The Manga Begins with Demon Slayer

Ryoma traveled to the world of demon slayers, but unexpectedly he was still hundreds of years away from the beginning of the plot. I never expected that my best friend would be Enichi Tsukuni! The key point is that this is actually the world of Demon Slayer: Kimetsu no Yaiba. Ordinary people may not be able to survive, and they may be killed by demons at some point... Several years later, looking at Mukai trembling at his feet, Jiguo Ryoma said that he just wanted to live. This novel and its characters are purely fictitious.
