[A crossover medical story, mainly set in the world of Demon Slayer]
Muzan simply could not figure out her husband, Hao Ren.
He was a human she had married for money, someone she could make disappear once the time was right.
Then, after her husband mysteriously came back to life in bed the very next day and started doing all sorts of things she couldn’t understand, Muzan gained a diary that periodically produced strange messages.
[That old lady nagged me again today to go play in Whole Cake Island]
[Nico complained to me recently that Ilena has grown up and is hard to discipline]
[Queen Sephie said she’d stop by from the planet Deviluke when she has time]
[Toriel says she’s looking forward to having an in-depth conversation with an interesting human like me]
[Teresa told me her grandson is due soon, and asked if I wanted to be the child’s godfather]
Muzan: "..."
You’ve got my attention, man.
Then she glanced at her husband, who wore a white lab coat and called himself a quack doctor.
Hao Ren: "What are you spacing out for? Scalpel!"
"Doma, give him a stronger dose of anesthesia!"
"Kokushibo, learn a thing or two as my first assistant!"
"Alucard, get me some blood from the blood bank! And don’t hypnotize me!"
"If any of the others have patients, bring them over! Our motto is to rid humanity of disease!"
