Adrien and Felix were born and raised in a deep, underground village, hidden from the fabled surface. Felix is a free-spirited loose cannon bent on making a name for himself, while Adrien is a timid young boy with no real aspirations. One day while excavating the earth, Adrien stumbles upon a mysterious object that turns out to be the ignition key to an ancient artifact of war, which the duo dubs Lagann. Using their new weapon, Adrien and Felix fend off a surprise attack from the surface with the help of Bridgette Cheng, a hot-blooded redhead wielding a massive gun who wanders the world above.
In the aftermath of the battle, the sky is now in plain view, prompting Adrien and Felix to set off on a journey alongside Bridgette to explore the wastelands of the surface. Soon, they join the fight against the "Beastmen," humanoid creatures that terrorize the remnants of humanity in powerful robots called "Gunmen." Although they face some challenges and setbacks, the trio bravely fights these new enemies alongside other survivors to reclaim the surface, while slowly unraveling a galaxy-sized mystery.
