Donovan Baine

Donovan was featured in the Night Warriors anime OVA, as a wandering bounty hunter, often battling both his human and demon sides. A majority of the story was from Donovan's perspective, relatively making him the main character. Anita accompanies him, just as she does in the games. However, the plot is more compressed for the shorter window of the anime. Donovan cuts off the head of Anita's doll to awaken her anger. At one point, he welcomes a fatal wound, only to be saved by Hsien-Ko and her sister, Mei-Ling. After hearing the sister's sad past and realising their bleak future, Anita starts to cry.

Donovan then comments that she is almost complete, all she needs to do is awaken her happiness. (Source: Wikipedia)
