Ep 1. Bust Through the Heavens with Your Drill!!

In the far-off future, humanity has been forced to live underground by creatures known as "Beasts". The young Simon is a humble driller living in one of these underground villages who dreams of one day breaking through to the surface. He idolizes the village leader, Kamina, who shares a similar belief and is known for his attempts to break through to the world above. One day, Simon discovers a small drill-shaped object while digging and, unbeknownst to him, he has found one of the ancient artifacts known as "Lagann," which Kamina recognizes as a legendary mech from the surface.

Kamina and Simon decide that it is time to finally take action and break through to the surface world using Lagann. Without the permission of the village elder, they take off in the newly discovered mech, determined to see the world above. While on the surface world, Kamina and Simon encounter the Beastmen, who pilot their own massive robots known as "Gunmen". Kamina and Simon are initially overmatched but, against all odds, they are able to best the Beastmen with the power of Lagann.

Upon defeating the Beastmen, Kamina and Simon find themselves being hailed as heroes, and the people of their underground village are inspired to take up arms and rebel against their oppressors. Kamina, believing that he is destined for greatness, declares that he will break through the heavens and create a new world.
