If Tanjiro Kamado knew the truth of our world, he would realize that demons no longer hide in the shadows of the night. They walk among us in daylight. They wear human faces. They speak with calm voices while slowly taking our freedom, chaining the soul, and turning living hearts into quiet prisoners. In this age, the line between demon and human has almost disappeared. Some wear no fangs, yet they still devour everything that makes us free. Some never raise a blade, yet they leave deeper wounds than any blood demon ever could. And still, somewhere inside us, the same fire that once burned in Tanjiro refuses to die. Because even if the monsters have changed their faces… the fight remains the same.
