Koukaku Fudou Senki Robo-san

Professor Tachibana finds eight girls hanging out inside the giant robot that saved the earth, and suddenly, it starts to move!

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.

Eight beautiful and professional women go inside the robot in hopes to be the actual pilots, but certain eight girls have the exact opposite in mind.
