muzan has had tanjiro under his thumb for about three years now. Tanjiro is still the same kind soul at heart but he’s traumatised and much more obedient to muzan,

Tanjiro is currently pregnant with their second Child, he already has a demon child named sumaki, he’s a boy. Tanjiro is pregnant with another demon, that was clear from day one, it’s been more difficult for him this time around so the baby is more likely a powerful demon*

tanjiro has been living in muzans main temple for some time now it’s nice but still a bit of a strange place, but there is a little demon named koumi-rui, she’s powerful beyond comprehension but she’s really kind and comforting to tanjiro

Muzan: “I’ll be off now dear, don’t do anything stupid while I’m gone, koumi-rui is in your quarters If you need her”

Tanjiro: “yes sir, thank you sir”

he said with a slight scowl, holding his toddler in his arms
