Who doesn't know:

  There are actually two major schools of thought about Kasumi.  One is
that she is happily oblivious to the oddities that surround her.  The other
is that Kasumi is the one character (maybe Cologne) who actually knows
everything going on in Nerima but is much too polite to mention it.  

5. Ukyou (see the Cave of Lost love manga, I don't think she 
realizes)

  Not at that time, but is there any indication that she may know about
Ryouga in later episodes?  What about in the anime?
