Illya and company ended their fierce battles with the Heroic Spirit residing within the 8th class card. They return to vacation mode in order to enjoy what little there is left of summer vacation to its fullest. However, everyday life as such is ever so easily broken down. Illya and company rush over to Mt. Enzo after some abnormalities, and before them appear unrealistic shadows. After a sudden battle, the skies sway. After all movements cease, Illya wakes up in a midwinter Fuyuki City - a parallel universe. It was the world where Miyu was born and raised in. Protecting everything that is precious, a battle to grant the magical girl's normal yet grand wish begins.
