Zack won with DOA again. He was hoping to get along with Niki and to spend a great life together. However, Zack was troubled as he had too much sexual desire. He could not bring himself to approach his girlfriend, Niki, just to satisfy his sexual urge!

Because there's no love by doing so! He thought about the participants of DOA; Kasumi, Ayane and Hitomi. He attacked and humiliated Kasumi and Ayane then. But they escaped when the island sank. Hitomi did great in replace of Lei Fang. Zack decided to invite all three of them.
