My Brother, Muzan [Demon Slayer]

My brother is Muzan, and my wife is Muzan. ...As the saying goes, if you haven't done anything wrong, you don't have to fear a knock at the door. Maybe Muzan had done too many bad things as a child, because the first thing he saw when he opened the door was a ghost. His little brother Yingxu ::) Muzan was so scared that he slammed the door shut. After a while, thinking his brother had left, the scumbag boss opened the door again. A certain female ghost king :D Muzan trembled in fear as his little brother pulled him into his arms. The incoming employee, Brother Tsugikuni: ...??? Look at how happily Muzan is smiling. ...This body was once as faint as a firefly. As heavy snow filled the sky, I dragged my cold, dying body up the ninety-nine stone steps, lighting the lanterns on either side. I purified my hands with snow, rang the bell, clapped, and prayed. The lofty god bestowed upon me an ever-burning lamp. I will lead you into the fading glow of lamplight and imprison you in an endless night. ...The younger brother is evil, with psychological distortion, verbal and physical abuse, and all kinds of torment. This story is about brotherly love. Please enjoy.
