Gratefulness

Quick idea from the Sever that gave me the head canon for my fic 'Movies'.

I hope you enjoy!

Hashibira Inosuke was not hurt.

That's what the Breath of the Beast user would say every time he was sent to the Butterfly State because of an injury and every time, it would be a complete lie.

Injuries were not uncommon for Demon Slayers and when they were sent to the Insect Pillar's home, the corps' unofficial hospital, it's because those injuries require serious treatment and not something that any doctor could treat; at least not to the level or the speed that the members of the Butterfly State could.

"For the last time, you need to stay in bed and rest." Then there was the other issue, this girl that thought she could order him around.

"You can't tell me what to do." Inosuke answered glaring at her from behind the eyes of his boar mask.

Kanzaki Aoi, the head nurse, according to Monitsu, of this place.

Whenever he was here she tried to make him stay in bed to recover with varying levels of success.

There was one time she physically tied him to the bed, it took a while due to the injury at the time but he managed to break free and continue being his usual boisterous self.

So far, the only time he had obediently shut up and listened to her, that time after the Natagumo Mountain notwithstanding, was when she had taken his boar mask at night to wash it because 'it smelled terrible', her words, and after constantly repeating to her to give it back she said that she would give it back when it's washed and he has had a proper rest to recover from his injuries.

Inosuke did try to kick up a fuss about it but she said that he either agrees or she'll hide his mask in a place he will never find it so he ended up listening.

"For the love of... you do realize that you have at least five broken ribs and some internal bleeding that we just stopped, right?" Aoi questioned while pinching the bridge of her nose.

"If my bleeding is internal then I'm fine, that's where blood is supposed to be!" He countered, smiling smugly behind his mask.

"Not like that!" She yelled back before sighing. "Do I have to take your mask from you so you will listen?"

"...what makes you think I'd let you?" He said, trying to sound challenging and if anyone had to guess, they would say he was narrowing his eyes behind his mask.

"The fact that if you try to run, I just have to chase you until your wounds act up to take it, then I will have to check your injuries again and apply treatment depending on how bad they've gotten because you refused to rest." The black haired girl answered with a glare before sighing. "Just... please don't hurt yourself anymore and rest, you already get enough injuries in battle." She added with a softer expression.

Inosuke stood still after hearing that and, for a second, Aoi thought that he would ignore her warnings and try to get away from her, she was already in position to try and grab his mask before he could run too far so he wouldn't worsen his condition; although he will probably just try to catch her and she would need to run until his wounds acted up, therefore making the entire thing pointless but if there was a chance of losing him quickly and hiding the mask so he would listen and not injure himself, then Kanzaki Aoi would do her best to take it.
