well i think that sango would be better off without miroku he doesnt deserve her or any other girl.well what about sesshomaru and that one girl from the panther demond tribe(blue hair) i think theres some tension between them even if they are old enemys... they look like they had a nasty break up but then he saves her so what about that.????
no sesshoumaru rescues songo and immediately fall for her and then helps her to be happy again and then marries her. they raise rin and have other kids in the future.
While this was all taking place inu yasha were off talking apparently she's pregnant and the daddy is inu yasha. so he makes peace with his brother. goes back to the future with kagome where he is honded for getting her pregnant and forced into a gushot wedding,. there first child is a girl that strangely resembles the miko who created the shikon jewel
