Gunbuster & Diebuster

When alien nightmares attacked humanity's push into interstellar space, Noriko Takaya's father sacrificed himself to stop the advance. What he bought for mankind was time. Time to create a weapon capable of stopping the monsters once and for all. Now that weapon is nearly ready and a teenager Noriko is determined to be in the battle, though it's not until she models herself after the top pilot candidate Kazumi Amano that she discovers her own abilities. However, even as Noriko and Kazumi become both partners there's one aspect of this war that will affect them unlike any other: Pilots traveling faster than light experience time differently than those left on Earth. That means even if Noriko survives each battle, home will no longer be the same place!

This double feature comprises of "Gunbuster" and "Diebuster" (aka "Gunbuster 2") condensed into a single theatrical release told in two parts with a musical intermission in between. The 95-minute "Aim for the Top. Gunbuster" movie is a compilation of the original 6-episode Gunbuster OVA, where man first meets the insect aliens and builds fighting robots and huge battleships to combat them. Takaya Noriko and Amano Kazumi lead the fight, doing massive damage to the insect's world. The 100-minute "Aim for the Top 2. Diebuster" movie completes the series, with country girl Nono leading the "Topless" fighters to protect Earth from the invading insects.
