After a certain period of time, they decided to grant the almighty authority onto a human shrine maiden, and entrusted her the duty of maintaining the barrier. And so the system is completed.The Great Hakurei's Barrier is the most important barrier that separates Gensoukyou from the Outside world.Incredible! So this is the Great Hakurei's Barrier!I have already read such a thing in the book.For having control over the Great Barrier would be the same as controlling the whole of Gensoukyou itself.The Great Hakurei's Barrier was first created by The Great Youkais of Gensoukyou, but then they were faced with a problem on who would maintain it.To begin with, it was first created about 130 years ago...Even I know that this barrier collects spiritual power from all over Gensoukyou!
