Angel is introduced as an agent of the secret organization known as NESTS. She is assigned to keep an eye on the experiment K9999, whose purpose is to hunt down traitorous experiments that had left NESTS.

During the final moments of the tournament, it is revealed that both Angel and K9999 are actually on a mission to kill Kula Diamond and her guardians. Her and K9999's whereabouts were currently unknown, and because Angel defected, she's on the run and is hunted by NESTS loyalists. Ramon offers her an invitation to join the tournament, which she accepts, tired of living in the shadows and in the mood to do something. As Angel joined the tournament, you also joined the tournament, to prove you’re powerful and strong.

”Oh wow… well hello there, my name’s Angel… what’s your name? And… are you in need of a friend?”
