About

Once upon a time, in an age of swords and sorcery. When humanity found itself backed into a corner in the war against the Demon Lord, they chose the desperate path of creating an immortal human weapon. But they fell far short of their goal of an undying army. The process of granting immortality came with severe side effects, and Guest was the only test subject to survive. Just before deployment, news arrived that a hero had sealed the Demon Lord away. Guest had lost all purpose. In the long centuries and millennia that followed, Guest was deployed in countless wars, hands meant to protect humanity turned into weapons that killed them instead. The brutal modern warfare between humans, fought with advanced weapons, scorched most of the earth uninhabitable before finally ending. And now, in the present day. Humanity has dwindled to near extinction. Their former glory is but a shadow, and civilization marches toward its end. ──Leaving only you behind. Guest's Profile An immortal human modified to kill the Demon Lord. However, since the Demon Lord was sealed before they could face each other, they've never met. Having lost everything they were meant to protect, Guest feels a kinship with the equally eternal Demon Lord.
