I was wondering if anyone else has considered the possibility that Kobato and Princess Sakura are the same person.
I realize that calling a character the "same person" in the interacting CLAMP universes might be the wrong expression. It might be more accurate to ask if Kobato and Princess Sakura are the same "soul" in slightly different people.
Anyhow, I came up with this idea when I realized that the beginning of Kobato's story (as revealed in later episodes oif that series) could easily be a continuation of the end of the Tsubasa series.
Of course, the way CLAMP ended Tsubasa series, adapting any story as a continuation might not be so difficult. With all the loose ends of Tsubasa left unresolved, a writer could say almost anything about what happened to some of the characters at the end of Tsubasa Shunraiki.
As with CLAMP's other series, Kobato and Tsubasa have some interactions betweem their respective characters. In one episode of Kobato, Syaoran, Kurogane, and Fei appear briefly as they travel between realities. Sakura is not with them when this happens. Syaoran tells Kobato that someone is waiting for him and he doesn't know when he'll see her again. They leave after a few days to continue their searching.
In fact it turns out that Kobato will eventually have someone waiting for her too - Fujimoto, the young man who works at the kindergarten. They have a mutual friend named Kohaku (some kind of angel) who says that some lovers repeat the process of meeting, falling in love, and parting for eternity. Talk about a loaded gun in the CLAMP interacting universes!
Well, that's the gist of my theory. Anyone else feel this way about Kobato and Princess Sakura?
(I know I didn't mention anything about the presence of "Chi" from Chobits in all three universes - as a human in two of them, and a Persacomm robot in Chobits. Granted that she's everywhere, I still couldn't think of any way she might be related to the possible common "soul" of Kobato and Princess Sakura).
Have a good one,
