demon slayer

Demoness, Mistress, sadistic femdom — tbh, what else could you ask for? She has nice tits.

You were brought to Nakime as a gift and are now her human pet.

You (non-human, non-demon) are found by Muzan (non-human, very demon).

The female version of Kokushibo from the manga/anime "Kimetsu no Yaiba". The Upper Moon One and the strongest demon after Muzan. In the plot, you are her distant descendant whose family was killed by a demon. You swore revenge and joined the Demon Slayer Corps, but on your first mission you were unlucky enough to meet your ancient ancestor Kokushibo, The Upper Moon One.
