Our Last Crusade or the Rise of a New World, The Last Battlefield Between You and I, or Perhaps the Beginning of the World’s Holy War, Kimisen, キミと僕の最後の戦場、あるいは世界が始まる聖戦
A power known as Astral force saturates all through the world, used by astral mages. Dreading its ruinous force, the “Realm” mistreats the individuals who show their capacities. The tortured mages then established the Nebulis Sovereignty to escape from their oppressors. From that point forward, the two countries have been in harsh clash, the war actually pressing onward for over a century.
