Zero's Familiar Night Sword God

An unknown swordsman crawled out from the center of the battlefield where he once had an enemy of 70,000 people. With the sword in his hand, he was still looking for traces of the enemy, but there seemed to be no more powerless monsters here, and the powerful companions around him no longer existed.
