After all the Class cards have been captured, Illya and Miyu are once again ordered by Rin and Luvia to help them stabilize the Earth's pulse, that went haywire when they started capturing the Class Cards. However, something goes wrong after the ceremony. Illiya tries to protect everyone from the destructive explosion. But when the explosion is averted, and seemingly everyone is safe... Illiya finds a clone of herself sitting beside her.

What had happened? And how will Illiya get over this crisis?

The name is a word play on “2” and “Zwei”, which is German for “two”.
