It has been nearly 1000 years since the magic has vanished from this world, and most people don’t remember magic anymore. Living in this world is the bright, energetic high school student Mangetsu Kohinata. While she is always looking at the bright side of things, deep inside she feels insecure. She has nothing for herself. She isn’t too good at studying or sports and really wants to find that one thing that only she can do.
The full moon was especially big one night when she met a girl with another moon-related name like hers – Fukami Ernesta Shingetsu. It was also when she encountered the magical dolls called Armanox. That night, the gears of Mangetsu’s fate started to move.
