I can't remember the name or author but the fic has Sess and Kag mate, they have Rin and Shippo and Miroku with them. Inuyasha and Sango went some where else (they aren't a couple.) Kohaku is with Sango but he wants to be with Sess. Bokunseno brings back Byuakya, Kagura and Kanna and later Touga who save Byuakya life. Moth demons are in here and Touga meets his life-mate Elizabeth near the end. I hope I gave enough info, there are other pieces I can remember, the story is completed and rated M or MA.

In this fan fic Kagome and Sesshoumaru are mated, Rin and Shippo also Miroku are part of the pack. Kohaku joins and the Byuakya(sp?) joins. Touga comes back, he ends up saving Byuakya. Kagura and Kanna were brought back also but were living in a small home, that Touga or Sess owns. I also remember Moth Demons helping Kagome. I hopes this helps with finding this story.

Pretty sure this is Wandering Ways by Marina Lenore
