I, Muzan the Demon King, Am Handed Over to the State by My Sister!

My name is Su Rou. You probably won't believe me, but my older brother is an evil spirit!

He can not only turn into a woman, but also into a child!

He's terrifyingly powerful, and he has a group of followers called the Twelve Kizuki!

What's more, he scares me every single day!

I've had enough. I've finally decided to report him to the authorities!

My name is Shu Mucheng. I'm the youngest director in the history of the Ghost Tamer Headquarters' Execution Division in Xuanlong Nation.

I'm also the only execution officer who doesn't use a ghost familiar, but instead slays ghosts with breathing techniques.

It all began with the guidance of an old man named Tsugikuni Yoriichi. My teacher told me I must one day eliminate an evil spirit called Muzan.

Today, my chance has come.
