In this au everyone is classified at 18 if their a little, caregiver, or neutral. What happens when you're a classified little and Muzan is your caregiver? How will his companions react?
It was too late as Y/n slammed the door and ran away from Mitsuris estate.
(Flashback)
A low ranked demon slayer had a evil plan to get closer to Mitsuri and get you out of the picture. She was gonna pretend to be a little and get close to Mitsuri. The plan was so perfect in her head and it almost worked.
Mitsuri was pushing you on the swing set Sanaemi built you in her huge backyard when the slayer fake cried and started putting her arms out to Misturi. The two of them were so confused since they've NEVER seen this girl before. Mitsuri feeling bad picked her up and started rubbing her back.
"M-mommy"
Mitsuris eyes widened in suprise. She didn't feel a spark but still wanted to help her. As you were following behind them the slayer evily smirked at you. 'This is a bad lady!' you thought and planned to tell Mitsuri when it was just the two of you. Unfortunately for you your mama spent the whole day with that woman. Of course she payed attention to you too but the majority of her attention was on the woman.
Mitsuri set up a mattress next to your crib and gave you both kisses goodnight and left to also rest for the night.
The lady walked over to your crib and started harassing you.
"Your mommy doesn't love you. She's gonna get rid of you just like everyone else will"
This caused you to start crying softly and put your blanket over your head to hide yourself from the evil woman. Next day rolls around and it goes hoe it usually does except she doesn't breastfeed you and just gives you a bottle. When you guys go for a walk she pushes you into the lake and claims it as an accident. In town she trips you and then says she didn't do it.
Mitsuri was starting to get more and more suspicious but she felt like if she was doing all this stuff to you would have said something. So she didn't do anything and continued on with the day.
When they all got home for dinner, Mitsuri accidentally gave her your favorite cup. She saw how upset this made Y/n so she slowly drank from the sippy cup smirking at you. This was the final straw and you pushed her over making her cry out(faking it ofc)
"Dear are you alright" Mitsuti comforted her and then looked at you in disappointment.
"Y/n why would you do that? Apologize now!"
"But-"
"Now Y/n!"
"I HATE YOU I LEAVING"
"Y/N WAIT-"
(Present time)
"Now Y/n I'm gonna need you to explain what happened again for me slowly okay"
It was hard for Shinobu to understand what she was saying becasue she was balling and stuttering a lot but the parts she did understand made her furious.
You explained the situation again and this time she understood everything. A huge tick mark appeared on her forhead and when i say she was pissed she was PISSED. Of course Shinobu didn't show it and only smiled at Y/n but even she could tell she was mad.
"Let's get you in bed and tomorrow we can talk to Kanroji"
Y/n nodded and let Shinobu tuck her in bed. Shinobu went to her office and told Obanai and Rengoku everything. Next morning rolls around and Obanai and Rengoku enter the estate and see Y/n crying into Shinobu.
Obanai was so mad. How DARE someone manipulate his crush AND hurt her little. Rengoku was more calm but still visibly upset about the situation. The three hashira hated seeing you cry like this. Shinobu even tried singing to you which seemed to work a little but you were still crying.
Shinobu looked up and saw her two friends.
"Is Kanroji on her way?"
The both nodded and waited outside for them. When Obanai saw who was holding her hand he rushed forward and kicked the slayer in the stomach. Obanai knew exactly who she was. Her name was Yukino. He overheard her talking about how much she hates littles and how she wanted to be Mitsuris tsuguko. Mitsuri was about to comfort her but Obanai stopped her.
"Don't fall for her lies Kanroji. She's only pretending to be a little to get closer to you. Yukino hates littles and probably wanted Y/n out of the picture so she would have you all to herself"
"Yukino is this true?!" Mitsuri yelled.
She got up and dusted herself off.
"Yeah it is mrs Kanroji" Yukino said in a fake apologetic tone.
Mitsuri rushed forward and lifted her up tightly grabbing her neck.
"So all the bad things that happened to Y/n yesterday was becasue of you" Mitsuri said with a death glare in her eyes. Yukino was starting to panick. Kanroji threw her into a tree and watched as she quickly got up and ran away.
"I can't believe I didn't see it my poor baby I have to see her" Mitsuri cried and ran into the estate looking for you. After searching a fee more rooms she found you with tear stains on your gave sitting on Shinobus laugh. Instead of running to her you hid into Shinobu bot wanting to see Mitsuri right now. This hurt kanroji worse than any demon ever could. She sat on the other side of the bed not wanting to upset you.
"Mochi I'm so sorry. I didn't know all those awful things were happening to you. If I would've known I would have beat her up sooner"
"You beat her up"
"I sure did" Mitsuri said and flexed her arm. This caused you to laugh and run in your mamas arms.
"Next time please tell mama if someone is being mean to you"
"I will"
