One scorching summer, the peaceful Earth transformed into a battlefield as the skies opened and sunlight poured in. Humanity, too weak to handle the new alien threat, saw its systems crumble, revealing the dark nature lurking within. To end the terror and control both aliens and humans, a new organization, X-Alien, launched a rocket to a hidden part of space beyond the moon.

They began experimenting on randomly selected children, injecting them with new superpowers to turn them into monstrous warriors for the space war. However, most of the children couldn't withstand the experiments, leading to countless failures. Amid this chaos, the first success story, 'Ellen,' emerged.

Unlike the others, Ellen retained her sense of self during the experiments and devised a plan to escape the lab. During her escape attempt, she couldn't leave behind the young test subject who had helped her, so she ran back through the long corridors.

Facing off against robots and researchers, Ellen fought with all her might, praying for a tomorrow where she could choose her own path in the war and where hope could return to the world. Help Ellen escape!
