"And he went through so many too, just how dense are you?" -> Lol, I feel like this is a double pun and it's great. 

They turn me around and it becomes painfully clear, literally. The pain hit me like a brick wall. "ow~"
I could't believe it. "Seven?" Kyri stood over me smiling. "Yep!" I shot up. "How!?" -> I am confused by this. Why is he in pain? Did he only turn around or did they throw him again? Also, what does he mean by seven? Seven what?

"hard enough to give my face an express ride straight to the floor." -> Haha, nice. 

This Is The Best Day Ever! Heh, shut Sinya too, she looks like a zombie. "KYRI!!" "What?" Damn, she cut me off. "Why Are You Kissing Him!? Weren't You Just Pissed At Him!?" I don't get it either, but hey, I'm not complaining. "Just wait for it." Wait? for what. "For What, Exactly?" That was amazing either way. "That." I feel like I'm walking on air...
"I'm going to die. Arn't I?" Kyri said something but, I was way to high up to hear it. Well it was a good run while it lasted. Goodbye everyone, this probably wont even leave something recognizable about me, Skull? Flat. Teeth? Shattered. I'll just be a bloody smear on the pavement.
"You sleeping or something?" I peek for a second. "I'm trying to make peace with myself." So rude, now where was I? Oh yeah, bloody smear. Why are you doing that?" Really? "Because I'm about to fall to my death, now leave me alone."
There was a bit of laughter, why were they all laughing. How did they even get up here? "Whats so funny!?" I got up, ready to knock some heads. Kick butt and take names! I was going to- "It's just that it's going to be hard to fall to your death, when you're already on the ground. What are you going to do? Fall up?" The room was full of laughter again.
"Fuck You!" Man I was blazing."Oh shit." And they look like they were going to piss themselves. "Heh, Yeah Thats Right! Piss Off!" I knew Kyri didn't like it when I was mad, but these guys, man they look genuinely afraid. "Look calm down dude, we were just having fun. No need to go hyper-nova." Hyper-nova, huh? "What do you mean?" Sounds badass. "Look at yourself."

        -> All of this was hard to follow. I'd still suggest having dialogue on separate lines and make it clearer as to when he's talking and thinking. Were they talking in his mind there at the end? Was he just imagining that he was rising up? And why did Kyri say she will probably die?

Just some things to consider. This part was actually pretty funny; I love the interactions between all three characters. I like how even though Kyri and her sister are twins, they each have a distinct personality and are not clones of each other (I've seen that in other books, lol.) Great job, keep me posted!
