Demon Slayer One-Shots / 鬼滅の刃 ワンショット

A Beast's Demon (InoAoi)

This was requested by "Svftmxlti" and sorry for taking to long to get this out but guys updates will be slow for this week and the next 2 weeks because I have summer music school at 9 to 12. So enough of that and let's get started!

"Inosuke! I specifically told you not to bring her with you and now you go and pull this!?" Shinobu yelled at the beast breather who coward under her gaze. "I-I'm sorry I just wanted her to see what it was like battling these things. I didn't intend her to be turned into a demon" Inosuke said basically at a lost for words as he couldn't believe that Ali is now a demon. "I'm very disappointed in you, Inosuke. I really am. I want you to go to the room your staying at and stay there and think about what you have done" Shinobu said acting like a mother towards him.

Inosuke nodded and walked towards his room where he opened the door and shut it as he sat down on the floor. It was dark and Inosuke felt like his room was just plain black with no other objects. The mission he went on with Aoi still fresh in his mind.

Flashback....

"Now Inosuke, I have a special mission for you. I would like you to kill a specific demon that has the powers like Muzan to turn people into demons. And with your immunity to turning into a demon it would be fitting for you to go" Ubuyashiki said as he smiled at the beast breather who wore a smirk under his boar head. "The great Inosuke will exterminate that demon! HAHAHAHAHA!" Inosuke said as he leaned back as he laughed. The master just held his smile and stood to make sure Inosuke had left.

Inosuke was walking with his arms behind his head walking with pride. He then opened his eyes to see Aoi doing the laundry not paying attention to him. "HEY , SOAI!" Inosuke said scaring Aoi making her drop the towel in her hands. She closed her eyes and heaved out a long sigh as she crossed her eyes making her facial expression into frustration. "Inosuke! How many times have I told you to not scream! Use your inside voice or I will have Shinobu punish you!" Aoi said and the mention of Shinobu's punishment gave him fear like chills up his spine. "S-Sorry..." Inosuke said toning down a small bit. "Anyway. What do you want?" Aoi said picking up the towel and patted the dust off. "Oh. I'm going on a mission! Lord Inosuke orders you to come with me! So you can see how better I am than everyone else!" Inosuke said puffing out his chest in pride. Aoi tried not to stare at his strong muscles, "No. I can't" Aoi said making Inosuke stare at her. "WHAT!? WHY NOT!?" Inosuke said getting frustrated. "I don't want to get you or me in trouble. Besides I'll get in the way" Aoi said as she looked away staring at the ground the towel she brushed the dust off of still in her arms.

"No you won't! I'll keep you in a safe place to hide and far enough away so you won't get spotted! If you get spotted, don't worry! I'll protect you with my life!" Inosuke said taking her shoulders and making her look at him. She got lost in his eyes and his words pierced her heart like a knife. But this knife was welcoming and she enjoyed it stabbing her heart. "I-I don't know, Inosuke. I'm not capable of helping or being able to fight demons" Aoi said as she looked away from him. "I'm taking you with me and your going to like it!" Inosuke said determined. Aoi thought it over and finally she sighed, Fine, I'll go" Aoi said as she finally looking at his eyes. "Great!" Inosuke said as he smiled greatly towards Aoi who blushed at his remark.

Later that night

"Hahahaha! Found you!" Inosuke said as he spotted the demon. It spotted him in the trees and got ready for his attack. "HAHAHAHAHA! PREPARE TO BE FALLEN BY THE GREAT INOSUKE!!!" Inosuke said before charging at the demon. "PIG ASSAULT!" Inosuke yelled as he started slashing at the demon. The demon and boar fought for a long time, Aoi was watching from the bushes. She was amazed at how he fought, he fought with elegancy at times despite being the type of person to be all just major slashes and nothing that graceful. When Inosuke was thrown at a tree he had a hard time getting up, the nurse instinct inside of Aoi kicked in causing her downfall considering she got out of her hiding spot to check on him.

"Oh, hello there little one" The demon said with a crooked smile. She stopped in her tracks not knowing what to do. "Move!" Inosuke yelled as he charged towards her trying to protect her. But it was to late as the needles infected with the blood able to turn a human to demon. And within 5 seconds the effects started to happen and Aoi started to experience excruciating pain all throughout her body as she flopped around like a fish. Her K-9's started to get bigger, her nails grew longer, she grew blue colored spots along her face. Her skin turned a midnight black, Inosuke didn't know what to do but stare and watch as his comrade turned into the very thing he swore to destroy. She then emitted grunts and growls as she started to take part in her new form. She looked up at him and bared her fangs at him and her eyes turned to slits. Inosuke just backed up, "Soai... it's me, Inosuke" Inosuke said trying to get her to calm down and to have a talk.

       She just kept lunging at Inosuke not caring at being friends with him, "AOI, LISTEN!" Inosuke yelled and she stopped in her tracks. She was bewildered that he said her name correctly. "Come with me! Please! I hate seeing you like this! We can turn you back!" Inosuke said fighting back many tears. Aoi saw this and she walked up close to him and did something he never would have thought. She hugged him and rubbed his back, the caring side of her kicking in overriding the demon inside her.

End of flashback

       "Inosuke we would like to speak to you" Shinobu said as she and the Master opened his door and walked in. "What is it?" Inosuke said to them, "We have a job for you" Ubuyashiki said as his smile was the same as ever. "What is the job?" Inosuke said as he tilted his head wiping the little tears he had. "You will take care of Aoi from now on until she turns back" Shinobu said as Aoi appeared from out behind the 2 higher rankings. "Really?" Inosuke said as he looked at Aoi curiously. "Yes. Now she will be staying in your room when she sleeps" Ubuyashiki said as she walked into his room and sat next to him leaning into him and started to fall asleep. "We will leave you two alone now" Shinobu said as they left the room and shut the door.

       Inosuke looked at Aoi fast asleep next to him and he pulled her close. He whispered to her in a calming and gentle way and said, "Don't worry, Aoi. I'll protect you until you turn back. I'm not leaving you" Inosuke said and she snuggled up to him tighter making him smile.
