"Tonight you are a Cinderella, and when the clock strikes twelve, you will become a princess." It is 1914, and the continent of Uralia is on the brink of war as the aggressive Estmarch Empire prepares a grand ball to honor its prince, Kaito of House Shion. But that evening a lovely young beauty is sent to spend the evening with him... and take his life at the twelfth bell of midnight. Miku has known nothing but hardship and pain, sleeping within the cinders to keep warm. She has been given her first mission as an assassin, a "Cinderella", and she knows both her own fate and that of the prince. But when Prince Kaito turns out to be quite different from his tyrannical parents, Miku's training slips and she finds herself drawn to his kind heart. As the final bell tolls, Miku tries to change their fates... At midnight, the spells ends... and Cendrillon must flee as the fires of revolution consume everything in their path...

Ever since the day a blue-haired boy with wings saved Hatsune Miku's life, she's never stopped believing in the existence of more people like him - no matter how much people told her they didn't exist. Now in college with her dearest friends and "Vocaloids" bandmates, Megurine Luka and Kagamine Rin and Len, she's never given up hope on finding out what happened to the boy. When a blue-haired man turns up with strange gashes along his back, Miku immediately suspects the mysterious "Kaito" is connected to her mystery boy. Learning he has nowhere to go and nobody he can trust, Miku opens her home to the odd man, hoping that somehow he'll lead her to answers. But right now, all Kaito is leading Miku and her friends to is trouble as strange beings with wings are attacking Tsubasa City with dark magic known as "Noise". A strange winged swordsman named Gakupo quickly joins their number, himself corrupted by the power of Noise, as Miku, Kaito, and her friends find themselves drawn into remnants of an ancient war that threaten to destroy the world. Updates Saturdays at 12AM. Planned 20-chapter Vocaloid epic series!
