Ayane is a kunoichi of the Mugen Tenshin clan and the current master of the clan's Hajinmon sect. She was the winner of the third Dead or Alive Tournament. Ayane is of petite height, with a slender and athletic frame and, despite being one of the youngest girls in the Dead or Alive series, she bears one of the largest busts out of all the women. Originally, she was designed with fair skin, a round face, with a small button-nose and wide eyes. As of Dead or Alive 5, her face is now oval-shaped and her eyes have been slightly narrowed but she doesn't appear too different from her former design.
