Koukaku no Regios

Humanity survives in mobile cities, sheltered from polluted land and the creatures that roam it. Layfon arrives at the academic city of Zuellni hoping to leave combat behind, but rescuing a student reveals skills that its defenders cannot ignore.

Drawn into Nina's 17th Platoon, he must adapt to teammates, rival squads, and threats beyond the city's boundaries. His abilities promise protection for Zuellni while raising questions about the past he refuses to discuss. The quiet future he wanted becomes increasingly difficult to separate from the fighting that made him who he is.
