Previous Story:
Gen Fu is bringing back his legendary "Go-Ken" (Iron Fist) that he once swore that he will never use again because of its awesome destructive power. He needed to win the prize money from the "DOA2 World Tournament" so that he can afford the high medical fee for curing his sick grand-daughter Mei Lin.

DOA3 Story:
Thanks to the prize money obtained from the previous tournament, Gen Fu's grand-daughter Mei Lin, now grows better and better every day. One last surgery, however, is needed in order to cure her completely, and that will require a vast sum of money. To save the life of his grand-daughter, Gen Fu fights once again.
