i had read this a long time ago and i fell in love with it. in this story sesshoumaru is three different person with different eye colour ( blue , golden and green )and different personalities ( one that it's stuck on a killer mode , the actual sesshoumaru and a kind one.
Kagome finds about this from a mysterious biography of Sesshoumaru. Oh and also sesshoumaru kills her friend, Sango and when she is about to be killed ( or she was killed (can't remember ) ) she meets the sesshoumaru with blue eyes that was in hell but he did escape because he won some challenge. Also the he doesn't know a think about Inuyasha , he didn't even knew he had a brother (halfbrother), and he wasn't raised in a castle but in a village ...



I know that the details are ambiguous , but if you know this story please tell me !

That's Testament Book 1: In The Beginning by Deaville RATED MA. One of my favorites! There's a sequel to this story too, which you can find on Deaville's author page.

Thank you !

No problem!
