I need help looking for a fic. It starts with inu, kagome, and sess. in their fathers cave when they are looking for tensiga. When kag pulls the soward out it pulse and inu and sess's father is in the soward (I think). He feels the power of kagome and uses her power to come alive again. Some how sess and his father mate kagome so they are equals in power. I cant remeber mush else. I hope this helps.
