Koukaku No Regios

This novel retells about a severe future that brings natural disasters and pollution. The environment is undermined by beasts that make people leave houses, nomadize and settle in portable locations named Regios. One such district is Zuellni that serves as an actual school where Layfon Alseif attended. Layfon wasn’t enthusiastic to refer to the 17th Military Arts Platoon, submit to an older student Nina Antalk and tolerate sudden adventures.
