Bunny Girl is an anthropomorphic female rabbit featured in Operation 03: Lover Doll. Imprisoned as a sexual slave, she possesses white hair and brown eyes, with two nipple piercings connected by a thick bar.

During an escape attempt, another enslaved character named Cat Girl enters Bunny Girl's cell. Following a brief introduction, the two engage in sexual activity. This encounter is interrupted by a male captor who enters the room. He punishes Cat Girl for wandering away and subsequently rapes her.

Bunny Girl exhibits emotional dependency on her captor, displaying visible happiness upon receiving praise from him.
