Illya and Miyu are back for more magical girl action as they set out to stabilize the energy disruption caused by the Class Cards. But what starts out as a seemingly simple assignment quickly goes awry when Illya is suddenly split into two. Now, Illya’s dark counterpart is out for her life, and as the girls struggle to capture her, a new enemy appears to steal the Class Cards- and she means business!
The combined strength of Illya, Miyu, Kuro, Rin and Luvia might not be enough to contain the raw power of Bazett. As the mansion crumbles around them, a trump card is played that could spell total victory or ultimate defeat.
