Noriko Takaya has spent barely had a month at a training school for giant robots. The school announces they are going to select two candidates to go to the Exelion spaceship for the real missions to fight against an invading mech army. One of the choices is obviously the beautiful and leading senior Kazumi Amano, but somehow Noriko is selected for the second spot! The other girls get jealous that Noriko got the spot, suspecting it's because she was the daughter of the Admiral in a previous mission. School rival Reiko Kashihara feels that's totally wrong, and challenges Noriko to a duel.

Shock! Big-Sister and I are Going to be Pilots Together?!

Noriko and Kazumi arrive at the space fleet led by the space battleship Exelion. The girls get introduced to a hot shot female fighter named Jung Freud. During one of their mech training sessions, Jung spars with Kazumi, and end up in a part of the station where they discover one of the mechs of their enemy. Later on, Noriko and Kazumi are sent to partake in a special mission to investigate an object traveling at near light speed. With the laws of quantum physics and time dilation, the mission that would normally take just a few minutes will span several months. But they discover the object is the Lexion, the ship that Noriko's dad used to command.

They get into some minor trouble for being out, and as punishment, they have to polish the lenses for the laser cannon array. But then the Exelion gets a surprise fly-by by the enemy. The fleet goes after them for a large battle at Leaf 64. Toren offers to be Noriko's partner for the next battle, since she has fallen out of favor from Kazumi. But trouble arises as they get overwhelmed by the sweeping enemy.
