Ryuji is 'Rasen'

I always thought that Ryuji (in Rasen) didn't want Reiko to die at all and really wanted to save her, but he wasn't too keen on letting Yoichi live because he regerted having children, and only really wanted to help Yoichi because its what Reiko wanted. There is this big theory that Ryuji was pulling the strings all along. That he was planning on helping Sadako. That he wanted to see the end all along. But Ryuji didn't want Reiko to die cause its obvious that he loves her, and she could come in handy with her diary. Cause I think that Reiko wrote that diary of her own freewill, thus creating the new and improved ring-virus. So when Ryuji died, he decided to help Sadako out but giving her a way into the world in return for coming back to life as well. In return however, she doesn't kill Reiko. Ryuji doesn't try to save Yoichi because apart from the fact that he doesn't like having his genes walking about he knows that Yoichi is more of a rival then an accomplice of Sadako. Seeing as the diary is already causing problems, like I said, Reiko could be useful. Still, Ryuji couldn't tell his own future so he didn't know how long it would take Sadako to be reborn and how long it would take for her to get round to having him cloned. In that time, Reiko dies from crashing a car when seeing Yoichi was dead. The wasn't part of the plan. So, I'd imagine Ryuji's a bit pissed off, but thankfully, he can deal with the diary when he gets his hands on it. Now seeing as Mai was the only woman who he was close to who he didn't care dying, he decided to leave clues and stuff to lead Ando and Mai together. Within time, Mai kicks the bucket and Sadako is born from her, and disguses herself as Mai to trick Ando. However when Ando finds out that Mai is really Sadako he freaks out and agrees to clone Ryuji in return for reserecting Takanori too. So now Ryuji is alive again, he can see the future again, and sees what will happen with Sadako's curse. It probably better that his family stay dead until further notice. There is that look on Ryuji's face at the end when Ando asks him what he'd seen cause he really did see more then what he said, what he sees we will never know. But he saw something that made him snigger a little. So maybe he's miss-leading Sadako a little bit, cause she can't see her own future, so Ryuji could turn around any moment and get rid of her now she's human. Cause if Sophie's theory is put to test and its Kaoru who is there on the beahc, tricking Sadako, Ando and everyone, then that means he has every intention of killing Sadako. Cause we have to remember that back when 'Rasen' was made, a 'Loop' was possible to come to light. So its only natural for us to believe that it's Kaoru there, pretending to be Ryuji then it would explain why he doesn't act like the real Ryuji when we see him on the beach. Besides, if Ryuji didn't want traces of his DNA in the world then that means that he'd rather die. In Ringu, Ryuji tells Reiko that maybe the three of them should all just die. So why would he want to come back to life if he wanted to die. So maybe all the tricks were done by Kaoru, I'm not sure.
