クローバー図書館の住人たち

On the corner of a modern town, on higher ground atop a hill is a Western building, old as though it were left behind by time. Closed for many years, it is a private library called "Clover Library". Loving books from a young age, Aikawa Chihiro wishes to one day have a job involving books. She then earns the job of a live-in custodian of the Clover Library.

With a look like that of on old photograph, strange and impossible things occur there, one after another.

The sense of being gazed upon, even though nobody should be inside. Books that moved before one knew it. Large, large shadows peering through the window. Finally, at night, people that come out of nowhere who call themselves "frequenters since the olden days".
