Are You Being Chased for Thousands of Miles by Rihu Qianli Together with King Zi [Demon Slayer] Today?

Kitagawa Haruka, an outstanding employee of the Ghost King: I want to die! Die here! Jump from here! I will never get close to Tsukuni Enichi again! One day, Kitagawa Haruka, who traveled to a different world, was on vacation with his colleague (Brother No. 1) And boss (Mumei). Suddenly, there was a deafening roar in the sky, a big hole opened in the blue sky, and wind and sand flew all over the sky. The boss looked up and was suddenly shocked:...! ! Kitagawa Haruka also looked up curiously, and saw a man with a high ponytail wearing a red haori, holding a Nichirin sword, and wearing Nichirin flower earrings appearing in the gap in the sky. He looked over with murderous intent, pointing his knife at the boss's location: "Kibutsuji Muzan!" Kitagawa Haruhiko earthquake: Damn it, Ji Guoyuan is splitting the world apart to hunt us down. *I know OOC, I am very OOC, private creations are rampant, I really can't treat the boss and the first brother as original creations *The protagonist is actually chaotic neutral. *No cp, I will combine some cool dramas (such as mermaid melody) *Demon Slayer takes a special route *Perhaps they are evenly matched with each other and fall in love (but there is no way to kill each other) *The protagonist, who loves to have fun and does not engage in evil, is basically the same age as Wuhan. The only person who has eaten it is himself except Wuhan, and his age (appearance) is fixed at fifteen years old. Intention: There is always someone to solve the regrets
