Meet the Skeleton Soldier, a meager but fiercely loyal fighter who serves to protect its master, Lady Succubus. Its dream of a peaceful life with her is shattered when they're both brutally murdered by a group of warriors one day. But what would’ve been a pathetic end to an unremarkable soul sparks a new beginning: when the Skeleton Soldier opens its eyes again, it has traveled back 20 years in time! “I must warn Lady Succubus of all the things to come!” But with no special combat skills and a history of failure and defeat, how can it stop the horrible events from unfolding again? Follow the Skeleton Soldier as it faces the most challenging quest of all—rewriting the ending to its own story.
