Kimihiro Watanuki possesses the ability to see spirits and various other supernatural entities, a troublesome trait he deeply dislikes. One day, while being harassed by spirits on his way home, he is inexplicably drawn into a peculiar house. Inside, he meets Yuuko, a mysterious woman who claims she can remove his ability to see and attract these bothersome creatures—for a price. She requires him to work at her "store," which grants wishes to people, and so Watanuki's adventures through strange and wondrous events begin.
