LoL I guess that explains that XD I have a similar aged and similar personality character (all the way down to the survivor's guilt, I did make the tropiest most tragic backstory I could because anime themed game and also to make it as easy as possible for the first time GM to hook into XD), she at least subconsciously realises that she's not much help to anyone dead so she has a slightly more cautious approach.
that and being small she does need to figure out the quickest and most efficient ways to kill/disable people, while I did manage to get some amazing dice rolls that make her seem stronger than she is, she's the type that doesn't cope with taking hits but you have to be able to hit her, because of course she's mostly brawl/melee
