A comic about the unfinished business of the past

Humanity has won the war against an alien civilization. Captain Noguera forms part of the troops stationed on the aliens' planet, transformed now into a colony of Earth. When a soldier named Castro joins Noguera's brigade, the captain recognizes him immediately: Castro was the sadistic ringleader of the gang that bullied him in high school. Now, Noguera finally has the chance to get his revenge. The story, which began in a high school on planet Earth 20 years ago, finds its resolution in a world dozens of light years away from our Solar System.
