OH..This is a hard one. I found some I've read where Sesshoumaru may end up in the Modern Era, but it's not the main focus of the story. But here you go...
Chain Of Love by Chic Rated:MA
Autumn By Evelin Rated MAREAD ALL HER WARNINGS!! IT'S HELLA DARK!
A Debt to Be Paid By Rinku Rated:MA
This next list is what I call the "Time warping coma" Sesshoumaru makes it to Kagome's time via Coma, Curse, etc He's managed to 'survive' but the world is somehow new to him because he was removed from it somehow.
