A Medley 半レ人, hanrejin?, lit. "Demi-Reyvateil"), is a term that was coined by Tyria as a partially serious joke to refer to Aoto's particular conditions. However, the term does have a more deep significance. A Medley is technically known inside the Archia Think Tank as an Active Fusion human, which is basically a human that has active Reyvateil genes, in contrast to the normal ones who have them suppressed, who together with the Third Generation Reyvateils are called Passive Fusion humans.
