Aquarion EVOL

The "Abductors", invaders from Altair, come to the planet of Vega with only one purpose: to harvest humans. Neo-DEAVA, a military academy based near the city of Neo-Kowloon, exists to train men and women to use technologically-advanced fighter planes known as "Vectors" in order to fight back against the Abductors, but members of opposite genders are forbidden from merging because of certain "Guize stones" that block such so-called "unholy unions". The story follows Amata's and Mikono's enrollment into Neo-DEAVA, their fight against the Abductors, and the discovery of their link with their counterparts from 12,000 years ago.

Based on the anime that aired from January to June 2012.
