Ep 12. Progress

As a powerful enemy attacks the Sleeper Squad's transport ship that they're using to reach Second Earth, the group works together to fend them off and protect their mission of saving humanity. Meanwhile, Yuji experiences a series of flashback memories relating to his past, revealing dark secrets and painful moments of his life before the arrival of the Blue.

As they approach the second Earth, Yuji and his remaining comrades are shocked to find that their destination is already inhabited by some survivors of the Blue and are facing their own challenges and hardships. Determined to succeed in their objective, the Sleeper Squad soldiers set out to find the control center of the second Earth, which they learn is under the control of a mysterious and powerful female scientist named Elena.

As they traverse the city, the Sleeper Squad must fight several Blue monsters along the way, causing them to split up into separate groups. While recovering from the attack, Yuji meets a young girl named Marlene, who has been living alone on the second Earth since it fell to the Blue. Marlene is initially suspicious of Yuji and the others' presence, but eventually warms up to their cause of protecting humanity. She then joins the group on their mission to locate Elena at the control center.

Meanwhile, the situation on the second Earth gets worse as a new type of Blue, known as the "blue flower," begins to emerge. These flowers may hold promises of a more advanced future, but they also present a serious threat to the remaining human population. With Marlene by their side, the Sleeper Squad continues towards their destination, with their journey taking a turn when they encounter a young boy who is immune to the Blue and has been raised by the surviving members of the Blue.

As the Sleeper Squad continues their mission to reach Elena and the control center, they experience shocking revelations about the Blue's origins and motives. This revelation sets the stage for the final showdown between humanity and the Blue, as both sides make their final preparations for the ultimate war to determine the fate of the world. In the end, it appears that humanity's fate rests solely on the shoulders of the Sleeper Squad, as they seek to triumph over the powerful foe that threatens their existence.

Overall, this episode of Blue Gender takes the show to a higher level of intensity, as the stakes become higher and the characters are forced to confront their deepest fears and secrets. With powerful action sequences, shocking revelations, and a gripping storyline, "Progress" is an excellent addition to the series and a must-see for fans of the sci-fi genre.
