The Other Vayne is a physical manifestation of Vayne's powers as a Mana in Mana Khemia: Alchemists of Al-Revis. For the most part he exists solely in Vayne's mind, however he materializes in Heart's Prison to grant Vayne's wish to be alone. His sole reason for existing is to grant Vayne control over his power to grant wishes, and so his sole goal is granting Vayne's every wish, even his darkest desires. He also is a warped version of Vayne's personality, despite this he seems to be a playful and a bit sarcastic in his appearances. It is unknown if he has any attachments to people, since he is technically Vayne as well.
