Demon Slayer: Starting Out as a Thug, but Around the Corner He Meets Mu Kai

(The protagonist is quite afraid of death... The protagonist doesn't eat people... If you don't like it, don't enter... You should think of this as Demon Slayer Gaiden... It's still some distance from the main plot) This is a story about a man who has just traveled to the world of demon slayers, and around the corner, he encounters Muzan and turns into a ghost. Then he wandered back and forth in this world, attracted a group of ghosts who followed him, and formed his own organization.
