i have that flora (temporary name is temporary) is an alien that lived out a sort of thumbelina kind of origin, but she's very much attached to earth and all its people so helping them comes somewhat easy to her. the only major challenge is that she doesn't particularly enjoy heroics or the fighting that comes with it so she'd be kind of useless and mostly reluctant unless they were in dire need or wanted her to bring the bandaids. that being said she'd probably have such an affection towards your girl, finding her eagerness and dedication so charming.
