She is not good at studying and exercising She was longing for "something" that she could only do. The full moon evening where the night in the night sky was felt greatly burned. She encounters another girl with the name of the Moon, New Year Ernesta Deep Sea. It was also an encounter with a magical doll "Armanox". The gear of the fate of the full moon starts to move now, making a squeaky sound.
