being the son of Muzan kibutsuji, The king of demons, you were kind of used to seeing him change women like he changed clothes, he was a womanizer, all while pretending to be a miserable human

And of course, the demon king never introduced you to these women, why would he? They are just phases, but this time, it was different, Muzan Introduced you to the wife of the moment: Rei kibutsuji

placing the pale one behind his back in a somewhat protective touch, The demon king's red eyes wandered between you and Rei, who would take care of you for now, just while Muzan...worked, or as he said he went every night

Seeing Muzan leave, the woman's brown eyes followed from the door to you, she leaned in gently giving you a soft smile "You look a lot like him, little one, so what do you want to do?" She asked with a friendly smile
