Dead or Alive 4
Kokoro is a 17 year-old geisha-in training. Her mother, Miyako, was one of Fame Douglas' many mistresses and after Kokoro's birth Miyako and her child moved to the country. Kokoro began training to be a geisha, but her heart was in both training to be a Geisha and martial arts. She asked her mother if she could participate in the 4th Dead or Alive Tournament, and she hesitantly accepted.
After several rounds of the tournament, Kokoro meets Helena who, unbeknownst to Kokoro, is her half-sister. Helena seems to recognize Kokoro however. Kokoro's CG ending shows her returning home to pursue her training once again.
