I don't think she needs to reach across the universes for it. While you have not yet revealed her backstory (and please don't! I'd rather find out in story), it's clear that she had the courage to run from a bad situation and from her family, leaving behind all she's known. That is bravery in and of itself! She may not be the sword-slinger, gun-toting version of herself in the other realities, but as a writer I do not doubt that this Kijani has courage. In fact, I think she has more courage than her counterparts. You see, it's one thing to be brave when you know how to use a gun or a blade, or when you have powers or abilities beyond those of 'mortal men' (and women, obviously.) Far braver is the person without such skills or knowledge but who still stands his/her ground despite knocking knees and heart gripping terror.
