Gunbuster, known in Japan as Aim for the Top! (トップをねらえ! Toppu o Nerae!), is a Japanese OVA anime series produced by Gainax released from 1988 to 1989.

In the very near future, a race of huge, insect-like aliens is discovered traveling the galaxy. These aliens seem dedicated to the eradication of the human species as it takes its first steps away from the solar system, and they are getting closer and closer to Earth. Humanity has responded by developing spacegoing battleships and giant fighting robots. These robots are piloted by the best and brightest of Earth’s youth, picked from training schools around the world. The story begins in the year 2023, not long after the first battles with the aliens, and centers on young Takaya Noriko.

The players of a virtual reality MMORPG, Sword Art Online, are trapped and fighting for their very lives. After it is announced that the only way to leave the game is by beating it, Kirito—a very powerful swordsman—and his friends take on a quest to free all the minds trapped in Aincrad.

Gunbuster: The story begins in the year 2023, not long after the first battles with the aliens, and centers on young Takaya Noriko.

Nonetheless, she has entered a training school. Through the series, Noriko, joined by the beautiful and talented Amano Kazumi, will fight to overcome the trauma of war, the doubts of her peers, and her own lack of confidence.

Made up of teenage pilots called Topless, and armed with quasi-humanoid weapons called Buster Machines, the Fraternity’s mission is to protect the people of the Solar System from attack by swarms of space monsters.
