Caroline develops a new latex armor suit similar to the ones used by the M.D.P girls. It is only one of a kind and when Caroline attempts to test it, she finds herself unable to move. The two deduce that they need someone with the required physical traits; Caroline initially wanted to have Yoshino use it, but she only designed it for herself. Caroline has the idea of getting Navy to help despite Towa's concerns. An unknown person watches them in the distance.
A few weeks later, the Ptolemaic base is attacked by the Rebel Army and everyone prepares to flee. Towa asks Caroline if she brought the Rebel Army here just so she could get tips on how to adjust the suit, just as Vita finds them. Knowing of her defection, Vita attempts to kill Caroline, but a girl stops her from doing so, revealing to be wearing the suit Caroline developed.
The girl, revealed to be Josette, overpowers Vita, who prepares to self destruct. Josette tells Caroline and Towa to run as she'll use herself to lessen the explosion, though Vita's self-destruct is halted when someone calls her and she withdraws. With the situation cleared, Josette apologizes to Caroline for taking the suit without permission and allows her to punish her any way she wants. Caroline, surprised someone had the physical strength and size to wear her suit, is awed and takes Josette to the lab to study her, with Towa quickly following them.
