Fate/Kaleid liner Prisma☆Illya 2wei!

"The Class Cards, which Illya and Miyu had captured under the directions of Rin and Luvia and with the powers of Ruby and Sapphire, had been disturbing the ley lines in Fuyuki City while they were free. Once captured, they should have stopped affecting the area, and the ley lines should have naturally stabilised; however, two weeks had passed since the last card had been captured, with no sign of their recovery. Now, having received orders to fix the ley lines by forcing mana into them, Rin and Luvia once again draft Illya and Miyu into helping. The job is seemingly conducted without a hitch, but, as soon as they finish it, they find out that something went wrong, and the cave they're in begins to collapse. In the midst of the crisis, Illya tries to protect everyone; once faced with insurmountable danger, a power hidden within her awakens for the second time, and when this crisis is finally averted, she finds a clone of herself sitting beside her... and this clone of herself seems to be set on murdering her.
