Guardian

Twenty-four year old Yang Xiao Long was once one of the best Huntresses around. She traveled the world and made friends everywhere she went but something was always missing from her adventures. Now she works as a mercenary for hire, living a calmer life. When a Faunus family hires her to be their rebel daughter's body guard it seems like easy money. But when her ward turns out to be a familiar girl with golden eyes something sparks in Yang, giving her back the sense of adventure she thought she lost.

Blake Belladonna hates feeling cooped up in her own home and feels smothered by her over protective parents so she sneaks out at night, looking for adventure. Knowing they can't force their grown daughter to stay home, her parents hire her a body guard, much to Blake's annoyance. But when a familiar girl in a leather jacket with lilac eyes shows up for the job she finds that maybe having a body guard won't be as bad as she thought.
