People really wanted to see Nina loose, so made what they wanted. Other than that I think DOA female characters are shown loosing by other game characters frequently so I wanted to change the pace a little.
Here's the match choreography-
The crowd roared as Nina, the star of the Tekken tournament, stepped into the ring against Lisa, the famous fighter from the Dead or Alive competition. They both assumed their fighting stances, and the match began.
The two traded blows, with Lisa's kicks and punches matching Nina's punches and kicks. Nina tried to out-maneuver Lisa with her agility, but Lisa was too experienced to be outsmarted. The two continued to trade blows, each delivering punishing strikes, until Lisa landed a particularly hard kick to Nina's midsection, followed by a quick jab to the face.
Nina stumbled back, but quickly regained her footing and charged back at Lisa. The two continued to clash, lunging and dodging, neither showing signs of backing down.
Eventually, Lisa managed to gain the upper hand, using her superior grappling skills to take Nina down to the ground. Lisa quickly applied a submission hold and locked Nina into a Twister. Nina struggled to break free, but Lisa had her firmly in place and she could not escape.
Lisa's hold was too much for Nina, as Lisa leans back & stretches Nina more, Nina felt the stretch was too much, so much that it could leave Nina with a permanent spine injury. Nina had no other choice but to tap out in humiliation, crying in pain . Lisa had won the match, making Nina submit by breaking her spine and neck in the Twister lock.
The crowd erupted in cheers as the referee declared Lisa the victor, and the match was over. Lisa had proved herself to be the superior fighter, and Nina had been thoroughly defeated.
The credit for the models goes to their respective creators.
