In the early 21st century, insectoid organisms are invading the galaxy, searching for new stars to house their young. Mankind's only defense lies with space cadets such as Takaya Noriko, daughter of a celebrated admiral killed in battle, and Amano Kazumi, the top of her class. With their skill and the power of the mecha known as GunBuster, the girls must help fight to protect the galaxy from total annihilation...
What do you do if humanity is threatened by hostile aliens hell bent on eradicating us? You pilot a giant robot and fight them until death of course! This idea forms the driving force behind Muv-Luv Alternative: Total Eclipse and Gunbuster.
To combat an alien threat, both these series involve protagonists as part of military units, piloting giant robots as a frontline response. Our pilots also undergo various drills and training to become effective fighters.
Cue action set pieces, and you're set for some carnage! Though Gunbuster is an older show, it is a cult classic and a must watch for any fan of mecha shows. So if Muv-Luv Alternative: Total Eclipse had you salivating for more epic alien apocalypse action, then make sure you check out Gunbuster!
In the early 21st century, the emergence of an incurable condition known as B-cell growth led some of the affected to become "Sleepers" - people put under stasis until a cure could be found. Yuji Kaido is one such Sleeper who awakens, several decades later, to a horrifying new reality. Giant bugs known as Blue have invaded the Earth, eating everything - and everyone - in sight. Now, all Yuji can do is escape from the city with the ones who saved him from his inevitable death, and make their way towards Second Earth: mankind's new home in space.
While Blue gender isn't a mech anime, both shows seem to have the same feeling of hopelesness in the face of overhelming threat. Both feature a vicious type of aliens invading earth and massacring the humanity. Both got pretty heavy theme, not only in terms of visual gore, but also psychological impact.
In the year 1945, the most terrible creatures in existence visited the earth: bug-like entities soon to be known as Phantom Beasts. In that time of peril, mankind joined together to expel the threat, only to find that conventional weapons were useless and further damaged the earth. It is now 1999, and the student-wide draft has changed the lives of thousands of teenagers across Japan. While unwillingly fighting in an endless war that started before their births, one group of friends will experience the tragedy of death and the bittersweet joy of love as they struggle to survive.
These animes really resemble each other in many aspects. There's fictional past, where aliens have overtaken earth and people lost most of their countries, but they're still fighting to get it all back by military force in form of mechas. Even the plot is set in military environment and main subject is character's thinking. Because Muv-Luv is still ongoing, I can't say, if in case of Muv-Luv will be any romance like in Gunparade March, it doesn't seem this way, but it's not impossible.
In the not-too-distant future, Earth was attacked by mysterious beings and before long over a third of the world's population was destroyed. Even after bringing to bear its full, united military strength, humanity was unable to repel the assailants and forced into using weapons of mass destruction. This was successful, but the war and its conclusion resulted in the deaths of a crushing percentage of all fighting-aged males, and Antarctica being melted, causing much of the Earth's land to sink underwater. Years later, three young girls - Otoha, a headstrong country girl; Karen, a technical genius; and the highly-disciplined and strong-willed Eika - are being trained to pilot Sonic Divers, weapons being developed lest humanity be caught off-guard once again.
Earth is under attack by other-dimensional threats known as Nova, and only the Pandora – girls with special implants that grant them enhanced physical abilities – can battle against them to protect the planet. The military academy Genetics helps train the Pandora, who must choose a younger boy known as a Limiter to assist them in combat. Bridgette L Sattelizer, known to her peers as 'Untouchable', is at the top of her class and lets no one near her – that is, until new student Kazuya Aoi falls into her breasts one day...
The above is a preliminary synopsis that will be updated once more episodes of the anime have been released.
