Twin Blue Moons

At the beginning of the summer, Maya is brought to a remote forest area at her elder sister Nami's whim. Although discontented with the development at first, Maya's natural curiosity soon drives her to explore the new surroundings. Before long she has made a handful of new friends, among which are the forgetful girl at the lakeside, Lilia, and the eccentric alchemist, Kinoko.

Strange things start happening at nighttime, yet Maya's dreams feel more realistic than ever. Who are those tattooed girls that keep appearing before her time after time? Nami seems to know something, but it is as challenging as ever to learn the truth from her.
