S1 Muzan x mother reader (completed)

24

The black haired demoness hopped from side to side, avoiding Muichiro's blade.

"I can't believe I dared to have a flashback when this kid's desperately trying to kill me" she sulked. Feeling sorry for him.

Now looking at his face, she felt giddy.
"He's so adorable!His stare is like the Tsugikuni twins!" She comments as she kept staring at his dull eyes.

But then...she halts and stands there in thought.
"Wait...he seems familiar to Koku—

ACK!!!

————————

Muzan pauses. His face darkened in anger while veins popped as he fumed.
"...mother..."

His eyebrows furrowed. His nails elongated. His aura darkened.
"...mother's..."

He turned to the scent's direction.
"...bleeding!!"

After that, in a split second. He disappeared and sprints off.

——————————

Y/n looks down to see Muichiro's sword stabbing her abdomen. Her blood pours out as he pulled his sword back hastily. Sighing, she looked up to him. "You know...you really should go now" she says. Her blood going back into her body and her stab wound sealing up right after the blood got in.

"Tsk! Why would I go now?! I already stabbed you!" He fumed. His grip on his sword tightened, stancing.

She went to touch the place he had stabbed her. The previous feeling she had felt was still there. Her arms was staring to get sensitive due to the new feeling. Looking up to him again, she tried persuading him again.

"Look, kid. You all are gonna die. They felt the attack, so they'll send it back" she stated. Her mind pertaining to the demons she had the command on. She still didn't deactivate it even though she had a link with Muzan. "Oh yeah... I still didn't deactivate it" she thought.

Yeah sure, at times she was timid like earlier with Obanai. But that was because Nezuko was there, if she got killed, the near demons will have an extra berserk. And also, Obanai doesn't easily listen to demons. Even if she said she won't kill anyone on their group, he's not gonna believe her. And, oh yeah. The sun was up, she's a demoness who needs a lot of space.

"What do you mean—

Rumble!!!

"What's that?!" Muichiro asked in surprise. Probably sensing a lot of incoming demons.

"I can control these demons and make them behave if you and your demon slayers go. There is but one demon that I can't control. If he catches you...then you're good as dead" she informed him blatantly.

Muichiro knows who the one demon is. But that didn't mean he's going to back down easily.

He grits his teeth and glared at her. Stancing, he hissed. "No! I won't back do—

"Geez, you really don't take orders from anybody, hm?" She whispers beside his ear. The mist pillar's eyes widened in surprise. "How'd she got behind me so fast?! I didn't even see her!!" He thought as he quickly turned to her. But before he even turned to her fully, she had hit the back of his neck, rendering him unconscious.

He falls limp and falls into her arms before hitting the ground. The surrounding demon slayers glared and pointed their nichiirin swords at her. The rumbling had stopped as she commanded the demons to stay and sit. Dogs.

But of course. She knew Muzan will immediately know her location. She was stabbed after all. He blood's scent is really easy to pick up as it's scent differentiates from other normal demon blood.

Turning to the demon slayers, she sighs. Some had overcomed her naked self. But still had a slight blush on her faces. Carrying the small hashira, bridal style, she walked over to them. They flinched back in fear but still stood strong.

"Hey, don't be scared. If it was another demon, he could've killed you right now" she states at them. Her eyes scanning their poor postures. "Ubuyashiki. Who the heck are training your kids?" Glancing to the side, she felt Muzan nearing.

"Here. Listen, and listen carefully" she tells them as she crouched to their height. Muichiro still laying on her arms. They had doubts but forced to listen. If the hashira can't handle it, so can they...not. They nod hesitantly.

"Thank goodness. I thought your gonna be like the pillar over here. He's not even listening to me" she chuckled. Only to have an awkward air.

Coughing to get their attention again, she gave them the pillar. A demon slayer slowly carries the hashira and walked back.

"A powerful demon is going to come kill you all, ok? I want you to get your legs working and run as fast as you can... alright? You value your lives after all!" She smiled sweetly at them.

Though, it sent a chill up their spine, they nodded. Nodding to the others, they run immediately. Their steps could be heard getting farther and farther away. Turning again, she rubs her nape. "He's still gonna catch up to them. Isn't he?"

Closing her eyes and fluttering them open again. She sees Muzan's chest infront of her. Looking up to his face, she giggled when seeing his enraged expression.

"Mother..."he mumbled.

"Pfft. It's always funny to see that angry face of yours, my darling."she giggled yet again.

He frowned
"You let him stab you...why?" He asked. Not really wanting her to receive pain.

Y/n smiles at him and embraces him. Her chin rested on his broad shoulder. "Hush. Let's just go back" "I really wanted to spy on the hq..." she thought at the same time.

She knew that he'd chase the poor demon slayers in just seconds. So embracing him was the only choice. He's different when she's hugging him after all. Despite feeling bloodlust, it was all deteriorating away as he stayed in her arms. He calms down and step away.

Removing his coat, he drapes it over his mother's shoulders and kisses her forehead. Y/n closes her eyes as it was rare to have him being sweet and kind. Feeling his warm kiss go away, she fluttered her eyes open and smiled.

"Let's go mother" he spoke. His hand holding her shoulder gently.

"Hmm, lets" she nods.

In just a split second. They disappeared.
