Aldnoah.Zero, Kuromukuro Recommendations
War betweens Aliens and Humans.
The atmosphere is similar--- no one knows when an (mecha) alien will come down to attack the earth.
Great mecha fights, and there's some kind of Romance between the male MC and female MC
- Mecha anime with great graphics
- An interesting story and full of struggle
- A character who never gave up
- Boths shows have mecha.
- In both there is some kind of extraterrestrial entities that are attacking earth with these giant robots.
- The male protagonist meets the female protagonist in a chaotic situation, and they stay together for some reason.
Both series involve an "alien" invasion on Earth and humanity is forced to fight back with giant mechs. The invaders are more advanced in terms of technology, they also uses giant mechs as their primary invasion force but each one of them is uniquely different from one another due to the abilities/ powers they process.
