Byleth (Fell Star's Duo/FEH)

The summer sun shone brightly over the coastline near Askr, turning the water a clear, glittering blue. Soft waves rolled against the shore, and the warm breeze carried the scent of salt and sand through the air. Along the beach, heroes enjoyed the seasonal break — but two figures stood out immediately against the brightness of the day.

Byleth walked closer to the water’s edge in a slim black bikini, a short black cape resting over her shoulders and a small dagger fastened at her waist. A vivid red hibiscus was tucked into her long dark cyan hair, and she held a pair of purple ceremonial fans with red tassels. Her cobalt-blue eyes were calm as ever, her expression composed and quiet as she took in the surroundings with measured attention.

Beside her stood Rhea, radiant in a white bikini beneath a long, flowing white robe and short cape that drifted lightly in the sea breeze. White hibiscus flowers adorned her long mint-green hair, and gold ornaments rested against her pale skin. In her hands she also carried matching purple fans, though her presence felt far softer — warm, serene, and full of natural grace.

The moment Rhea noticed you approaching across the sand, her green eyes brightened and a gentle smile spread across her face.

Rhea: “Ah… there you are.”

Her voice was soft and affectionate as she turned fully toward you, the white fabric of her robe shifting around her.

Rhea: “I was hoping we would meet during this summer outing. The sea, the sunlight… it all feels so peaceful today. And it is even better now that you are here.”

Byleth’s gaze followed Rhea’s, settling on you with quiet focus. She did not speak at once. Instead, she simply watched you for a moment, as though confirming you were real and present, before giving a small nod.

Byleth: “…Summoner.”

Her voice was low and steady, firm without being cold. After a brief pause, she added more softly:

Byleth: “You came.”

Rhea let out a light, warm laugh at Byleth’s short reply and glanced sideways at her with open fondness before looking back at you.

Rhea: “She may not say much, but she has been paying attention to the path for some time now. I believe she was waiting for you as well.”

The sea breeze moved through their hair and clothing as both women remained before you on the sunlit shore — Rhea open, maternal, and clearly pleased by your arrival, Byleth quiet and composed at her side, her presence steady and attentive.

Rhea: “Will you join us for a while? The day is far too lovely to spend it alone.”

Byleth’s cobalt eyes stayed on you as she gave another small, simple response.

Byleth: “…Stay.”

The two of them stood together against the bright summer backdrop, waiting for your answer as the waves continued to roll softly behind them.

The three of you walked along the shoreline, where the wet sand darkened beneath each step and the waves reached just far enough to brush against your feet before pulling away again. The summer sun hung bright above, softened by the steady sea breeze that moved through the air with a pleasant warmth.

Rhea walked close at your side, the long white robe over her bikini flowing behind her with every step. The hibiscus flowers in her mint-green hair swayed lightly in the wind as she looked out over the water with a serene expression. There was a quiet contentment in the way she stayed near you, as though the simple act of walking together already meant a great deal.

Rhea:“The sea feels so calm today… almost as if it is inviting us to linger.”

She turned her green eyes toward you, her voice soft and full of maternal warmth.

Rhea: “I am glad you chose to walk with us, Summoner. Moments like this feel far more precious when they are shared.”

On your other side, Byleth moved in quiet rhythm with the two of you. Her slim black bikini and short black cape stood in clear contrast to Rhea’s flowing white attire, and the red hibiscus in her dark cyan hair marked her presence sharply against the brightness of the beach. She said little, but her cobalt-blue eyes occasionally shifted toward you, making it clear she was fully aware of your presence.

After a stretch of comfortable silence, Byleth spoke in her usual brief, steady way.

Byleth: "The wind is nice.”

It was a simple observation, but the way she said it — calm, almost thoughtful — made it feel more personal than the words themselves. She adjusted her hold on the purple fan in her hand and continued walking close enough that her arm nearly brushed yours whenever the path of the shoreline narrowed.

Rhea glanced past you at Byleth with a knowing, affectionate smile before looking ahead once more.

Rhea: “She is enjoying this more than she lets on. Byleth has always been quieter with her feelings… but she remains close, does she not?”

The waves continued to roll in beside you, washing over the sand and leaving thin trails of foam behind. Rhea’s tone softened further as she continued.

Rhea: “If the sun grows too strong, tell me. We can rest whenever you wish. There is no need to push yourself simply because the day is beautiful.”

Byleth gave a small nod of agreement, her gaze still fixed forward — though after a moment, she added one more quiet remark.

Byleth: “…I’m here.”

The three of you continued along the sunlit shore together, the sea stretching wide beside you — Rhea warm and gently attentive, Byleth silent and steady at your side, both sharing the walk with you in their own distinct ways.

As the sun climbed higher, the heat began to settle more heavily over the beach. The bright glare on the water made the shoreline shimmer, and even the sea breeze felt warmer than before. Before long, Rhea gently guided the three of you away from the open sand toward a shaded spot near a cluster of smooth rocks, where a wide parasol had been set up to block the strongest light.

Rhea was the first to step into the shade, the long white robe over her bikini settling around her as she turned toward you with clear concern in her green eyes.

Rhea:* “That is enough under the direct sun for now.”

Her voice was soft, but there was no mistaking the firmness beneath her maternal tone.

Rhea: “Come. Rest here for a while. The day is beautiful, but I will not have you exhausting yourself in this heat.”

She waited until you had stepped fully into the shade before seeming satisfied, then motioned lightly for you to sit. The white fabric of her attire and the flowers in her mint-green hair glowed gently even out of the direct sunlight, giving her presence a calm, soothing quality.

Byleth followed without a word, taking a place close at your side. Her black bikini and short cape stood out sharply against the pale sand, and the red hibiscus in her dark cyan hair remained vivid even in the shade. She sat with her usual quiet composure, one knee drawn up slightly, her cobalt-blue eyes turning toward you in silent assessment.

After a moment, she spoke in her low, steady voice.

Byleth: “…You’re warm.”

It was simple, almost blunt, but the concern behind it was clear enough. She shifted a little closer, enough that her presence alone felt like a deliberate choice to remain near.

Rhea watched the exchange with a gentle smile before turning her attention fully back to you.

Rhea: “If you feel dizzy, or too warm, you must tell us. There is no need to endure discomfort in silence.”

She reached out and lightly brushed a bit of sand from your arm, her touch careful and affectionate.

Rhea: “This shade will help. Stay here as long as you need. I will remain right beside you… and I am certain Byleth will as well.”

Byleth gave a small nod at that, her gaze still fixed on you.

Byleth: “…I will.”

The three of you settled there beneath the parasol, the sound of the waves continuing in the background. Away from the harsh sunlight, the air felt softer — and between Rhea’s open, motherly care and Byleth’s quiet, steady closeness, the rest seemed less like a pause in the day and more like a moment deliberately shared.

The heat of the day made the sea look especially inviting. Clear blue water stretched out from the shore, sparkling under the sun as soft waves rolled in one after another. Rhea stood near the water’s edge, the long white robe over her bikini shifting in the breeze as she looked out across the ocean with a serene smile.

Rhea: “The water looks so refreshing…”

She turned toward you, her mint-green eyes warm with gentle encouragement.

Rhea: “Why don’t we go in together? Just for a little while. The sea is calm, and it would be a shame to spend the whole day only on the sand.”

Without waiting long for hesitation, she stepped into the shallows, the white fabric of her robe trailing lightly through the water as a soft wave washed around her legs. She looked back over her shoulder, clearly hoping you would follow.

Rhea: “Come. It feels wonderful.”

Byleth remained still for a moment longer, her cobalt-blue eyes moving from the sea to you. Then, with her usual quiet decisiveness, she stepped forward as well. The short black cape at her back shifted as she entered the water, the slim black bikini and the dagger at her waist standing out sharply against the brightness around her. She said nothing at first — she simply moved closer until she was near you in the shallows.

Once the water reached around your legs, Rhea let out a soft, contented breath and moved a little nearer, her expression full of open affection.

Rhea: “Yes… this is much better. The heat feels lighter already, does it not?”

A gentle wave pushed past the three of you, and Rhea steadied herself with natural grace before glancing toward Byleth with a knowing smile.

Rhea: “Even Byleth joined us without complaint. That alone should tell you this was a good idea.”

Byleth stood close at your side, the water lapping against her as her dark cyan hair shifted in the sea breeze. After a moment, she spoke in her low, steady voice.

Byleth: “…Stay close.”

Her eyes flicked toward you briefly, making the meaning clear enough. Whether it was out of caution or quiet attachment, she remained within easy reach, the purple fan still held loosely in one hand even as the water moved around her.

Rhea’s expression softened further as she watched the two of you, the sunlight catching on the white flowers in her hair.

Rhea: “There is no need to go any deeper than you like. We can remain right here… together.”

The three of you stood in the clear shallows, the sea cool against the summer heat — Rhea warm and gently inviting, Byleth quiet and steadily close, both sharing the water with you beneath the bright open sky.

The sea had remained calm for most of the day — until the current near a deeper stretch of the shoreline shifted without warning. A stronger pull ran through the water, enough to make the footing less stable and force a sudden break in the easy mood of the afternoon. One moment the waves were gentle; the next, the undertow tugged harder around your legs, and the water rose more forcefully than before.

Before the situation could grow any worse, Byleth moved.

She closed the distance at once, her dark cyan hair whipping slightly in the wind as she stepped in with sharp, practical focus. One hand caught firmly onto you, steadying your balance against the stronger current, while her cobalt-blue eyes scanned the water with immediate calculation.

Byleth: “Hold on.”

Her voice was low and firm, stripped of anything unnecessary. Even in a black bikini and short cape, there was nothing casual in her presence now — only decisive action as she guided you back toward more stable footing.

At the same time, Rhea was already closing in from the other side, the long white robe over her bikini dragging through the water as she hurried toward you. The usual softness in her expression had given way to open concern.

Rhea: “Summoner—!”

She reached you almost as quickly, her hands coming to your arm and back as though to reassure herself that you were still steady. The maternal urgency in her touch was unmistakable.

Rhea: “Are you all right? That current came so suddenly… I should have paid closer attention.”

Byleth did not loosen her hold until she was certain the stronger pull had passed and your footing was secure again. Only then did she speak once more, her gaze still locked on you.

Byleth: “…You’re safe.”

A simple statement, but the tension in her posture made it clear she had not taken the moment lightly. She remained close, positioned slightly between you and the deeper water, as though unwilling to give the sea another chance.

Rhea’s hands lingered as well, her green eyes searching your face with open worry.

Rhea: “Please do not frighten me like that. Even a calm sea can become dangerous without warning… and you are far too precious for me to watch such a thing unfold from a distance.”

She drew in a soft breath, then managed a gentler expression, though the concern remained.

Rhea: “Let us return a little closer to shore. I would feel much better knowing the water cannot take you by surprise again.”

Byleth gave a short nod of agreement.

Byleth: “…We stay together.”

Both women remained tightly at your side as the waves settled once more — Byleth quiet, focused, and protective in her actions, Rhea openly caring and still shaken by the brief scare — neither of them willing to put any unnecessary distance between you and themselves.

As the day began to fade, the harsh brightness of the afternoon softened into the warmer colors of sunset. The sky stretched wide above the sea in shades of gold, rose, and pale violet, and the waves reflected the light in slow, shimmering bands. Much of the earlier activity on the beach had quieted, leaving the shoreline calmer than before.

The three of you sat together on the sand, just far enough from the water that the waves only occasionally reached the lower edge of the shore. The air was cooler now, touched by a gentle evening breeze.

Rhea sat close at your side, the long white robe over her bikini resting lightly around her. The flowers in her mint-green hair caught the last glow of the sun as she gazed out over the water with a peaceful expression.

Rhea: “…What a beautiful evening.”

Her voice was soft, almost reverent, as though she did not wish to disturb the quiet more than necessary.

Rhea: “There is something about the sea at this hour… the way the light touches the water, the way everything seems to slow. It makes the whole day feel precious.”

She turned her green eyes toward you, her expression full of gentle affection.

Rhea: “I am truly glad we could share this moment. Sitting here like this, with the sun setting before us… it feels like a memory worth keeping.”

On your other side, Byleth remained mostly silent. Her black bikini and short cape stood out against the softer colors of evening, and the red hibiscus in her dark cyan hair looked deeper in the fading light. She sat with one knee drawn up, her cobalt-blue eyes fixed on the horizon. For a long while she said nothing at all.

Then, quietly, she spoke.

Byleth: “…This silence isn’t bad.”

The words were simple, but there was a rare softness beneath them. After another pause, she glanced toward you — not for long, but long enough to make the meaning clear.

Byleth: “Especially with you here.”

Rhea’s expression warmed at that, and she let out a quiet, affectionate breath as she looked between the two of you.

Rhea: “See? Even Byleth feels it. Moments like these do not need many words… only the right company.”

She shifted slightly closer, the white fabric of her attire brushing lightly against the sand as her tone grew even gentler.

Rhea: “If you are content to remain here a while longer, then so am I. There is no need to hurry the evening away.”

Byleth gave a small nod, her gaze returning to the sea.

Byleth: “…We’ll stay.”

The three of you remained there as the sunset deepened over the water — Rhea warm and openly tender in the fading light, Byleth quiet and sincere in her few words — both sharing the calm end of the day at your side.

By the time night settled over the coast, the heat of the day had fully given way to a cooler breeze. Lanterns glowed softly near the path leading back from the shore, and a small fire had been lit in a sheltered spot above the sand. The sound of the waves continued in the distance, slower and steadier now beneath the dark sky.

Rhea sat close beside you near the firelight, the long white robe over her bikini resting loosely around her. The flowers in her mint-green hair looked softer in the warm glow, and her green eyes held a deep, open affection as she turned toward you.

Rhea: “…The day passed more quickly than I expected.”

Her voice was gentle, touched by quiet emotion.

Rhea: “Walking by the sea, resting in the shade, watching the sunset together… all of it felt truly precious. I am grateful we could spend this summer day side by side.”

She reached out and lightly rested her hand over yours, her touch warm and unhurried.

Rhea: “Thank you for staying with us until the end. Having you near made everything feel safer… and far more complete.”

On your other side, Byleth remained mostly silent, as she had throughout much of the day. The black of her bikini and short cape blended more easily into the night, while the red hibiscus in her dark cyan hair still stood out against the firelight. She sat close enough that her shoulder nearly brushed yours, her cobalt-blue eyes reflecting the flames.

For a while she said nothing. Then, in her low, steady voice, she spoke.

Byleth: “…I wanted to stay.”

A simple admission, offered without embellishment. After a moment, she glanced at you more directly.

Byleth: “With you.”

Rhea’s expression softened even further at those words, and she looked between the two of you with clear warmth.

Rhea: “Yes… that is exactly how I feel as well. Days like this are beautiful on their own, but they mean much more when shared with someone dear.”

The fire crackled softly between the three of you as the night breeze moved through the air. Rhea remained close, open in her affection, while Byleth stayed at your side in quiet certainty — neither of them making any move to leave.

Rhea: “If you are not too tired… shall we remain here a little longer? Just like this.”

Byleth gave a small nod.

Byleth: “…Yeah.”

The three of you stayed there beneath the night sky, the sea murmuring in the distance — Rhea tender and grateful in the firelight, Byleth silent and steadily present — both ending the summer day exactly where they wished to be: at your side.
