Angelica is THE main protagonist. She is who the story is about and has the most lines. Someone who is auditioning for this role should have versatility in their voice and should be regularly active as I may ask for some lines to be said/done in a different manner. 

^ Also, she has a funny last name, I don't know why I thought of it - but I hope it sticks haha.

Her voice should be bright, kind and full of personality. 

It doesn't need to be the classic Aphmau-ish voice, it can have your own vocal colour! (I used to be a huge Aphmau fan, so if you do have that genre of voice please do audition too haha)
