Yoimiya, like the rest of her family, is loved by the people of Inazuma City for the fireworks she creates. She is also loved by children due to her friendly hands-on approach with them, as she wishes to keep them happy so they don't have to deal with the harsh realities of Inazuma for the time being. Having very few worries of her own, she can also read peoples' hearts and can tell whether or not they're hiding something deep down.
