Professor Tachibana is impatient to test the robot's abilities again, but the girls won't let him get away with it so easily!

Professor Tachibana sends letters to the parents of the girls to get them to be pilots, but this leads to unforeseen (and dangerous?!) consequences!

A mysterious robbery occurs inside the robot! Who is the culprit?

Two male spies infiltrate the robot! Luckily, the girls catch them red-handed, but... they don't realize they're spies.

Five of the girls recall past events in hopes of understanding the way the robot works. But, they end up realizing different things from what they expected...

Stressed by different reasons, the girls reach an emotional climax that will lead to an unexpected confession.

Yoshida tells the girls about her life.

After listening to Yoshida's story, the girls have to make a choice that will change everything.

It's finally the moment of truth. What will the girls do?
