Chrome Shelled Regios (Light Novel)

In a post-apocalyptic world overrun with great beasts called Filth Monsters, a glimmering dome protrudes from the wasteland. This is Zuellni, a mobile city unique for having a consciousness in the form of ‘electronic fairies’. Moreover, Zuellni is an academy where the next generation of powerful Heavens-Blade wielders gather to pit their strength against each other in inter-platoon competitions. Nina Antalk, military student and leader of the 17th Platoon, is intent on recruiting only the best; thus, when mysterious Layfon Alseif transfers to the academy, she instantly recognizes his abilities and decides he’s the perfect candidate to join her group. However, with a secret past that won’t leave him alone, and unknown powers beyond the academy taking an interest in Zuellni, Layfon joining the team is only the start of all their troubles.
