She is a kirin solider, turned mercenary for hire.
Aqua was once part of the kirin army, serving as an expert in hunting and tracking, often deployed for mountain expeditions and operations, often as the leader of small units. Despite her expert track record in the army, she eventually severed ties with them due to unknown reasons, before moving to another part of Equestria, before offering her services up as a mercenary for hire.
Carries a silenced FAMAS assault rifle, silenced P90 SMG, and Desert Eagle handgun with her into battle.
Roze is often of a focused mindset, known to finish her job no matter what gets thrown in her way, and being unable to focus less on anything other then the mission until after it is done. She doesn't like to open herself up much to others, as she is very secretive about her past life and why she left the army. Despite this, she can still be a caring mare when she wants to, and she does have her own sense of morals.
She is bisexual, and she has been able to start a relationship up with a local cat obsessed bodyguard, called Meow Peow (Meow only knows parts of her history, and Roze is doing her best to make sure she doesn't know the full history of her, out of fear of hurting her)
