Iris Blanche

Iris is the last of the vampire tribe. She is a mysterious girl who lives within a tower on Whale Island. She sleeps during the day to stay out of the sun. Her other half is found much later on after further progress in the storyline. Though they first appear to be twins, later facts reveal that they were once one single person, but magic caused the single person to split into two separate people. They are Iris Noire and Iris Blanche.
