So, who exactly is Kuronuma Sawako? The following are discussions about who she really is, of course. Under this page presents a more factual-based information from the manga rather than my opinions. Most of the following discussed either contains little to no spoilers, so I think it is safe to say that you can venture through 80% of these pages without wrecking the plot.
