[Invincible] + [Plot changes] + [One-shot system] + [No pillars, no ghosts]
A wanted criminal travels to the world of Demon Slayer: Kimetsu no Yaiba.
So, during the Taisho period in Sakura Country, a madman appeared.
Not only is this madman not afraid of ghosts, he sometimes actively seeks them out.
Later, even among the Demon Slayer Squad, there was a saying:
It's better to provoke ghosts than meet Jin!
Onitsuka Jin: What's so scary about ghosts? I'll take you to see people's hearts...
Over time, this madman became a "taboo" among people and ghosts.
Ps: The protagonist is crazy about criticism, he is both good and evil, his strength is ominous, and he becomes stronger when he encounters the strong.
