An anime series by OLM, aired from October to December 2021. A second season aired from October 2022 to March 2023.

In the near future, 99.9% of humanity was nearly wiped out by an unknown alien race known as "Dracters", which have drilled a hole through the planet and terra-forming Earth into a more suitable place for its species. This forces the surviving 1% of mankind to seek refuge in heavily-fortified shelters and having their memories of the invasion repressed, allowing the unknowing survivors to live in peace while the unified world government and its forces tries to fight back against the Dracters using armored mechs known as "Rogues", seemingly with no avail. Yamato Ichidaiji, a hot-blooded and psychopathic teenager who recently beginning to experience horrifying flashbacks of the Dracter's invasion and the resulting death of his family, was chosen to be one of the pilots for the newly-developed Megaton-Class Rogues, alongside other chosen teens: Teru Asami, a calm-headed, yet narcissistic teen who has prominent ties with the unified government; Ryugo Hijikata, a brawl-happy delinquent; Reiji Amemiya, a cat-loving pacifist; and Jun Kirishima, a feisty and talented girl. Vowing vengeance on the Dracters, Yamato, along with Teru and Ryugo, pilots a special three-component Megaton-Class Rogue known as "Musashi" as he and the other chosen pilots fought a secret war that will decide the fate of Earth and what remains of humanity, which became even more complicated as Yamato crosses paths with a runaway Dracter princess named Arshem Laia, who strives for her people to peacefully co-exist with mankind. The Rogues
In an effort to protect mankind and hopefully turn the tide of war against the Dracters to their favor, the united world government have built armored bipedal machines known as "Rogues" to protect the heavily-fortified shelters made to house the last of humanity. Designed to be mass-produced and deployed in large numbers, the Rogues, while less durable, are capable of taking enough punishment before breaking down. Nowadays, the regular Rogues are used as cannon-fodder for their more advanced successors. Sometime later, development on a series of next-generation Rogues aboard the Shelter Ixia was reportedly finished and was later dubbed "Megaton-Class Rogues". These Megaton-Class Rogues are made from a special type of metal called "Megatonium", which was said to be stronger than any known metal ever known to man, making these type of Rogues more powerful and durable. Musashi
The titular mecha of the series, named after Miyamoto Musashi, primarily piloted by Yamato Ichidaiji, though Terui and Ryugo occasionally operate the Rogue prior to getting the Sparkman and the Gaudia. Being the "jack-of-all-traits" amongst Megaton-Class Rogues, Musashi uses its twin swords to cleave through numerous enemies with relative ease, as well as firing a powerful beam from the Diffusion Cannon in its torso, obliterating anything unlucky enough to be caught in the blast. Unlike most Rogues, the Musashi has three separate components, the Upper Torso, the Arms and the Lower Torso, which must be assembled together on higher altitudes via the Sky Build (スカイビルド, Sukaibirudo) formation. Arthur
Inspired by the heroics of legendary King Arthur, this Megaton-Class Rogue excels in close-quarters combat using its sword, as well as possessing a centaur-like lower body, enabling greater mobility and agility amongst other Megaton-Class Rogues. Primarily piloted by Reiji Amemiya. Maximus
The range-focused fighter amongst the Megaton-Class Rogue, the Maximus utilizes the many missile pods in its body to fire an endless salvo of heat-seeking missiles to wipe out multiple targets at once. Inspired by the Pontifex maximus. Primarily piloted by Jun Kirishima, with Momoka Saotome serving as the co-pilot. Sparkman
Inspired by Thomas Edison, the Sparkman is able to make use of the electricity it constantly generates, either to augment the destructive potential of whatever weapon the Rogue is holding, or by harnessing its raw power to amplify its attacks through a variety of ways. Primarily piloted by Teru Asami. Gaudia
The physically strongest out of all the Megaton-Class Rogues. Inspired by the brave warriors of ancient Rome, it utilizes the raw strength to crush its oppositions through sheer might alone, as well as using its large body to shrug off any blunt hits. Primarily piloted by Ryugo Hijikata. Characters
