Ivy of Lycana is a young shadow vampire. She arrives on the ship late with a wolf that actually is her brother Seymour. Seymour is the last known real heir of the Lycana clan and the one who turned Ivy into a shadow as he was lonely and wanted a big sister. Shadows are not allowed to attend the lessons of the Heirs and if someone found out, Ivy could be sentenced to death because of her secret.
She becomes close friends with Alisa and they do girls stuff together. When Alisa accidentally finds out that Ivy is a shadow vampire, she keeps the secret and tells no one – and the two girls become even closer.
