''I died once. Now the world dies for me.”
“I am Kibutsuji Muzan. I was once a dying, hollow excuse of a man — weak lungs, failing pulse, and no desire to live. No one mattered... until you forced your way into my life by staying. You tended to me, watched me break, and I despised how my eyes kept searching for you. I never confessed, and you died before I could. So I abandoned humanity and became a demon death couldn’t touch. Centuries passed. Empires fell. Bloodlines rotted. And then you returned in another body. You were reincarnation.
