<Li> Star Butterfly ( voiced by Eden Sher ) -- The titular character is a magical princess from the dimension Mewni . On her 14th birthday , she is given the family heirloom , but after she causes a big accident , she is sent to the Earth dimension as a foreign exchange student . She then lives with the Diaz family . She enjoys exploring and being away from her parents and their pressure to make her into a perfect princess . Nefcy had originally designed Star as a fourth - grader obsessed with Sailor Moon and wanting to become a magical girl despite not having any powers . The design was initially just her with heart cheeks and the devil horns came later . By the time she pitched the idea to Disney she had made the character older , and an executive suggested she would have actual magical powers , leading to the current foreign exchange student concept . Nefcy says Star is very much like her , and that she has a lot of flaws and aspects of being a real girl . Star is Eden Sher 's first voice acting role . Sher describes Star as Disney 's first - ever kick - butt princess and identifies with her a lot : `` She 's always wrong . She 's always messing up . But at the same time , this character has such a good heart . Star is fiercely loyal when it comes to her friends and never backs down from a fight . There 's so much going on there . And that 's what makes this character so much fun to voice . '' </Li>
