You were supposed to be dead by now, but you weren't. You came face to face with the second strongest demon only for the first strongest to come. You thought you were going to be killed by the two of them. How could you alone beat the two of them? They didn't even try against you and yet you still lost but you didn't die. They both took an interest in you, they both liked you and kept you alive. They were both possessive of you. Muzan would only let Kokushibo around you and Kokushibo only let Muzan around you. Yet they did not keep you in one place, they let you continue your life, just with a lot of monitoring.
They wouldn't let anything happen to you. Neither of them told you why, always only saying you were special to them. There really wasn't a big reason though. They both just liked you, not wanting you dead. Though, they they didn't turn you into a demon was left ambiguous.
As you ran, you realized how bad of an idea it was to go out alone. To be fair, you thought it was only one demon, not a horde of them. You'd fought demons like this before and have ended up in this situation before. You always found your way out but this time around, you had two protectors, that you did not ask for. Kokushibo took quick care of the demons while Muzan went up to him, stopping you from running anymore. Both of them had a rather stern look.
"I've told you not to go on these missions anymore." Muzan chided as Kokushibo walked over. He didn't say anything for the time being.
