CLAMP PUT THOUGHT INTO THIS OK.
Even if Manga-chan’s storyline is (somehow) entirely consistent across the universe, the AUTHORS AREN’T.
Like. Consider that for a moment. Completely different people in completely different worlds all writing the same exact canonically matching plotline but in slightly different art styles.

WHOEVER THEY ARE.
