The voice does not have a required sex/gender, however you will need to be a teenager (AT LEAST) - which I'm hoping you are, regardless - to voice this character.

!!!!

The only lines you need to voice are your audition lines! Therefore, if your audition is accepted and you are cast as the character, your only needed recording will be the ones that you have left, unless I liked them but wanted the recording re-done. Thank you.
