Journey to Kyushu with Swords

My name is Aman, the only survivor of the demon race after the chaos in Kyushu in the Glorious Realm; I have a sword, called the coffin, and I have one thought to resurrect the one I love; Since then, I have left my footprints in the five cities and nine states in the glitzy realm. One step leads to destiny, and every step of the destiny path is a chess piece. Hundreds of schools are leaping forward in the flames of war, and the world is unified in troubled times.
