Over the years, solitude and psychosis has turned Rin into more animal than anything else. Her prey is the only thing she lives for causing her to be abrupt, ill-tempered and more than a little hostile to those around her. She isn't deliberately rude, just cannot cope with people being around her.

Xirini has become an adept hunter, spending time with her mentor and training hard to reach his level of survival and tracking. Because of this, she will often fixate on an opponent and not rest until they are defeated. This often causes her to have a one track mind, as she will forgo rest and food when on the prowl.

Xirini has become an instrument of vengeance. She refuses to allow wrongdoing to persist and will go out of her way to stop anyone upsetting the status quo. She makes no distinction between friend and foe, only right and wrong. Because of her traumatic past, this belief system is deeply ingrained and nigh unshakeable.

Xirini has become cold, distant and calculating over the years. She does not enjoy doing things more than she absolutely has to in order to complete any given task. She will pursue her marks with eagerness and with extreme prejudice, but if pushed too far, she will also gladly disembowel them in front of their own children. She may even get the children after she finishes.

In combat, Rin transforms from a force for protection to an avenging angel. She enters combat with the intent to kill, not to capture or wound. Slugthrowers, rockets, grenades, Rin is a merchant of Death and will uses every option available to her. She ofttimes takes it to extremes refusing to quit the field until every last enemy combatant has been eliminated. She is fierce and a visage of death sealed within her armor.

Such extremes tends to lead to her endangering those around her as she dives headlong into battle and many other dangerous situations, such as traps.

Xirini’s presence of the field of battle has always meant only one thing to her - Victory. She is never willing to give ground and she detests losing. This has driven her to learn tactics and become a master at the art of killing without being present. Her own viciousness drives her to do things that others would view as deplorable and reprehensible.
