[ Ren receives a doujin in which she is somehow a pureblood. Terrified of losing Serenity, she turns her into a vampire so that she can extend her life-- and keep her close. Because her life is so much more fragile, she keeps her inside a beautifully decorated birdcage, where Serenity is tragically beautiful and lonely, kept safe and isolated away from the rest of the cruel world. ]
