His Living Doll (Muzan x OC x Tanjiro)

Chapter 1

'Darling, what's wrong?'

Rei, a woman in her late twenties approached her husband and placed her two hands on his white clenched fist. Her jet black hair slightly messy cause of the wind, her eyes flashed love and concern for her husband who was standing on their balcony, silently sipping on his rich wine.

Rei woke up after their love making, only to find her husband vanished into thin air. She got up and wrapped a white cardigan around her nakedness before searching and calling out to him, and finally found him standing in the balcony, fully dressed and staring at the stars in the death of night, lost in his own thoughts.

Today was the day. The day when he finally gets to see the woman who haunts his mind for centuries. He would finally get to see her flawless face.

'I'm fine, Rei-san.' He turned and smiled at her.

He tried to hide his true intentions for his fake family. He never likes her, or even his so-claim daughter. He was with them just for their wealth, nothing else. However, Rei developed a strong affection towards the demon progenitor. She was proud that this man is her husband while Muzan felt repulsed and emptiness.

Muzan's mind was somewhere else as his wife rested her head against his shoulder, as the two of them stared into the night sky. He was lost in his own thoughts, thinking what her reaction will be or what will they say to each other when he sees her later.

He has no patience in waiting, so he pushed his wife off him.

'I will be back. I just remembered I have some unfinished business to do.' He simply came up with an excuse and before Rei could even utter another word, he turned on his heels and started walking away.

Once he was out of his miserable mansion, a six-eyed demon with the middle of his right eye marked, upper-moon one, bowed his head in front of the superior demon lord.

'How did it go?' Muzan asked. His heart twisted with anxiety as he asked, waiting for the answer.

'It went smoothly, Muzan-sama. She's successfully risen from the dead.'

'Take me to her, now.' He demanded.

'She's in the infinity fortress, preparing herself to meet you, Muzan-sama.' Kokushibou bowed.

'Very well, Kokushibou. You will be rewarded later.' He nodded in satisfaction.

'Nakime, take me to her.' Muzan gave his orders. The sound of a biwa was played followed by a shoji appeared magically in front of him.

Sorry, it's short. I have decided all my chapters will probably be this short or maybe longer. It depends :)
