Ai, Neiru, Rika, and Momoe are quickly becoming close friends as they continue to protect Eggs. But as they grow closer, questions pile up and tensions rise.

The girls are surprised when Neiru invites them all to her house, and even more surprised to find out that she lives at her company. Is Neiru ready to be open about her situation, and how will the others take it if she is?

The girls realize that there's more waiting for them at the end of missions than they bargained for. As doubts pile up and tensions rise, Ura-Acca decides to tell Ai his story.

Friendships are tested as Ai and Neiru realize how much "victory" has cost Rika and Momoe. Ai decides to fight again in spite of what she's learned, but the girl who emerges from her Egg this time may be more than she bargained for.
