, he began applying his chakra into his feet, but was barely able to get his footing as it was. It would be a challenge for certain, if he were to try and climb the object while being already terrible in that area of expertise. 

Nevertheless, he didn't let those concerns surface, as he was determined to finally overcome this hurdle he had been struggling with in the academy. Perhaps some much needed stakes would help him learn faster.

Hanzo wouldn't respond with words anymore, taking shurikens from his sides and placing them between his fingers. Taking a few steps back to get into a striking distance, he would prepare his throwing arm as Jobu would try and climb the broken tree he had hid behind.

Someone else may have hesitated, but Hanzo was no such person. He came here to train and now he was going to do so. If Jobu was asking to to be injured, Hanzo was not going to stop him.

But, Hanzo was also interested in applying his training to his vision. So to achieve this, he took his other hand and covered one eye. While it was night already, it would make the throwing of the shurikens more random and could probably make it easier to dodge.

He wasn't planning on going full strength either, cold as he would appear. He was not trying to kill Jobu. Instead, he would wind his arm back at about half strength, throwing three shurikens all at once in Jobu's direction as he started climbing.

While Jobu had told Hanzo explicitly to attack him, for some reason, he wasn't expecting Hanzo to do it so readily. He figured that Hanzo would at least allow him to get his footing on the tree. Nevertheless, Jobu got about a third of the way up the tree before the shurikens came flying at him, causing him to lose his balance completely.

Stranded in midair with no way to block any of the shurikens being hurled at them, all he could do was shield his eyes as he would hope that they would harmlessly pass by him. With Hanzo's one opened eye, but decent shurikenjutsu, it was safe to say that despite his self-imposed handicap, it was still a loss for Jobu.

The first of the shurikens spun towards him, going wide because of him falling back towards the earth. The second, he didn't have any chance to defend against, as it lacerated Jobu's arm. The last one, also went wide, likely due to the impaired vision, but Jobu couldn't really say for sure. He couldn't see anything.

Hitting the ground with a thud, he seethed in pain with the small gash on his arm. *"Man, that stings!*" Jobu would stare at Hanzo with a look of contempt.
Victor
Hanzo's expression would stay the same, even with the hateful stare down Jobu was giving him. He would remove his hand covering his eye, saying nothing as he went to retrieve his shurikens, the one at Jobu's feet as well. Could not afford to let them go to waste, that is.

Hanzo's cold eyes would meet Jobu's scornful ones. "Just remember that you asked for this, Otoki. I held back that time, just know that." He would say, getting his shurikens between his fingers again and moving away 10 yards.
