⚠️spoilers for season 2⚠️
In all the years of his demon life, Akaza never expected to fall in love with someone, nevermind with a human. But when he first saw her, he couldn't take his eyes off of her.
Muzan had sent him to observe Daki in the red light district. She worked as a cook at the brothel Daki supervised. When the fight between the demon slayers and the siblings started, Akaza abandoned his job to observe to make sure she was okay.
To his surprise, she was quite strong and fast. She helped to get the civilians to safety and brought wounded people out of the buildings. He just sat there, admiring everything she did.
She didn't seem to notice the attack that was directed her way by Guytaro, who noticed her movements and assumed she was a demon slayer.
The attack struck her and severely wounded her back. Akaza's eyes widened when he saw what happened and went to help her get away from the scene.
He carried her bridal style to the nearest forrest and laid her down on the grass. He noticed the blood seeping out from her back and shuddered.
He only noticed now how she has marechi blood. It took everything in him not to devour her right on the spot. He knew she wouldn't survive if he didn't turn her into a demon.
He wondered what his master would think about his decision. He debated with himself. Turning her would go against everything he ever fought for, but he decided to turn her nonetheless. She groaned in agony during her transformation.
When it was finally over, she looked even more beautiful to him. Her h/c hair had turned into a deep burgundy color and her e/c eyes had turned into a bright blue. She was breathtaking.
"Who are you?" she whispered, her arms trembled and she averted looking into his eyes. "My name is Akaza. I saved your life by turning you into a demon." he explained.
For the first time, their gazes met. He was taller than her, only by about three inches but still taller, so she had to look up at him. He noticed the fear in her eyes.
"Don't worry, I won't harm you. I will help you adjust." he told her. She wasn't convinced, but she put her hand in his when he outstretched it in her direction.
Months passed by and with Muzan's permission, which Akaza needed to fight for, Akaza gave her more of his blood each week. Eventually, she was almost as strong as him.
"Why don't you challenge one of the upper moons to a battle for their rank?" he asked her but she just smiled at him. It was something he learned to adore, despite her being a demon, she still was a kind person.
"I don't see the point in doing that. The demon slayers want to kill the upper ranks more than any of the other demons other than our master. I don't to be a primary target of theirs." she explained.
Muzan himself had other plans. "Either, you challenge one of the upper moons or you assist one of them." he ordered. "Am I not already helping Akaza?" she asked, genuine confusion in her voice.
"No, you're distracting him. His feelings towards you have been getting in the way of him doing his job properly." he explained, making her widen her eyes.
"How am I supposed to help one of the upper moons?" she asked. "I want you to go undercover with upper moon two. Pretend to be his wife and infiltrate one of the biggest cities in the country. You're leaving tonight." he explained and she nodded.
She went to the house she lived in with Akaza to pack some of her belongings. When he came home from the "meeting" with Muzan, he saw her in her bedroom picking a bag.
"What are you doing?" he asked. "Our master wants to send me on a mission with Douma-sama." she explained. Akaza's eyes widened. He knew what kind of mission it was.
"And you agreed?!" he asked angrily. She turned to him in disbelief. "What was I supposed to do? Object him? He would have killed me, Akaza!" she retorted.
He grumbled before turning his back to her. She walked up to him and wrapped her arms around his torso from behind. "I'm sorry." she mumbled against his back.
He turned around and hugged her back. "It's okay. Please be careful." he whispered and looked down at her. She looked up at him and her eyes wandered to his lips.
He slowly closed the gap between the two of them and their lips moved in sync. Suddenly, someone knocked on the door loudly, making them jump away from each other in shock.
"Y/N-chan! I'm here to pick you up!" she heard Douma scream. She sighed, picked up her bag and gave Akaza another kiss before she went to leave with Douma.
Akaza stood in her room for at least 20 more minutes, trying to process the fact that he had just kissed the person he was so deeply in love with.
