Seraphis, the former Templar Commander, died in a battle and woke up to find that he had become a skeleton without any skin. In order to keep the fire of his soul alive, he must find a job that pays social security (life essence insurance).
He confidently went to the "Wall of Sighs Cemetery" to interview as a night watchman, but the interviewer pointed at his withered ribs and laughed at him: "Brother, your body can't scare even a tomb robber. Go back and practice your chest muscles before you come back!"
Seraphis, who was deeply hit, embarked on the road to job hunting. He successively interviewed the "Personal Bodyguard of the Blood Count" (who was dismissed because he had no blood to spare), the "Sailor of the Netherworld Dockyard" (who was blown away by the sea breeze because he was too light), and the "Apprentice of the Crypt Butcher" (because he couldn't hold a sledgehammer).
After 108 failures, Seraphis finally turned black (crossed out) and awakened. If you can't compete with muscles, then compete with IQ! Instead of pretending to be human, he decided to take advantage of the skeleton's advantages - no need to breathe, no pain, and removable joints. He accidentally took over a "haunted B&B" that was on the verge of bankruptcy and transformed it into a "shared office space" in the world of the undead.
When the muscular men in major cemeteries retired one after another due to osteoporosis, Seraphis became the most popular "hardcore" CEO in the undead world by virtue of his bones that would never wear out.
