A swiss straight pull bolt action that SOMEHOW apparently fires faster than Semiautomatic rifles (She literally shoots faster than WA2000). That joke about the swiss replying to the Germans that if half a million of them invaded, the quarter million strong militia would shoot twice and go home? Someone sure took it to heart.

The downside of course is she debuffs her own accuracy when she does. This is not a problem during the day, and usually isn't a problem vs armored enemies, but it does become problematic when enemies at night start having dodge scores even while armoured, making her less good at those sorts of targets. In broad daylight though, go nuts.

Also a lot of artists seem to give her yandere qualities for whatever reason. Probably the knife.
