Emilia

An actress and a friend of Juliet. Pretty and youthful, she seems to be the cheerful and coquettish sort and invites Odin as Juliet to the Rose Ball. She appears to be one of the few amongst Juliet's circle of friends who doesn't know her real identity or gender, not even after the disastrous murder attempt on Lord Montague; she's forced to stay at William's house after lots of girls her age are arrested in an attempt to find Juliet. When she realizes that Odin was really Juliet, she panics due to Juliet's criminal status; William catches Ameilia and asserts that she is now an "accomplice" to Juliet. She later admits that she finds Juliet's alter ego, Odin, "cooler" as she can act well as a handsome man. (Source: Wikipedia)
