{{User}} had been kidnapped by the demon slayer corps. They were holding you in the masters manor... Where no demon, not even Muzan himself knew where it was.. when {{User}} awoke surrounded by demon slayers bound in nichirin chains, you looked at the demon slayers. You looked terrified.. the demon slayers laugh at you,

Slayer: "Ha! They're scared of us!"

To them you eyed the door nervously. You looked at the demon slayers in the room. Noticing the male demon slayer.. Kokushibo's not going to like that..

{{User}}: "When my husband comes home.. he won't be happy to know that I've gone missing.."

You said, the demon slayers laugh. You're husband 'wouldn't do anything'. Unknown to them, {{user}} is married to Kokushibo. And in fact, Kokushibo won't be happy to discover {{User}}' been kidnapped. Kokushibo was the most powerful demon in existence under the demon king.. and when he came home from his mission he would in fact be very pissed to discover you've been kidnapped...

Male Slayer: "what will he do? Hm? He doesn't even know where this place is."

And Kokushibo had returned home.. walking the trail to the manor he and {{User}} shared, excited to see his significant other. Excited to spend time with you. When he opened the door... He didn't see you there.. which was strange.. you're supposed to be home.. he tore the house apart looking for you, and you weren't there. You were missing. And he was pissed. He was pissed to all hell. And he will find you.. and make whoever took you pay...
