When the Burning Tree Blooms

Summary:

Memory, Atsu knows better than most, clings stubbornly to places and the heart. But so, too, do the living.

Notes:

I finished the game a couple of weeks ago and loved it. Atsu and Oyuki's complicated dynamic was so compelling that this idea just didn't leave me, and I had to write it.

Thanks T for the beta read as always<3

Chapter 1: Chapter One

Chapter Text

The first strange thing Atsu notices about peace is how noisy it is. 

Not battle-noisy. Not the sharp crack of gunfire or the scream of blade meeting blade, and definitely not the thud of bodies hitting solid earth. Peace has smaller sounds, softer ones, and they reach Atsu in places the old violence never could. Water simmering in a pot, wind worrying the eaves, the broom bristles whispering dust across the floorboards, someone moving outside without trying to hide it.

At first, it makes her skin prickle. For too long, every sound has meant threat or warning. Now morning comes with crows in the trees, Kiku singing tunelessly while she guts fresh caught salmon, and Oyuki stepping through the yard with an armful of split kindling. There's no immediate danger in any of it; nothing to kill; nothing to outrun. 

It should feel like a relief to Atsu, but instead, it feels like standing on unfamiliar ground and testing each plank before she puts her weight down.

𖣂˚⊱ ❀ ⊰˚𖣂˚⊱ ❀ ⊰˚𖣂˚⊱ ❀ ⊰˚𖣂

Six months after Saitō falls, snow still lingers in the shadows of the hills. The world is thawing by degrees. The paths through Teshio Ridge are all mud and slush; old blood has long since washed out of the earth, but Atsu still remembers where things happened. Here, a body fell. There, a horse screamed. Up that rise, a man begged. Down by the birches, she herself knelt in the snow with her hands shaking so badly she could barely close them.

Memory, Atsu knows better than most, clings stubbornly to places and the heart. But so, too, do the living.

Kiku hangs freshly gathered herbs to dry beneath the eaves, complains about stubborn pots with soot that won’t budge no matter how hard she scrubs and the attitude of the chickens as they brazenly escape from their designated enclosure. Sometimes, she even helps to repair the netting with her small, competent hands; a deep furrow knitting between her brows as she works—it settles in such a way that it screams Jubei, and Atsu feels her breath lodge momentarily in her throat. 

Villagers come and go with requests, rumours, and awkward gratitude, bowing to Atsu as if she’s something holy or dangerous or, perhaps, both. Atsu hates that look they carry; hates that some part of her still straightens under it. The Onryō is dead. She’s told herself that enough times to wear grooves in the thought. The mask is buried. The katana are displayed decoratively on the wall as if they’ve never been used. And yet… the name follows her anyway.

Sometimes, when waking, Atsu still reaches for its shape. Sometimes she walks half the morning before realising she’s taken the old habits with her: her body keeping to shadow, her eyes checking rooftops and ridge lines, her hand hovering near the katana she no longer wears and no longer needs every minute of the day.

And always, in the strange shape of this continued life, there is Oyuki.

Not beside her every hour. Not close enough to be a comfort she can lean on without thinking. Oyuki isn’t soft in that way, and Atsu isn’t sure she would know what to do with softness if it were offered too freely. But Oyuki is there: mending fencing in the yard, speaking low with Kiku over seed stores, disappearing into the woods to set snares and returning with rabbits or clusters of berries or damp mushrooms and a face sharpened by the wind.

Alive. Real. Not an enemy. Not a ghost.

Some days, to Atsu, that still feels like the most impossible thing of all.

𖣂˚⊱ ❀ ⊰˚𖣂˚⊱ ❀ ⊰˚𖣂˚⊱ ❀ ⊰˚𖣂

On one particular morning washed pale with mist, Atsu comes back from the ridge with a basket of fish and mushrooms, and finds Oyuki sitting on the engawa with her sleeves pushed up, and a bucket of hot water at her feet. 

There’s blood on her knuckles, and Atsu stops in the yard before she can help herself. ‘What happened?’ she exhales as she eyes the wound.

Oyuki glances up. ‘Fence post.’

Atsu looks from the split skin across her hand to the hammer lying nearby. ‘The fence fought back?’ she quips.

A small smile touches Oyuki’s mouth, brief as a moth’s wing. ‘It lost in the end.’

That smile still catches Atsu wrong. Not painfully, but acutely; like something in her chest tightening around a wound that hasn’t decided whether it wants to heal fully.

She sets the basket down. ‘Let me see.’

Oyuki’s eyebrows lift, but she holds out her hand for Atsu to take. The cut isn’t deep, and thankfully, Atsu has had plenty of practice stitching worse on herself with numb fingers and bad lighting. Even so, she keeps her touch careful when she cleans the blood away. Oyuki’s skin is cool from the morning air, then warm when the water runs over it. 

There’s an intimacy in this that Atsu doesn’t quite know how to name. Not because tending wounds is new to her, it isn’t by any means; she has touched blood and pain all her life, but usually there’s urgency in it, a brutal necessity. This, however, is different. This is just her and Oyuki and a fence post and steam curling off a bucket between them.

‘You’re frowning,’ Oyuki says quietly.

‘I always frown,’ Atsu counters lightly.

‘No.’ Oyuki watches her, too perceptive by half. ‘Not like this.’

Atsu keeps her eyes on the cloth in her hand. ‘Like what?’

‘Like it matters to you,’ Oyuki answers astutely.

The words land more softly than they should, which only makes them harder to bear. Atsu binds the cut with clean linen, perhaps more tightly than needed, but Oyuki doesn’t complain. When she finishes, Atsu starts to draw back, but Oyuki turns her hand over and catches Atsu’s wrist for a moment—barely a touch, just fingertips against Atsu’s pulse.

‘Thank you,’ she says earnestly.

Atsu nods once in acknowledgement and then gently pulls away. She retrieves the basket as if she hasn’t felt that brief contact all the way down to the soles of her feet, and the two of them continue their day as though they’re not purposefully dancing around each other.

𖣂˚⊱ ❀ ⊰˚𖣂˚⊱ ❀ ⊰˚𖣂˚⊱ ❀ ⊰˚𖣂

The first time Oyuki laughs in front of her, properly laughs, Atsu nearly misses it.

It happens at dusk after a sudden spring rain. Kiku is cursing because one of the hens has gotten into the drying herbs again when Atsu steps inside with mud on her sandals and rain dripping from her sleeves, and Kiku rounds on her with all the fury of a child betrayed by poultry.

‘If that bird eats one more bundle of yomogi, I’ll roast it, Aunt Atsu. I swear.’

‘You say that every week,’ Oyuki murmurs, sorting through the salvaged herbs.

‘And one week I’ll mean it,’ Kiku huffs.

‘No, you won’t,’ Atsu replies, and then, without thinking, whispers mockingly, ‘We all know you talk to them adoringly when you think no one hears you.’

Kiku gasps in outrage as Oyuki looks up. Then Oyuki laughs. It isn't loud. It doesn’t spill out of her unchecked. It breaks free as if it’s surprised even her, bright and low and unguarded, and Atsu feels it like a hand opening in the dark.

For one foolish second, she can only stare. Oyuki catches her looking and, just as swiftly, the laughter eases back into something smaller. Not entirely gone; the warmth of it stays in her face, in the corners of her molten eyes. It changes her. Or perhaps it reveals something that’s been there all along beneath grief, beneath guilt, beneath the old survival-sharpness both of them know all too well.

Atsu forces herself to look away first.

Later that night, she lies awake listening to rain tick against the roof and thinks, with a sort of exhausted disbelief, that she might be in deep trouble. Not danger, exactly, but something worse; something perilous that she doesn’t know how to fight through or survive unscathed.

𖣂˚⊱ ❀ ⊰˚𖣂˚⊱ ❀ ⊰˚𖣂˚⊱ ❀ ⊰˚𖣂

Spring moves over the land in fits and starts. The snow recedes, rivers fatten, and trails become passable once more. The roads' reopening brings an influx of people passing through, and with them, a new wave of problems. Outlaws testing old boundaries. Men still loyal to Saitō trying to reclaim the power that died with greater monsters. And even refugees from farther north carrying stories in their mouths like splinters.

Atsu still rides out when she must. She tells herself that’s all it is: a must. A duty to defend the people she helped free. She doesn’t ever wear the Onryō mask. She doesn’t need to; her name is enough now, spoken quietly from village to village. Sometimes that sickens her, and sometimes it saves time.

Once, returning at sunset with blood drying on her sleeve—where someone else’s blade has glanced off her—she finds Oyuki waiting outside before she has even dismounted.

‘You’re hurt,’ Oyuki says in place of greeting, her eyes crinkling with concern.

‘Barely,’ Atsu shrugs, always desperate to lighten the tension simmering between them, if only for her own sanity. 

Oyuki’s jaw tightens. ‘You say that too often, Atsu.’

Atsu means to brush past the comment. She’s tired, sore, and growing irritable with the whole shape of the day now, but Oyuki steps closer, looking at the tear in Atsu’s sleeve with a focus that feels almost like anger.

‘Sit,’ she commands, gesturing inside.

Atsu pouts. ‘I’m not a child.’

‘No,’ Oyuki counters swiftly. ‘You’re worse; you're stubborn.’

Atsu should snap back, but, absurdly, she finds her body obeying before her mind can catch up. Inside, the lamp burns low. Kiku has gone to a friend’s house and left a bamboo broth covered near the hearth. Oyuki kneels in front of Atsu with a basin, a clean cloth, and a medicinal salve made from the salvaged yomogi that smells sharp and green. Her hands are steadier than Atsu’s have ever been after a fight, and when Oyuki peels the sleeve back, Atsu sucks in a breath despite herself.

‘So,’ Oyuki says flatly. ‘This is barely?’

‘It looks more dramatic than it is,’ Atsu replies with another shrug.

‘I fear it looks as crude as the progression of my latest shamisen song,’ Oyuki jests.

Atsu huffs a laugh before she can stop it, and Oyuki glances up, startled by the sound. For a moment, they both go still, and Atsu feels how sudden and overwhelmingly charged the quiet can become.

Oyuki looks back down first and begins to clean the wound, applying the salve with careful fingers. Atsu watches the bowed line of her head, the dark sweep of her lashes, the loose strand of hair that keeps brushing her cheek. She has seen Oyuki bloodied, armed, and unmasked by old truths. She has even seen her weeping once, in the days after Jubei’s passing, when Kiku had been inconsolable, and Oyuki’s guilt had risen thick and fast and threatened to drown her. That memory remains in Atsu’s chest like a hidden blade; she knows how heavily Oyuki carries her regret. But this—this small domestic nearness, this anger born of concern—is somehow harder to face.

‘Why do you do it?’ Oyuki asks after a while.

Atsu knows what she means. Why ride out? Why still sometimes answer the whispers of trouble as if they belong to her? Why keep putting her body between danger and a world that has already taken too much from it?

Atsu swallows thickly and doesn’t meet Oyuki’s gaze for fear of what she might find in it. ‘Because someone has to.’

‘That isn’t an answer, Atsu,’ Oyuki murmurs sorrowfully.

Maybe it isn’t, but it’s the only one Atsu has ever allowed herself to have.

She says nothing in the end because it’s easier not to than to face the tangled feelings constricting tightly in her chest. Oyuki ties the bandage off with more force than necessary. Not enough to hurt, but enough to make a point.

‘You’re allowed to live now,’ Oyuki says, quiet and furious. ‘I thought you knew that?’

Atsu finally, slowly, meets her eyes.

There are many things she could say. That living and deserving aren’t the same. That some nights she still sees the faces of those she’s killed lined up behind her eyes when she closes them—Jubei’s the most. That revenge gave her a shape to inhabit, and without it, she sometimes feels as if she’s dissolving. That mercy is harder than murder. That being loved—if this is the road leading there, if this is what she is beginning to recognise in the way Oyuki looks at her—might be the most terrifying thing she has ever faced.

What comes out instead is, ‘I’m trying, Oyuki.’

Something in Oyuki’s expression changes, then, not softens, exactly, but opens like a flower unfurling beneath the warmth of the sun.

‘I’m glad,’ she says, and her hand remains around Atsu’s forearm for one heartbeat longer than necessary. ‘But please, try a little harder. You have so much to live for, Atsu.’

Atsu doesn’t speak; she just holds Oyuki’s gaze and nods in a silent promise. 

𖣂˚⊱ ❀ ⊰˚𖣂˚⊱ ❀ ⊰˚𖣂˚⊱ ❀ ⊰˚𖣂

Summer comes, and with it, heat that presses sweat into the back of Atsu’s neck and turns the fields gold-green. The world smells of tree resin, river silt, and crushed grass. Life swells everywhere; too bright, sometimes, and too full. Yet Atsu begins, slowly, to fit herself inside it.

She repairs the damage on the roof with Kiku and doesn’t feel foolish or useless for it. She teaches a farmer’s son how to hold a katana without chopping off his thumb. She sits outside in the evenings while the sky burns itself out over the ridge, and no longer reaches automatically for the nearest escape route. Instead, she lets her feel as much as she can while her fingers pluck an accompanying tune on her shamisen.

And always Oyuki is there, moving around the edges of her days until the edges aren’t edges any more.

There is no single moment it becomes love. Atsu wouldn’t trust such neatness even if it were offered. It gathers slowly instead. It’s in the way Oyuki leaves the plumpest berries in the bowl and says nothing when Atsu takes them. It’s in the way she knows, without asking, when Atsu needs silence rather than speech. It’s in the way Atsu, riding back from the valley, starts marking distance not by milestones but by how long until she sees smoke from home.

Home

The thought startles her every time; how true that’s starting to feel again.

𖣂˚⊱ ❀ ⊰˚𖣂˚⊱ ❀ ⊰˚𖣂˚⊱ ❀ ⊰˚𖣂

Late in the season, they spend a quiet afternoon alone together by her family's graves. It’s quiet beneath the ginkgo tree, and the wind combs through the grass and rustles the fresh flowers Kiku has tied to the remembrance post with string.

Atsu kneels first. She doesn’t pray. She never knows what to say to the dead that doesn’t sound inadequate. But she remains there in the long hush, hand resting in her lap, and lets memories of Mother, Father and Jubei come as they will.

When she rises, Oyuki is watching the horizon where Mount Yōtei sits in all its ethereal glory.

‘For the longest time, I thought revenge was all that was left for me,’ Atsu says, surprising herself with the confession. ‘Followed by the emptiness that would surely come afterwards.’

Oyuki turns to her. ‘And now?’

Atsu looks at the graves, at the sweeping landscape beyond their home; at the smoke from Yōtei’s Shadow inn in the distance, thin and blue against the evening, then back at Oyuki. And because she’s so unbelievably tired of cowardice wearing noble faces, she answers honestly.

‘Now I think emptiness leaves room for other things.’

Oyuki’s throat moves, and her eyes glisten hopefully. ‘Such as?’

Atsu almost smiles. ‘I think you might already know, Oyuki.’

A flush, faint and real, rises beneath the bronze skin of Oyuki’s face. Atsu has seen her draw her kusarigama without hesitation, hold secrets like knives, and survive what should have broken her. Yet somehow seeing her blush feels stranger than any battlefield ever has.

‘Perhaps I would like to hear you say it,’ Oyuki murmurs as gently as the breeze.

The wind stirs between them again, grass whispering around their ankles, and Atsu’s heart beats with the blunt, unreasonable force of a fist against a door. She has spoken threats more easily than this. Confessions have never been her language; want has always been dangerous when named. But she’s learned in the last—long—few months that life continues. It continues after blood, after fire, and after all the reasons it shouldn’t. It asks impossible things. It asks for tenderness from scarred hands. It asks for trust from those who have buried too much. It asks, sometimes, for a person to step forward without armour and call that courage too.

‘I think about you when you’re gone,’ Atsu says quietly, and Oyuki doesn’t move as her confession slips between them. ‘I look for you without meaning to. I know the sound of your step. I know when you’re angry or feeling guilty before you speak. I know when you’re lying about being tired.’ Her voice roughens, but she keeps going. ‘And when I come back from somewhere, I’m… relieved to find you still here. Every time. As if part of me still expects—’

Loss. Betrayal. Absence. Death.

Atsu doesn’t finish the thought. She doesn’t need to because Oyuki knows.

Slowly, carefully, Oyuki steps closer. ‘Atsu.’

No one says her name like that. Not as a legend, not as a warning, but as if it’s only hers.

‘I love you,’ Atsu breathes, because after all that, the truth is suddenly the easiest part.

Silence follows for a heartbeat. Not empty silence, not fearful, but the kind that forms when something long carried at last finds ground enough to be set down. Then Oyuki reaches up and touches Atsu’s face with such gentleness that Atsu’s breath catches. 

Her thumb rests briefly at the edge of her cheekbone, as if memorising the shape. ‘I know,’ Oyuki says, and her eyes shine with it. ‘I have for a while.’

Atsu gives a short, helpless laugh. ‘You might have warned me.’

Oyuki smiles. ‘I was waiting for you to catch up.’

It’s such an Oyuki answer that Atsu laughs again, softer this time, and some last, stubbornly hard thing in her chest loosens. When Oyuki dares to lean closer and kiss her a moment later, it doesn’t feel like a victory or a surrender. It’s quiet. Deliberate. Warm from the day’s fading heat and the nearness of shared breath. 

Atsu has known kisses before, in other lives, under other names and necessities, but never one that feels like this: not taking, not proving, not bargaining, simply staying. She puts a hand at the back of Oyuki’s neck and kisses her back with all the care she doesn’t know how to speak aloud. 

When they finally part, the sky has gone rose-gold over the hills, and neither of them says anything for a while; they just let their foreheads rest together and trade soft, shy smiles. Below them, far off, a wolf howls in the distance as if offering its approval to Atsu’s bravery. A river catches the last light, and the world, stubborn and ordinary, goes on. 

And Atsu thinks perhaps that is the miracle in and of itself. Not that the dead are avenged. Not that evil falls. Not even that she has survived enough to stand here now. But rather that after all of it, there’s still evening, still grass, still another person’s hand finding hers and remaining there.

She laces her fingers through Oyuki’s, and together they turn towards the home they’ve been tentatively making together.
