七祇 紅莉

Akane's older twin sister, her 'change' has progressed a great deal more, resulting to her being semi-permanently confined to a special room in the center of the mansion.  She has a strong desire to drink blood and can draw both pleasure and sustenance from doing so.  Like all Devil Hunter twins, she is 'dragged along' by the emotions of her sister and does the same to the other.  In order to retain their mutual sanity, they must receive equivalent treatment from the one they love, lest they break down and go insane.

Possessor of the Ro of the Moon (along with her sister).  Unlike her younger sister, she doesn't even pretend to be 'normal', and her reactions are very straight and often childish.  She lured Sora into having sex with her when they were younger, giving him the misapprehension that he had raped Akane, as he is not aware they are twins.  She is not entirely sane, having been kept from Sora while her sister was allowed contact with him.
