Watch Stratos 4 Online

After successfully returning to Earth on the renovated Stratos 4, the four main characters are visited by the Comet Blasters Chizuru Kubo and Annette Kerry, who bring them a shocking video. Meanwhile, Orbital Station 7 is in serious trouble... This two-episode OVA comes between the first and second seasons.

A crisis is approaching, and meanwhile, the higher-ups are plotting behind everybody's backs. Plans of a massive comet interception mission involving both Comet Blasters and Meteor Sweepers' MiG-31MS and TSR-2MS are being prepared. But will the plan succeed? Is it tears of sorrow or laughter and joy that await the team of four beauties from Shimojijima Base?

The plot continues and while three new recruits come to the base for training, the whole team comes back to join the fun and defend the planet from outside or maybe inside enemies.

The show centres on the adventures and friendships of four Bishojo girls with a backdrop of a huge sky and the universe beyond. The year is 2xxx AD. Numerous comets have passed and detected in our solar system, and because of that, there are fears and unpredictable dangers that some of them may crashed upon the earth and will cause mass destruction on the planet. Therefore, as a part of Cosmic Crisis Management, mankind built a comet impact "cemetery" above earth's satellite orbit. This comet impact cemetery equipped with Space Shock Machines that will eliminate those comets before they can reach the earth. Those space shock machines are flown by female pilots, who also known as the Storm Troops, and are armed with special missiles to destroy incoming comets into small pieces. Those girls are soon to be known as Comet Blasters and are very popular among people on earth.On earth, in various places, many comet impact cemeteries were also made as second line of defence, so that in the event of large comet fragments passed the Comet Blasters, it can be destroyed by the Meteor Sweeper who fired special missiles from earth. At the same time, these comet impact cemeteries on earth provide training grounds where young pilots are trained to gain qualification as future Comet Blasters.
