Demon Slayer: A Hired Fighter from the Start, Then I Run Into Muzan

(The protagonist is terribly afraid of dying... He doesn’t eat people... If that’s not your thing, don’t read... Think of this as a Demon Slayer side story... The main plot is still a long way off.) This is the story of someone who has just transmigrated into the Demon Slayer world and turns into a demon after running into Muzan around the corner. He then wanders around this world, attracting a group of demons who follow him and forming his own organization.
