S1 Muzan x mother reader (completed)

y/n's blood art

Y/N's blood art consists of mostly defense and only one offense skill

She has an always active skill that immediately controls demons around her to protect her.

Just like what happened to Doma.

When he surprised Y/n, her blood art immediately activates and controlled Nakime. The result was her making a door open under him.

A glow emits from the controlled demon's eyes. One of their eyes then will get a temporary mark of the text 'mother'.

The blood art will only disappear if Y/n does not feel to be in danger or if she or the demon dies.

No pillar can kill her, much less Tanjiro. He'll have to defeat countless demons until he gets her head.
