Chapter Text
Kanae’s voice echoed through the room, unusually sharp.
“What on earth are you doing here again?”
Sanemi sat on one of the treatment beds in the Butterfly Estate, his upper body bare. A long, ugly wound stretched across his chest, dark and raw, and his arm bore another deep gash that looked just as unpleasant. Kanae stood in front of him with her hands on her hips, clearly demanding an explanation.
He had been here barely a week ago. Not treated by her directly, but by one of her girls. That alone made this whole situation… uncomfortable.
“Got injured again,” he muttered, as if it were nothing.
The pain was annoying, sure, but hardly worth mentioning. If it had been up to him, he would have rested for a day at his newly assigned estate and been done with it. But the Master had insisted.
She’s incredibly intelligent. She knows exactly how to treat these wounds.
And so he had been sent straight to the Butterfly Estate.
Now he sat there, feeling oddly self-conscious. To him, these injuries barely counted as anything worth fussing over.
“Yeah,” Kanae replied, sighing as she stepped closer, stopping only a few inches away from him. “I can see that.”
The air between them felt thick. Tense. Sanemi immediately caught her floral scent and had to force himself not to look into her violet eyes. Instead, he turned his gaze away.
Kanae placed a hand on his chest.
Her fingers were soft. Light. Delicate.
Outwardly, he didn’t react. Inwardly, his pulse jumped sharply. There was something there—something unspoken, lingering between them.
“I really don’t understand you,” she said, reaching for a cloth and a bowl of water to clean his wounds. “You’re a Hashira now. Shouldn’t you be at least a little more careful?”
He wasn’t the only one who felt the tension. Kanae did too.
Ever since that kiss half a year ago—alone in her room, arms wrapped around each other—they hadn’t spoken of it. Not once. They had simply carried on as if nothing had happened. Missions. Battles. And eventually, both of them becoming Hashira.
This was the first time since then that they were truly alone.
The memory refused to leave her mind. It had been her first kiss, and heavens—Sanemi had stolen her breath away. He had been bold, almost reckless, yet somehow gentle and warm all at once. She had melted against him, and even now, just thinking about it made her heart race.
She pressed her lips together as she carefully cleaned his wounds, the room falling into silence. She wondered if she should say something. Anything.
“Sorry,” Sanemi finally muttered, quietly.
He knew she had better things to do than patch him up.
Her eyes narrowed when she noticed the faint purple discoloration around the wound on his chest. “You were poisoned,” she said, clearly displeased. “What kind of demon was it?”
She turned toward a cabinet, searching for a specific antidote.
“Nothing special,” he shrugged.
The less he said, the better. Or so he thought. Somehow, it only seemed to irritate her more.
“That doesn’t help at all,” she snapped.
To his own surprise, he realized he liked the sound of her sweet voice when it carried anger.
“Look, I don’t need treatment,” he said. “I’m fine. These are just some scratches, I—”
“Fine?” she cut him off. “Didn’t you listen to me? You were poisoned, Sanemi! It’s going to rot your flesh. You must be in so much pain…”
Her voice softened with every word.
The sympathy in her tone made him uncomfortable. He didn’t want pity. He was fine—or at least he wanted to believe he was.
“You’re overreacting,” he dismissed her.
“No, I’m not,” she shot back. “You’re stubborn. And incredibly stupid if you really think you can just leave it like this.”
Her hands were rougher now as she worked on the wound. She pulled a chair closer and sat down right in front of him, her fingers—still soft, still gentle—moving over the injury again.
He let out a short, pained sound when she brushed the infected area.
“Yeah,” she muttered, irritated. “Sure. You’re fine.”
So stubborn.
Sanemi pressed his lips together, refusing to meet her gaze.
“Do whatever you want,” he said calmly.
“Let me see your arm,” she demanded.
He complied, thankfully without protest. She immediately noticed the difference—this wound was cleaner, far less severe than the one on his chest.
Kanaes fingers lingered on his arm longer than necessary.
This wound was different. Cleaner. Controlled. It told a story of precision rather than recklessness—and somehow, that unsettled her even more.
“At least this one was done properly,” she murmured, more to herself than to him. “Which means you can be careful when you want to.”
Sanemi scoffed quietly. “Don’t read too much into it.”
She didn’t answer right away. Instead, she dipped the cloth into fresh water and cleaned the cut with steady hands. She was close now—close enough that he could feel the warmth of her body, close enough that her hair brushed his shoulder whenever she leaned in.
Too close.
He clenched his jaw.
“You know,” she said softly, breaking the silence, “it wouldn’t kill you to admit when something hurts.”
He huffed a humorless laugh. “Coming from a healer, that’s rich.”
Kanae glanced up at him then, finally meeting his eyes. Her expression wasn’t angry anymore. It was something else—concerned, searching, threaded with an emotion she didn’t dare name.
“I’m serious,” she said. “You don’t have to carry everything alone.”
That did it.
Something in his chest tightened painfully, far worse than the wound she was treating. He looked away again, staring at the wall as if it could offer him refuge.
“You sound like the Master,” he muttered.
“Maybe,” she replied quietly. “Or maybe I just care.”
The words hung between them, fragile and dangerous.
Kanae finished bandaging his arm and leaned back slightly, exhaling as if she’d been holding her breath the entire time. For a moment, she simply watched him—his tense posture, the way his shoulders were always drawn tight, as if he were bracing himself for a blow that never came.
“You haven’t changed,” she said, almost fondly. “Not even a little.”
Sanemi frowned. “That supposed to be an insult?”
Her lips curved into a faint smile. “No. Just an observation.”
She stood, turned away to put the supplies back, and for a second he thought—hoped—that would be the end of it. That the space between them would settle back into something manageable.
But when she turned around again, her expression was serious.
“You scared me,” she admitted.
He stiffened. “I was injured. That’s part of the job.”
“That’s not what I mean,” she said. “Seeing you here again. Like this. I keep thinking—what if one day you don’t walk back through that door?”
His breath caught before he could stop it.
For the first time since he’d arrived, he looked at her properly. Really looked. At the tension in her shoulders, the worry she was trying so hard to keep contained, the way her hands trembled just slightly at her sides.
“…Kanae,” he started, then stopped.
He didn’t know what to say. He wasn’t good at this.
At feelings. At things that mattered too much.
She swallowed, then straightened, as if bracing herself. “You should rest after this. I’ll prepare something for the poison, and you’re not leaving until I’m sure it’s working.”
He opened his mouth to argue—then closed it again.
“…Fine,” he said gruffly. “But don’t expect me to enjoy it.”
Her smile this time was real. Small, but warm. “I wouldn’t dream of it.”
As she stepped past him, their hands brushed—just barely.
It was an accident. It had to be.
And yet neither of them moved away immediately.
The silence that followed was thick, heavy with everything they still hadn’t said—and everything they both remembered far too clearly.
For a moment, Kanaes touch on his arm pulled him somewhere else entirely.
Back then…
It had been late—far too late for visitors—and Sanemi hadn’t even been the one meant to stay. He’d only brought another Demon Slayer to the Butterfly Estate, someone far worse off than he was. A quick handoff. That had been the plan.
He remembered walking down the dimly lit corridor, the quiet hum of the estate wrapped around him like a held breath.
And then she had appeared.
Barefoot. Hair loose. Already dressed for sleep.
Kanae had stopped short when she saw him, surprise flickering across her face—followed by something lighter. Softer. Amused.
“You’re still awake?” she had asked.
He’d shrugged, grinning in that rare, easy way he only ever did when his guard slipped. “Could say the same about you.”
They had talked. About nothing. About everything. A few careless jokes, a few teasing remarks that came too easily. Too naturally. Sanemi had been in an unusually good mood that night—light, almost—and Kanae had laughed more than she meant to.
At some point, she had taken his hand.
Not hesitantly. Not nervously.
Just… like it was the most natural thing in the world.
He still remembered the warmth of her fingers around his wrist as she pulled him down the hallway, her laughter hushed but bright as she led him into her room.
They hadn’t planned anything. There had been no intention behind it.
They had just stood there at first—too close, suddenly aware of the space between them shrinking to nothing.
Sanemi remembered teasing her about the way her heart was racing. Remembered how she’d rolled her eyes and told him he was imagining things.
And then—somehow—he had leaned in.
He could still feel the way she’d frozen for half a second, breath caught, before she kissed him back.
Soft. Uncertain. Real.
It had startled him how quickly it had deepened—not into something wild or reckless, but into something earnest. Honest. Like they were both afraid it might disappear if they didn’t hold onto it.
They had ended up on the edge of her bed, still kissing, laughing quietly between breaths, hands awkward and careful as if neither of them quite knew what they were allowed to do.
Kanae had been smiling when they finally pulled apart—cheeks flushed, eyes bright, utterly undone.
And then reality had come rushing back…
They hadn’t spoken about it afterward. Not once.
They’d gone on missions. Fought demons. Earned their titles. Stood side by side as Hashira, as if nothing had ever happened.
As if that night had never existed.
Sanemi swallowed, the memory tightening something deep in his chest.
Standing here now, with Kanae’s hands steady on his skin and that same unspoken tension humming
between them, he realized—It hadn’t faded.
Not for him.
And judging by the way her fingers trembled ever so slightly as she worked, not for her either.
Sanemi watched her.
The way her brows furrowed in concentration. The careful precision of her hands, gentle even when she was clearly annoyed with him. It struck him—again—how much effort she put into everyone else. How little she ever seemed to demand in return.
Idiot, he thought.
Not at her. At himself.
Back then, he had left without saying anything. Had pretended it hadn’t mattered. That the kiss hadn’t lodged itself somewhere deep in his chest, stubborn and unyielding.
And now here they were—alone, for once—and the air between them felt exactly the same. Heavy. Expectant. Like something was waiting to be acknowledged.
“Hey,” he said suddenly, his voice quieter than before.
Kanae paused, looking up at him. “Yes?”
He hesitated. For half a heartbeat, he nearly backed down. Old habits tugged at him, urging silence, urging restraint.
“…Thanks,” he muttered instead. “For… taking care of it properly. I know I’m not exactly an easy patient.”
Her expression softened.
“You’re welcome,” she replied gently, though her fingers lingered just a little longer against his skin before she pulled away.
Silence settled again—thicker now. Charged.
Sanemi could hear his own heartbeat, loud in his ears. He was painfully aware of how close she still was, how her scent curled around him like something familiar and dangerous.
If he didn’t do something now, he never would.
Before he could overthink it, he reached out—slowly, giving her time to pull away if she wanted to.
She didn’t.
His fingers brushed her wrist, tentative. Almost uncertain.
Kanae inhaled sharply, her eyes flicking to his hand… then back to his face.
For a moment, neither of them moved.
Then Sanemi leaned in.
Not rushed. Not forceful.
Just enough.
Their lips met—softly this time, careful and brief, like a question neither of them dared to voice. It was nothing like the first kiss had been. Less reckless. More aware.
When he pulled back, he didn’t say a word.
Neither did she.
Kanaes cheeks were faintly flushed, her gaze unreadable but warm. She didn’t step away. Didn’t scold him. Didn’t ask what it meant.
She simply offered a small, quiet smile.
And somehow, that felt like enough.
For now.
By the time Sanemi had left the Butterfly Estate, the sun was already sinking low behind the trees.
Kanae tried not to think about the way his lips had felt—or about the fact that they hadn’t talked about it. Again.
Instead, she focused on the present.
Gyomei had arrived shortly after, his presence calm and grounding as always. He sat patiently at the low table, hands folded, quietly waiting while Kanae and Shinobu prepared tea in the adjoining room. The evening was peaceful on the surface, the soft clink of porcelain and the gentle sound of boiling water filling the space.
Too peaceful.
Shinobu watched her sister closely as they worked side by side.
Kanae moved with her usual grace, but something was… off. Her smiles came a fraction too late. Her thoughts clearly somewhere else.
Shinobu narrowed her eyes.
“So,” she said casually, reaching for the teapot. Far too casually.
Kanae hummed in response, distracted.
Shinobu leaned a little closer. “The Wind Hashira was here earlier, wasn’t he?”
Kanaes hand stilled.
“…Yes,” she answered carefully.
Shinobus eyes lit up. “Did something happen?”
Kanae blinked. “What? No— I mean—” She stopped herself, heat rushing to her face. “Why would you think that?”
Shinobu tilted her head, studying her sister with unsettling sharpness for a thirteen-year-old. Then, far too innocently, she added:
“I’ve seen you two before.”
Kanae froze.
“…Seen us?” she echoed faintly.
Shinobu nodded. “A while ago. Late at night.” She shrugged. “Your door wasn’t fully closed.”
Kanae felt her heart drop straight into her stomach.
“Oh,” she breathed, mortified. “Shinobu, I— it wasn’t—”, she started, blushing.
“I know,” Shinobu interrupted quickly. “I didn’t tell anyone.” She paused, then looked up at her sister more seriously. “But… was it like that again today?”
Kanae opened her mouth.
Closed it.
She honestly didn’t know how to answer.
…there had been something. A moment. A kiss.
But what was it?
“I don’t really know,” Kanae admitted quietly. “We…uhm…”
Shinobu frowned.
She placed the teacups down with a little more force than necessary and crossed her arms. “You should be careful.”
Kanae turned to her, surprised. “Careful?”
Shinobu nodded firmly. “He’s always so aggressive and mean.”
The words were blunt. Childishly honest.
Kanae smiled softly despite herself. “He’s not always like that.”
Shinobu wasn’t convinced. “Maybe not with you,” she muttered. Then, more quietly: “But still.”
Kanae reached out, gently smoothing a hand over Shinobus hair. “Thank you for worrying about me.”
Shinobu huffed but leaned into the touch just a little. “I just don’t want you to get hurt.”
Kanaes smile softened—then faded slightly.
Neither did she.
With the tea ready, they carried the tray back to the main room, where Gyomei waited patiently, unaware of the quiet storm that had just passed through the air.
Kanae sat down, hands folded in her lap.
And for the first time that evening, she allowed herself to wonder—What exactly had she started… and where would it lead this time?
Gyomei had noticed it the moment he entered the Butterfly Estate.
Sanemi had been there already—standing far too stiff in the courtyard, arms crossed, gaze fixed somewhere that wasn’t quite the path ahead of him. For a man who usually carried himself like a sharpened blade, he had looked… unsettled. Restless.
Gyomei had greeted him quietly. Sanemi had answered just as briefly, but there had been something in his voice—strained, almost impatient, as if he were trying to outrun his own thoughts. He had left soon after, steps too quick, shoulders tight.
Ah, Gyomei had thought then.
Now, seated at the low table with a warm cup of tea between his hands, that quiet certainty only deepened.
Kanae returned to the room with Shinobu, her movements still gentle, still kind—but no longer quite as effortless as usual. There was a softness in her expression that hadn’t been there before, a distant glow behind her eyes. She listened attentively, smiled warmly, yet her thoughts seemed to drift just a fraction too often.
Gyomei did not need sight to notice these things.
He felt them.
The air around Kanae was different. Lighter. Charged.
Shinobu spoke animatedly beside her, far too cheerful for someone who had just tried to sound casual moments earlier. Gyomei listened without interrupting, his face calm, serene. He did not ask questions. He did not pry.
But inwardly, he smiled.
He remembered Kanae and Shinobu how they had been when he found them—small, frightened, clinging to each other with everything they had left. He remembered the promise he had made then, quietly, solemnly.
I will protect you.
Seeing Kanae like this—still strong, still compassionate, yet touched by something undeniably human—filled him with a warmth he rarely allowed himself to dwell on.
Sanemi Shinazugawa was a storm of a man. Sharp edges, rough words, too much pain carried too close to the surface.
But Gyomei had seen that look before.
Not on Sanemi—but on men who had fallen in love without knowing what to do with it.
Kanae set a cup down in front of him, her smile gentle. “Is everything to your liking, Himejima?”
“Yes,” he answered softly. “Very much so.”
He paused, then added, almost thoughtfully, “It is good to see you well.”
Kanae blinked, then smiled a little wider. “Thank you.”
Gyomei inclined his head, content to leave it at that.
Some things did not need to be spoken aloud.
Still, as the evening wore on and the tea slowly cooled, Gyomei found himself quietly pleased. If those two stubborn souls were finally circling closer—fumbling, silent, unresolved as it might be—then perhaps the world had not taken everything from them after all.
And for now, that was enough.
Kanae excused herself only briefly—just long enough to fetch something from the adjoining room.
The door had barely slid shut behind her when Shinobu turned on Gyomei.
Not subtly.
Not patiently.
She leaned closer, violet eyes sharp with concern, her small hands wrapped tightly around her teacup.
“Himejima,” she said in a hushed but urgent whisper, “do you know what happened earlier?”
Gyomei did not answer at once. He lifted his cup, took a slow sip, and set it back down with deliberate calm.
Shinobus brow furrowed.
“You saw him, didn’t you?” she pressed on. “Sanemi Shinazugawa. He was here.”
A pause.
“Yes,” Gyomei replied gently. “I did.”
Shinobus lips pressed into a thin line. “He’s always like that,” she muttered. “So… aggressive. He looks at me like I’m in his way.” Her fingers tightened around the porcelain. “I don’t like him.”
Gyomei turned his head slightly in her direction. “That is understandable.”
She blinked, surprised. “You’re not going to defend him?”
“No,” he said simply.
That only made her more serious.
“Then you agree he’s dangerous,” she said quickly. “Not as a swordsman—but as a person. Kanae is too kind. She always sees the good in people, even when they don’t deserve it.”
Gyomei was quiet for a moment.
“Sanemi carries much anger,” he said at last. “And much grief.”
Shinobu scoffed softly. “So do a lot of people. That doesn’t mean he gets to—” She stopped herself, huffing. “He makes her nervous. I can see that.”
Gyomei inclined his head slightly. “You are very observant.”
Shinobus eyes narrowed. “So you noticed it too.”
“Yes.”
“…what do you know about them?”
The question hung in the air—small, sharp, impossibly earnest.
Gyomei folded his hands together in his lap. “I believe,” he said carefully, “that something is happening. Whether either of them understands it yet is another matter.”
Shinobu stared at him.
Then—“That doesn’t sound good.”
Gyomei allowed the faintest hint of a smile.
“Why?” he asked.
“Because Kanae will try to be patient,” Shinobu said immediately. “She’ll wait. She’ll make excuses. And he—” She frowned deeply. “He doesn’t look like someone who knows how to say what he feels.”
“That,” Gyomei agreed softly, “may be true.”
Shinobu sighed, resting her chin briefly on her hands. “…If he hurts her, I won’t forgive him.”
Gyomei turned fully toward her now, his voice warm, steady. “Nor will I.”
She looked up at him, surprised again—then nodded, reassured.
“…Okay,” she said quietly. “Then… keep an eye on her, please.”
Just then, the door slid open again.
Kanae returned, smiling as always, unaware of the silent pact that had just been formed in her absence.
Shinobu straightened immediately, plastering on an innocent expression.
Gyomei lifted his teacup once more.
And somewhere far from the Butterfly Estate, a certain Wind Hashira had absolutely no idea how close he was to being thoroughly, silently judged.
The night air was cold.
Sanemi stood on the roof of his estate, arms crossed, staring into the darkness beyond the trees. The cicadas were loud, relentless—far too loud for his liking.
He exhaled sharply through his nose.
Idiot.
Kanaes hands wouldn’t leave his mind. Soft. Careful. The way her fingers had lingered just a second longer than necessary as she’d cleaned his wound. The way her voice had softened when she’d realized how much pain he was actually in.
And that look.
That quiet, searching look she’d given him when he’d finally thanked her.
He clenched his jaw.
He should have said more.
He almost had.
“Tch.”
He turned away from the edge of the roof, dragging a hand through his hair. This wasn’t the time. This wasn’t smart. He’d just been named a Hashira. He had responsibilities now. Missions. Expectations.
And Kanae…
She deserved someone steady. Someone gentle.
Not someone like him.
Still, as he lay down inside, staring up at the ceiling in the dark, her scent seemed to cling to him—flowers and clean linen, impossibly soft.
Sanemi shut his eyes.
“…Damn it.”
Somewhere else, under the warm roof of the Butterfly Estate, Kanae lay awake too, fingers brushing her lips, heart beating just a little too fast for sleep.
And neither of them knew it yet—but something had already begun.
