Jade Harley is one of John's closest friends and a major role in Homestuck. She's friendly and sweet, and I expect her voice to have a light and feathery quality-most preferably, a light Mezzo, but a soprano could easily be accepted! (Jade's more of a mixer than a belter, so I don't expect heavy belting, but a nice consistent mix would be lovely to hear.)

SOME ROLES TO BASE HER VOICE OFF OF (And song inspirations!) ARE:

Elle Woods, Legally Blonde--[Legally Blonde, So Much Better]
Wendla Bergman, Spring Awakening--[Mama Who Bore Me, Whispering]
Kate Monster, Ave. Q--[A Fine, Fine, Line, Mix Tape]
