Kozai's Sister!? O.o Meeting the River (Rin Yuki)

Kozai noted that the pond was a ready source of water, something that he was quite a fan of. Having the hidden mist technique available meant that he could use this water to cloak his movements, to a certain extent. Now that he was also able to cloak his chakra as well, this meant that as long as he could see through the mist, he could deliver attacks to the deadliest extent. Now, it appeared that he would once again be in the position of a teacher. Ah, Kozai loved to teach, not for the inflation of the ego that some people got out of it, but the fact that he loved to bring pockets of information together. Was it not he himself long ago that had put forth the theory that people could be visualized as isolated pockets of information to be brought together? The mere visualization of this gave Kozai a little bit of... nostalgia? No, not quite. It made him remember the days when his mind was occupied by more than one person; by the OTHER him. Well, those days were over, and Kozai had already moved on. Now, what jutsu to teach to Agito...? Kozai would have to ask him....
"So, you probably already know the water prison technique and hidden mist technique." Kozai would run through mentally his roster of jutsu... well, Agito probably had the chakra to learn this technique now. "In that case, I'll teach you Suidanha. This is a high-powered, high-precision attack that I used to kill the boy whose body is now in my lab." What a silly boy that missing ninja had been. Of course, Kozai was grateful that he had come to the Iwa gates... he had gained such valuable information. Mentally, Kozai pushed aside Echo's warning about his experiments... how dare that man suppress Kozai's progression.
At this point, he would look at Agito expectantly. "Well then? Are you ready? I'm sure there's no need for us to warm up or anything... Suidanha is a relatively simple jutsu, after all." Ah, and they had so much to discuss too.... Kozai got ready for what was to come. Suidanha was a technique that he found massively useful, as it could be used repeatedly without much drain on one's chakra... at least for him, a man who could sap chakra from even relatively strong ninja. Kozai would have to see...

Agito would shake out his arms and would nod as he listened to Kozai, this man had taught him so much, and even helped him to unlock potential within himself, Kozai was the man who helped to make Agito who he was today, going away from the path Near had set him on and making a new course for himself to walk, this was the man who taught him the Water Element, and how powerful it can be, this was the man that Agito showed off all his cool new jutsu to, like when he showed Kozai he had Mastered Water Dragon bullet and not just learned it, there was even a few more he thinks he could use to master in his list of things, but as of right now,he was about to learn a move Kozai said is called Sudihana, Agito listened to Kozai's words and as Kozai asked him if he was ready he would nod, and would already have his hands together and chakra flowing to them already to do as he beckoned, and Agito would ask really quick "Well Kozai, while we are doing this, is there something you would like to discuss, I am sure we can multi task if we set our minds to it" Agito smiled at Kozai, as this was Agito's way from letting this seem like a lesson in school and more like friends hanging out, showing stuff off, and even showing how they do this stuff, Agito would be watching Kozai's hands for hand signs to see what he needed to use to form this jutsu, Agito would be a little bit bouncy on his feet as he was ready to contine on as fast as possible, he wanted to learn all he could from Kozai, he knew in his heart, Kozai was going to be leaving soon, he heard Kozai once tell him recently he might have to go back in the ice chamber that he lost him to once already for some time, Agito did not want to go through that again, not without some sort of thing to help remember Kozai by
