Stratos 4 (2004)

The attack of a swarm of comets finished, and the four girls, Mikaze, Karin, Ayamo, and Shizuha flew into the space riding in Stratos 4, which used to be Stratos Zero. They accidentally protected the Earth from the collision of the large comet Nigel 87. However, when they came back to Shimojijima Base, they began to spend days of training and part-time jobs as they used to do. Because the attack of the comets stopped for a while, they recovered normal lives. In these days, Chizuru and Annette, who are Comet Blasters, visited them. Note: This is a follow up for the series including two episodes, X-1 and X-2.
