An actress who is friends with Juliet, Ameilia is described as being pretty and youthful, with a cheerful and coquettish demeanor. She invites Odin to the Rose Ball under the guise of Juliet. Despite knowing that she is not actually Juliet, Ameilia does not seem to realize this after the attempted murder on Lord Montague. After the arrests of many girls her age in an attempt to find Juliet, Ameilia is forced to stay at William's house. When she discovers that Odin is actually Juliet, she becomes panicked due to Juliet's criminal status. William then asserts that Ameilia is now an "accomplice" to Juliet. Later, Ameilia admits that she finds Odin, or Juliet's alter ego, to be "cooler" because he can act well as a handsome man.
