Sand in Rain = A bad beach day [Kozai, Koroshi]

Kozai was kinda dissapointed. Now that they were going indoors, they had to climb up countless flights of stairs, which would definitely consume some stamina. "Welp, let's see how long we last against these stairs..." He would say.

While walking up the stairs Koroshi hears Kozai behind him, talking about how long they can last against the stairs, this making Koroshi stop in his tracks, and turn around to look at the man "I really hope you are joking, you are supposed to be a ninja, ninja's jump from tree to tree casually, and can fight for days on end. So how, I repeat how are stairs going to be a problem?" Koroshi says his voice filled with anger and aggravation, right after he is finished speaking however Koroshi turns back around and begins to walk up the stairs at a much faster pace, hopefully making Kozai fall over so he can drag him up.

Kozai hopped up after Koroshi at a quick pace, never losing focus of where they were going. "Well, it depends on how high these things go. If they really do go ALL the way to the top, I may not be able to take it as well as you do. After all, you're a kage, and I'm a mere chunin." As Kozai continued, he wondered if the person at the top was actually Near. Regardless, it would be useful for him to find out.

Koroshi scoffs at the man's comment, saying that h can't keep up because he is only a Chuunin "I know Genin's, and academy students that could climb this with ease, so as a Chuunin you should be able to do this no problem. Step up your training." Koroshi says, not even bothering to stop or turn around.

Kozai counter-scoffs at Koroshi's scoff. "With the opponents that Near puts me against, there hasn't been much reason for me to train up my stamina. I do massive loads of training weekly, and I mainly feel that my chakra has gotten stronger, and I've gotten faster as well. Why outlast your opponent when you can just finish him quickly?"

Not wanting to get in a scoff war with the man Koroshi simply sighs, stops walking and begins to speak "Because if you only train one part of your body you are leaving yourself open for attacks, for example you are already tired, and whining about climbing stairs, at any moment I could snap your neck, or throw you down the stairs" Koroshi says as he moves his right arm back, if Kozai doesn't do anything to stop this motion, then the earth ring press hard against his throat, causing him a lot of pain, as well as forcing his upper body backwards, making him lean over the steps, the only thing keeping him from falling being Koroshi, who has the other side of the leash in his right hand "What's your chakra and speed going to do to save you now?" Koroshi says in a cold tone.

Kozai was in much pain, and he knew that he would probably get wrecked by this kage in battle. "You're forgetting the difference in our strengths and battle experience, Kazekage. Keep in mind you're already at a much higher level than I am, so your attacks will obviously surpass my speed and chakra." With that, water would gush forth from the wall and form a solid staff of ice in Kozai's hand. "If I can't last for a while, I'll just have to use support, as derived from my own jutsu. I'm not ignorant, you know."

Still hearing nothing but excuses about their ranks, Koroshi sighs and pushes his right arm forward, bringing Kozai back on his step, and allowing him to stand normally, right after doing this however Koroshi begins to walk forward again "Well it doesn't matter, cause I don't plan on killing you at the moment, I still need you to find Near" Koroshi says still speaking in his cold tone.

Kozai smiles, of course Koroshi needs him. In the meantime, he needed a plan to survive. One of the leaders would most surely kill him, whether it be Near or Koroshi. Near for being a "traitor", Koroshi for being "useless". Oh well, they were about a quarter way up the skyscraper by now.

(Since nothing is happening I am skipping the walk up the stairs, and starting it as we are entering the room where the Kozai sensed the Chakra)

Koroshi arrives at the top of the skyscraper and begins to look around the room, once up there he pulls on his earth made leash, attempting to pull Kozai up the stairs and into the room while saying the following "So where is the high level of chakra coming from?"
