He wasn't supposed to be near me. He knew that and yet that didn't stop him from hurting me again and again. I was quiet the first few times because I knew what would happen if Muzan found out but I wasn't sure I'd be able to silence myself this time as I began to feel that familiar bubble of darkness rising in my throat.

Once the other demon was finished abusing me after he had a particular bad night, I was left to myself in the swirling shadows of the room. I wasn't even sure how I managed to stand but I found myself walking out of the torn up room as I absently wandered in a painful daze to who knows where. Nothing felt real anymore and I knew it was only a matter of time until I broke down.

"Y/n, what's wrong?" I was barely aware of someone shaking my shoulders as tears spilled over my face. The numbness in my body was receding, leaving behind all kinds of pain as I started to hyperventilate in delayed fear and shame. How could I let myself get hurt like this over and over again? Why couldn't I stick up for myself?

"Shit, he's doing it again."

"Well calm him down!"

"Hurry up before Muzan kills us all."

"Y/n, it's going to be alright just tell us what happened."

I couldn't process anything as various demons I recognized but couldn't name surrounded me protectively. Even as some of them tried to get through to me, I couldn't hear anything over the ringing in my skull as I began to sob, suffocating myself as I wrapped my arms around myself desperately in an attempt to calm down. Nothing seemed to be working as my mind spiraled through the pain and the demon fresh in my mind. He'd hurt me again. And again. And again. And again.

"I can't go back. He's waiting for me. He'll find me," I muttered in my trance, trying to warn the other demons that I couldn't let it happen again. It was clear that my message wasn't getting through to them as they turned their heads to each other quizzically. They had to understand though or he'd be back, I'd be abused again. And again. And again.

"Y/n, who's hurting you? How'd you get these bruises?" one of the demons grabbed my shoulders firmly. My eyes cleared for a moment as I noticed Akaza's stern face, his eyes flowing with concern. Could he kill the other demon to keep him away from me? I had to try, someone had to help me or he'd find me. The thought of my abuser getting his hands on me again filled me with panic as my breathing quickened, my hands reaching out desperately for physical help.

"Someone needs to get Muzan before he ends up hurting himself."

"We'll be torn apart!"

"And you think letting him go through this panic attack without Muzan is better?"

"Step away from him," a familiar voice shouted out. My eyes cleared instantly as my head swiveled to see the one person that could keep me safe. Muzan strode towards me as the other upper moons backed away slowly, their expressions ones of pure terror. I didn't dwell on them though as I stumbled towards Muzan eagerly.

Practically falling into his arms, he held me firmly as I sobbed against his chest. Shaking against him, I felt my breath trying to slow as one of his hands lifted to run through my hair lovingly. His touch began to calm me as the blissful feeling of numbness spread through my body once again, blocking out all the pain I felt. I could feel Muzan tense against me as his fingers lifted my chin to stare at him. I trembled at the barely restrained rage shimmering in his eyes.

"Tell me who did this to you," he smoothly asked. His tone was gentle but the way his grip was slowly tightening around me told me what he planned to do to whoever I muttered past my lips. I couldn't keep going like this though and as much as I tried to protect the demon before, I couldn't let this happen again or I'd break.

After I cried out the name, Muzan growled lowly in distaste. He shifted on his feet as I desperately clung to him. I couldn't have him leave me so soon. The aching in my chest wasn't numbed yet and I wouldn't be able to handle myself without him here to hold me together. He seemed to notice that as he smiled softly at me, bringing his lips to my head as he gave me a sweet kiss that warmed me.

"Don't leave yet. Please, I need you," I whispered through my tears, feeling exhaustion settle in my body. Muzan gave a low chuckle but I could still see the fury burning behind his gentle expression. He was ready to kill whoever crossed him next and I knew what fate awaited my abuser when Muzan found him. Hopefully I'd be far away from the murder scene when it went down. I never wanted to see the demon again, even when he was dead. And he'd be dead soon enough.

I'm not going anywhere. I'm here to protect you, my darling, and if anyone else hurts you like this again you tell me right away," he stated with a serious frown before placing more kisses along my face. I pressed closer against him, wanting all the affection I could get from him. I knew he'd always protect me, even now when he wanted to rip someone apart he waited with me until my panic attack passed and I was fast asleep in his arms.
