Hakushin

Hakushin was a high level Buddhist priest who agreed to sacrefice himself to save his people from a pestalance in the area. He did so, but as he was waiting to die he began to hate his followers who prayed for his death in order that they may be saved. Naraku then convinces him to erect the barrier around Mount Hakurei and later his soul was free by Kikyo.Hakushins power was immense as he most likely is the most powerfull priest and is only rivalled by kagome and kikyo.He was able to create a barrier that no demon no matter how strong could not break as well as repel evil hearted people.The barrier he created was big enough to cover a whole mountain and its power can still affect people who are miles away and miroku and sango could not break it if it were not for mirokus wind tunnel which still had trouble during there fight with hakushin.During his fight with sango and miroku he was able to easily overpower them even calling miroku's abilities being that of a novice even though miroku is a powerfull priest him self shows that hakushin is extremely strong.
