Kokoro (DEAD OR ALIVE)

Kokoro is a 17 year-old Japanese girl that uses the Bājíquán fighting style. Her mother, Miyako, was one of Fame Douglas' many mistresses (another being Helena's mother, Maria), and after Kokoro's birth, Miyako and her child moved to the country. Kokoro began training to be a geisha, but her heart was actually in both training to be a geisha and martial arts. She asked her mother if she could participate in the fourth Dead or Alive tournament, and she hesitantly accepted, but also says a statement indicating she could possibly meet someone of significance ("..blood is thicker than water"). After several rounds of the tournament, Kokoro meets Helena, who, unbeknownst to Kokoro, is her half-sister. However, Helena seems to recognize Kokoro and mentions Miyako before their fight. Kokoro's CG ending shows her returning home to pursue her geisha training once again, doing things like fan dancing and playing the shamisen and taiko drum.
Itagaki comments that Bājíquán was first used in Virtua Fighter series, which he calls the "origin of 3D fighting games." Virtua Fighter's main character, Akira Yuki, uses this fighting style, but Itagaki hopes to reproduce the martial art even more realistically in DOA4.
