There's no letter V in korean so often time it's written using the letter B in korean instead. 비비 (how it's spelled in the raws) can be interpreted as both Bibi and Vivi. Unless there's an official English translation of the name, I don't think we can know for sure. Also, I feel like in these fantasy setting, Vivi makes more sense!
um I don't know if anybody else did this but I understand Korean and from what I read I think her name is Bibi not Vivi but i mean.. you don't have to change it both are cute names haha
