Nenene's editor Lee actually works for Dokusensha and takes her so that she can write Dokusensha's stories.  The three sisters are helpless to stop this and, in addition, they are no longer employed as her bodyguards.  Anita, Maggie and Michelle take a Three Sisters Vote anyway to determine if they should rescue Nenene.  Of course, she's their friend and it's unanimous and they set out for the Dokusensha building.
