ノゾミカナエタマエ -Who Dreamed It?-

There is a book in the second-hand bookstore that can make all dreams come true. It opens way to a magnificent world full of mysteries and wonderful beings.
Three girls turn over the page with this world and become part of it. Black cat on the snow guides them into this fleeting dream. But this world needs protection as monster whispers in the center of this place.
