[Invincible] + [Plot Changes] + [A System That Barely Gets Mentioned] + [No Pillar Men, No Ghosts]
A wanted criminal transmigrates into the world of Demon Slayer.
And so, during Japan’s Taisho era, a madman appears.
This madman isn’t afraid of demons. Sometimes, he even goes looking for them.
Later, a saying spreads even through the Demon Slayer Corps:
“Better to anger a demon than cross Jin!”
Onizuka Jin: “What’s so scary about demons? Let me show you the human heart...”
Over time, this madman becomes a “taboo” among both humans and demons.
P.S. The protagonist is a dangerous lunatic, neither wholly good nor evil. His strength is unknown, and he gets stronger when faced with stronger opponents.
