Space Alliance : It's only the Beginning

A war in deep space between the Space Alliance and The Fallers spreads throughout the galaxy which forced new discoveries on other planets. Arco a Space Alliance soldier was in charge of finding new recruits and began searching on Earth and decided on selecting 4 male humans to be an elite squad that could help them win the war. However, due to them being older than expected Arco was forced to kidnap them and convince them to join the Space Alliance and undergo a transformation that will age regress them into newborns and erase their memories in order to have a clear mind and be properly trained for the war since birth. Thanks to this the 4 boys were being well trained and due to them believing they are brother they were able to work well together as an elite squad. With war being unpredictable the 4 boys were given an injection by age 8 that would prevent them from aging and allow them to stay how they are.
