Peace operates within the Special Security Force as an explosives expert, frequently partnered with Hacker during high-stakes missions. A subtle romantic tension grows between them, left unacknowledged until her demise.

In the anime, she meets her end when Lucifer psychically drains her consciousness during a clash. The manga diverges, depicting her fate as she falls to Freya, a rival psychic adversary, who eliminates both her and Hacker in a joint assault.

Her narrative role varies: the anime positions her as a calm counterbalance to Angel’s sharp demeanor, a dynamic absent in the manga. Both iterations consistently frame her as a tactically adept agent, with her unwavering loyalty and unspoken bond with Hacker shaping her decisions until her final moments.

Her background prior to joining the Special Security Force and personal motivations beyond her duties remain undisclosed in official sources.
