Katana...Shuriken's sister.  She is completely covered in black, and has a
         rather long black ponytail that falls to he waist.  Like her
         brother, she uses her namesake to fight.  He prowess with the
         ninja sword, or katana, is second to none.  Unlike Shuriken, she
         lives for treasure and power, and kills whoever stands in her
         path.  She is responsible for her brother's scar, and the latter
         has been hunting her down for the past few years.  He wants to
         get her back to her clan, but she wants to kill him in the
         process.  To describe her, the term "ruthless" is an understatement.
