Run through of Kokoro's Story Mode.
At 17 years old, Kokoro started to focus more on her Ba Ji Quan training, and asked her mother if she could participate in the fourth Dead or Alive Tournament. While Miyako was not happy about her daughter's choice, she hesitantly gave her permission, but warned Kokoro that she might not necessarily like what would come of it.
During one of her initial matches, Kokoro faced the drunken master Brad Wong, who seemed to like her. Kokoro, however, was put off by the drunk and vehement fighter, and declined his offer for a drink. After several rounds of the tournament, Kokoro met Helena. Unaware that they were related, Kokoro was surprised when Helena recognised her as Miyako's daughter before their fight. It is then that Helena mentions that Kokoro should learn her fighting technique, Pi Qua Quan.
