It is the year 2356 AD, 189 years after a shockwave from a distant supernova decimated the Earth. Since that fateful day, humanity has begun training for a final mission to protect the planet from the inevitable oncoming 2nd shockwave - a mission whose failure means the annihilation of mankind. For Katase and her friends, their training at the foundation Stellvia is just the beginning of an adventure that could lead to saving the world, or seeing its end...
In the future, mankind is divided between two powers: Union, and Deague. For the young Sarah Werec, watching her dearest brother Ralph depart for the front lines of the war was a fate worse than death; for even if he were to survive, the 130 light year distance between them dictates that even if he were to return, she would be long since deceased. Thus, in an effort to see her brother again, Sarah sets out to become a pilot of the Strain – Union’s mecha force; but on the eve of reaching the first step to her goal, her only chance to succeed is stripped from her. Haunted by the many ghosts of her memories, Sarah must now endure an endless series of sacrifices as she struggles to discover the truth about her brother...
Both Stellvia and Strain are flight / space anime and feature chick pilots, space training schools and giggling teenagers. Although, Strain has a more adult-oriented storyline.
Both shows are hard science fiction exploring the future expansion of mankind into space. Both are aimed at seinen audiences and although Strain may appear more mature than Stellvia, with blood and deaths in every episode, both series have equally deep insight into human psychology when confronted with the unknown. Both shows also feature a headstrong, messianic main heroine and subtle yuri undertones.
When deadly asteroids threaten Earth, an elite team of interceptors--the Meteor Sweepers--are formed. Now, rookie pilot Honjou Mikaze and her three friends are caught up in tumultuous events that may expose a sinister conspiracy and put the fate of the world into the hands of a few young girls...
It's strange that no one has made this recommendation yet, as both are incredibly alike in the first half of each series. Stations train young pilots to protect the world from meteorites and to reach a higher goal. To protect humankind and venture further into space, the pilots must first survive these threats. Even the pacing is very similar; it is only in the second half of Stratos that these two anime start to differ. Stellvia stays the same, while Stratos becomes much more plot-heavy.
Somewhat similar story, aircraft and spacecraft, Stellvia is lighter while Stratos 4 has a far more serious undertone and more focus on character development.
Luna is an orphaned girl with dreams to attend a prestigious academy. After her celebrated acceptance, the class embarks on a field trip to see a world being colonized first-hand. However, in the middle of the journey, a storm overtakes the space vessel, causing a pod with Luna and a small group of students to be jettisoned into a gravity well -- stranding them on a planet far from home. Now, with monsters at every turn and supplies running short, the group of strangers must do the only thing they can -- survive.
Both series heavily feature teens and children living in a furturistic society. There is a heavy emphasis on teamwork and friendship in both. While Stellvia is geared towards a slightly older audience, the themes and characters are quite similar, and provide a very similar feel throughout the series.
