Mathilde is a piss poor bounty hunter. Unlike Syrina, Mathilde has yet to actually capture a single bounty on her own.
Well, that's not entirely true. The young woman has actually managed to apprehend a small handful of marks, but is such a soft touch that she's always let them go out of pity. The one bounty she actually collected on was killed by wolves and Mathilde happened upon the corpse a day later. Using her hacksaw she removed the man's hand as proof (especially since most of the rest of the body was unusable).
She's a short woman, with a soft heart and a peculiar stride -- smooth but awkward, as if slightly inebriated. She smells of lilac, which she thought would be a wonderful calling card... can you imagine the fear it would strike in a mark when they begin to smell it, knowing she's nearby and about to pounce? But again, she's never become infamous enough for it to matter.
She's heard of Syrina before, but is rather envious or her success.
