AN: My take on how Nezuko is just one of many female demon slayers who Masao Maeda makes an outfit for.
Nezuko looked down at herself and tried to convince herself that she wasn't as self-conscious about her outfit as she really was. She pulled and tugged at the fabric of her top as she tried to button it once more and then gave up. She already knew the skirt couldn't be pulled down anymore if she didn't want to risk it falling off. She couldn't actually believe this was the female uniform for the demon slayers–Giyu's uniform hadn't prepared her and the lack of warning from him and Sakonji left her irritated.
"Alright," Nezuko sighed. "You can look, Tanjiro."
Tanjiro turned around and looked her over. Within seconds he was in front of the door with a mulish expression on his face and his arms crossed. He obviously wasn't interested in her leaving the room as she looked now.
"I don't like it either," Nezuko assured him. "I'll see if I can't at least get a better top, okay?"
The look on his face told her it was very much not okay. Normally Tanjiro acting in any way similar to how his human self would have acted made her happy, but right now she just found it mildly embarrassing because of why. She went to walk around him but then he turned the puppy eyes on her and she couldn't stop herself from patting his head. Those eyes trapped her as effectively as him holding her in place would have.
"Nezuko!" Sakonji called, "How long is it taking you?"
"Tanjiro won't let me out!" Nezuko called back.
"Let her out, Tanjiro!"
Tanjiro sulked but did as Sakonji ordered, just moving to the side with a pout since he knew he couldn't actually leave the room when they had a guest over. Nezuko stepped into the main room to find things just as she left them: Sakonji and the kakushi who had delivered her outfit, Masao Maeda, were sitting across from each other and sharing a cup of tea. Giyu sat just to Masao's right with the same bored look he'd been wearing when she left the room.
"You couldn't have warned me about the female uniform beforehand?" Nezuko complained, more in an attempt to hide her embarrassment than to actually complain. "M'still growing and this top is already tight. Do I get an extra one later?"
They all turned to look at her. Three sets of eyes went from her toes up, but only two made it to her face. As soon as Giyu met her gaze he reached over and shoved Masao's face into the tatami flooring. There was a crack, but she couldn't tell if that was from Masao's glasses breaking or just from how hard Giyu had shoved his face into the floor.
Nezuko gaped, shocked by the sudden violence, but then she caught herself and remembered what Sakonji had drilled into her. She inhaled to pick up all their scents and figure out what was going on. Giyu smelled of winter and anger, Sakonji smelled of still water and bloodlust, and Masao… she crossed her arms over her chest to cover herself, suddenly feeling far more exposed than she had just seconds ago. Sakonji stood up and came over to her, positioning himself so that he blocked her from view.
"Cover your ears," Sakonji told her.
She'd learned not to question him, so she covered her ears without complaint. He placed his hands over hers to ensure she couldn't hear well at all and with the way he was standing he blocked her view of the rest of the room–but that didn't stop her from picking up the acrid stench of fear from Masao. As each minute passed she actually began to feel a little bad for him, which helped assuage some of her anger.
It took five minutes, but Sakonji finally uncovered her ears and stepped away. Masao was nowhere to be seen and Giyu was just walking in the door of the hut, wiping something off his blade that she didn't look too hard at. She dropped her arms to her sides, knowing that neither of them would ogle her like Masao had and feeling less exposed because of it. The expression of anger on Giyu's face wasn't one she'd seen before and it made her feel all warm and tingly inside.
She caught Sakonji's eye and adopted her best innocent expression, "Is it because he didn't measure me right? I guess my breasts could have slipped out if I moved too fast…"
"Or if you breathed," Sakonji tacked on dryly.
Nezuko bit her lip, glancing over at the pained look on Giyu's face and enjoying it enormously. Messing with him didn't magically make all the bad feelings go away, but it helped things feel more normal and she knew he'd let her get away with it. It was nice to know that she had a family outside of Tanjiro that she could still tease and joke around with when she wanted to ignore everything else.
"I can't believe you actually thought we made female demon slayers wear that," Giyu grumbled.
"How was I supposed to know?" Nezuko frowned, "I've only seen your uniform and Ojiichan-" she ducked a hit across the head from Sakonji with ease, "-said I could choose between pants and skirt, so I figured the skirt must just be that short. I thought it made sense! Most demons prefer women and this outfit is certainly… alluring. I figured it was either meant as a distraction technique or as a way to lure more of them out. And it was given to me by a kakushi, so I thought I was supposed to trust it!"
"If any kakushi tries to get you to wear something like that again, send them my way," Sakonji said.
"Now that I know better I'll handle it myself," Nezuko promised. Sakonji had trained her well enough for him to believe her when she said it, "It's just good that neither of you had anywhere pressing to be right now, if I'd gotten this on my own and not known I would have been stuck wearing it out of embarrassment!"
Giyu's pained look transformed to one of mild horror, "Can you help me write an apology letter, Nezuko-chan?"
"Huh?"
"I need to apologize to Konroji-san," he informed her sullenly.
