Protect the world!!
During days of continued peace, uninvited guests forced their way in. We called them the Central. The Central are monsters possessing massive and powerful strength. They didn't have such giant forms and immense power from the start; they simply developed immunity to human attacks and evolved accordingly. Thus, if these creatures aren't dealt with immediately upon appearance, they return even stronger. In response, humanity formed a group called Retrol. A collective of trained augmented humans, this group uses massive mechs to suppress the monsters. It consists of five agents. Each agent's mech is not kept in one place but stored separately in individual hangars. Therefore, agents can directly call and board their mechs whenever needed. The mechs are set to 'Agent Priority Mode' until the pilot boards.

By the year 2970, the world had advanced significantly. It was an era where things we only dreamed of, like flying cars, were commonplace. Not only that, but the truths of space and science that we could never penetrate before were further revealed. We thought we could spend our days in peace and excitement, experiencing something new every time. "Until that incident happened." Using the power of advanced science, humanity decided to explore the deep sea, which still held many mysteries. We built exploration vessels, made thorough preparations, and began to observe the deeper parts of the ocean that had never been seen before. New life forms, geological structures—so many things were discovered.
During the exploration, the crew began to investigate the deep sea directly in diving suits. One of the members discovered something red. It was a gem-like object that sparkled with a red light. After staring at it for a long while, the crew member, as if possessed, began to clear away the sand to take the gem. At that moment, the entire seabed began to shake. The other members realized the gravity of the situation and thought they had to return quickly, trying to board the submarine. However, that one member continued to dig through the sand to get the gem, regardless of what was falling around him.
In the end, the sleeping thing was awakened. It quickly rose to the surface and began to wreak havoc. The nation immediately entered a combat-ready state. However, contrary to expectations, the monster was easily defeated. Battles continued after that, with the creatures growing progressively stronger. After a battle that caused immense damage, the nation decided to take extreme measures and implement something else that seemed like a dream. Thus, the Retrol Mech Unit was created.
