As a Maid, I Must Conquer Wujan

"I was so foolish, truly," a certain maid said sadly, stroking her slightly swollen belly. "I knew this would have serious consequences, but I never imagined it would turn out like this."

A certain Demon King: "Mu, I’m back."

A certain maid: "Welcome home, Lord Muzan."

Set in the world of Demon Slayer, this is the story of our protagonist and the Demon King Muzan, a story that simply must be told.
