Synopsis
In a desolate future ravaged by monstrous creatures, humanity clings to survival within massive, mobile cities called Regios. These cities are constantly on the move, evading the monstrous Filth Monsters that roam the wasteland.
The story follows Layfon Alseif, a young man seeking a fresh start in the academy city of Zuellni. He hopes to leave behind a mysterious past and live a normal life.
However, Layfon's exceptional abilities quickly draw the attention of powerful figures within Zuellni, including the shrewd Student Council President and the determined Captain of the 17th Military Arts Platoon. They see him as a valuable asset in the fight against the Filth Monsters.
Despite his desire for a quiet life, Layfon finds himself pulled into the conflict, grappling with his hidden potential and the secrets of his past, all while trying to navigate the complex social and political landscape of Zuellni.
