She's actually the bouncer for the bar down this alley. While she's strong enough to handle anything that requires some muscle, most of the patrons find her adorable and will voluntarily quash any trouble before it starts, on her behalf.
When her shift is over, she usually strips from the waist up to air out after a long night, letting the breeze play across her lightly-furred skin...she's just as intimidating without her shirt, so she usually doesn't have anything to worry about.
