Uchuu Kuubo Blue Noah

In 2052, Earth experiences peace until the arrival of the Death Force, a group of aliens from a dying solar system seeking a new home. They attack Earth using a large satellite ship named Terror Star, attempting to transform the planet to suit their needs. Humanity's only hope lies with Colin Collins and a group of surviving students who operate a classified submersible ship capable of battling the invaders both underwater and in space. The first episode is approximately 96 minutes long, differing from the typical 24-minute format, and was later divided into four episodes for streaming platforms, home media, and most Western dubs.
