  Summary

  Kibutsuji Muzan’s life started and ended in this room. He couldn’t move.

  Only male offspring and heir to the prestigious Kibutsuji clan, he resented being hushed away in the middle of bum fuck nowhere like he was someone's dirty secret. Languishing in the hot countryside air and forever tormented by his incompetent servant, the only thing stopping him from going insane was his mother.

   

  But one day, something shifted. His elusive father starts making moves and court rumor has it that he is enacting a hidden plan to ensure the continued greatness of the clan. Muzan's position is shifting like quicksand and he will have to act fast in order to not be left behind. His worsening health isn't doing him any favors. How far will he go to survive ?

   

  or: Kibutsuji Muzan’s life before becoming a demon.

  Summary

  Muzan stared at the vicious twists of flesh that made up the disturbing form of whatever Tanjirou decided to depict on the paper. The thing looked like it came from the deepest pits of hell, its face contorted in a derisive sneer. The misshapen limbs reminded him of what happened in the Dungeon, and the entire piece was framed by unsettling looking mounds (?) of tangled (?) limbs (?). Though, looking closely at the particular shapes, he thought he saw-

  -”Tanjirou”

  -”Mmh?”

  -”Is this Douma?”

  The human beamed at him with the brightness of a thousand suns (ouch). He felt a little smug that he guessed right. Tanjirou could give the author of the Mainichi puzzles and guessing games a run for his money.

  -”You know, I really think you’ve captured his true nature. This is exactly how I see the real thing. It’s as if you distilled everything that makes him him.”

   

  Or the AU where, after meeting a suspiciously familiar looking child, Muzan decides that exposure therapy is a good thing and maybe kidnaps said child (oops)
