Now, it's been a while since I've read this fic so I can't remember if it turns into a SessxKag or not.
What I remember about the fic is that Sesshoumaru is taken to another dimension by a demon more powerful than himself in order to protect Rin (Rin ends up in the modern era for protection). Inuyasha finds out and goes to save Sesshoumaru. Which he does of course. I could have sworn the title was "The Price of Love" but I was wrong. Help please?
