Ghost Sweeper Yumi ~Reima no Gyakushuu~

A long time ago. There's a small village named Onigafuchi. The villagers have a secret; they are scapegoats for all the disaster, illness, curse and other misfortunes which hit the people in the capital. However, they have the spiritual tree that protects the village. It is called Reionjyu and is taken care of by the Reionji Family.

In modern days, Yumi Reionji, is the head of the family, she is a school girl and a ghost sweeper at the same time. One day, a spiritual tag on Reionjyu was taken off by someone. And that awakes many monsters who have been sleeping for a long time. They start attacking Yumi!
