The Haunted Bookstore - Gateway to a Parallel Universe (Light Novel) Vol. 5 (novel)

Kaori and Suimei have finally realised how they feel about each other, but their love will have to wait - the bookstore is in terrible danger. One day, a fox spirit called Hakuzousu storms in, screaming, "The spirit realm has no use for such an unscrupulous bookstore!" He blames his daughter's love for a human on the influence of human books. Shinonome can't just shrug off such an insult, and Kaori fears that a fight between her father and the fox will reduce the store to ashes.

So, she sets out to seek help from the Three Great Tanukis of Japan to quell Hakuzousu's anger, but whether they'll answer her call is another story...
