Chrome Shelled Regios unfolds in a post-apocalyptic world overrun by mutated beasts known as Limbeekoon, or Filth Monsters, where humanity survives inside massive mobile cities called Regios. To protect themselves, people train to wield special weapons called Dite, channeling the power of Kei in battle. In the Academy City of Zuellni, Layfon Alseif is trying to begin again and leave his past behind, but the life he wants is far from simple. Karian Loss, the manipulative Student Council President, takes an interest in him, and Nina Antalk, a Military Arts student who serves as Captain of the 17th Military Arts Platoon, immediately recognizes Layfon’s exceptional abilities and believes he belongs with her group. As Layfon settles into Zuellni, the secrets tied to his history refuse to stay buried. His unknown powers and the weight of the past he is trying to escape make him a figure of both promise and danger, pulling him into the politics, combat, and rivalries of the city. With humanity’s survival always hanging in the balance, Layfon’s choices may determine more than his own future.
