They say when a soul leaves life before it's supposed to it throws off the universe, after all, humans and demons alike where not programmed to end their own lives. So when someone dies of their own doing, it not only ends the souls time, but it effects every soul that has a life string attached to it.
This is not to confused with sacrifices, when someone dies protecting something it was most Likely meant to be, what they were sent on earth to do.
But Iunyasha did not die protecting anyone. Inuyasha walked into hell with open willing arms, effectively ending his life and cutting off his soul to its life way before its time.
His soul screamed and the universe became unsettled. It tried to re write its self, it tried to re write the lives of the people who had life stings attached to him, but, no matter how many time it tried to re write, it could not find a end.
His friends could not grasp it, it didn't feel right, it made all their lives seem in slow motion, the days seemed longer, the nights seemed longer and they found that they could not even mourn, even his brother felt robbed.
life could can not go on with out a end to the beginning, and so the Great Kamis above decided soul for a soul. They could not send Inuyasha back for he was in hell and the kamis have no power there, the only place they could not step foot. So they called forth the closes thing, his very own blood, they called forth his sire, the great and terrible Lord of the West, Lord Touga Iuntasio, from the after life, and sent him back to life, giving him his soul once more and his flesh to his bone, he once again breathed.
"I am alive"
