There appears to be no escape from the impending destruction of Earth. But at the end of the world, Zero Two decides that she will keep her promise, no matter what.

Hiro is left shattered with an unresponsive Zero Two, and the children struggle to come to terms with the aftermath. Left all alone to battle for their survival, what path will they choose to take?

While Hiro and Zero Two head to VIRM's home planet to defeat them, the rest of Squad 13 do their best to get life on Earth back on track.
