The morning sun filtered through the high windows of the student council room at Uranohoshi Girls' Academy, casting long, golden bars across the wooden table.
Usually, this room was a sanctuary of order and discipline, but today, the air was thick with a frantic, buzzing energy.
"He did what?!"
Chika Takami leaned so far over the table her nose nearly touched Dia's.
Her eyes were wide, sparkling with a mix of terror and genuine awe.
Beside her, You and Kanan exchanged worried glances, while Yohane struck a dramatic pose, muttering something about a "Guardian of the Abyss" intervening in mortal affairs.
Dia Kurosawa sat rigidly in her chair, her hands clasped tightly in her lap.
She had regained her composure—the "Perfect President" persona was firmly back in place—but the faint puffiness around her eyes betrayed the tears she had shed the previous evening.
"He caught the man's fist, Chika-san. Barehanded," Dia explained, her voice remarkably steady considering her heart hammered just thinking about it.
"It was... a display of efficiency I have rarely witnessed outside of professional martial arts."
Ruby, sitting close to Hanamaru, nodded vigorously, her pink twintails bouncing.
"It was like a movie! He was so tall, and his eyes were really scary, but then he asked if we were okay and his voice got all quiet."
"And you didn't get a name? Or a school?" Mari Ohara leaned in, a mischievous glint in her blonde eyes despite her obvious concern for her friends.
"A mysterious knight in shining armor appearing in the shopping district? That is so aesthetic!"
"Mari, it was a dangerous situation," Dia scolded, though there was no real bite in it. "He told us to be more careful in unpopulated areas and then simply... walked away. He didn't ask for thanks. He didn't even linger for praise."
"He sounds like a lone wolf," Riko mused, tapping her chin.
"But if he's our age and around Numazu, we're bound to see him eventually. For now, we have to focus. The performance at the Awashima Marine Park is today. We can't let yesterday's shock ruin our energy."
Dia took a deep breath, nodding slowly.
"You are right. We are Aqours. We perform to bring smiles to others. We cannot do that if we are wearing frowns ourselves."
Amanokawa Haruto wasn't trying to find her.
The world, however, seemed to have other plans.
He was walking along the coast near the Awashima Marine Park, the scent of salt and sun-warmed pavement filling his lungs.
It was a beautiful day, the kind that drew tourists out in droves, which was exactly why he was heading toward the docks.
He had a shift starting soon on a local fishing boat, helping his father's crew haul in the afternoon catch and prep the nets for the night run.
As he approached the plaza near the aquarium entrance, a familiar melody drifted through the air.
It wasn't the traditional opera he'd heard on the beach, but something upbeat, synthesized, and full of life.
He stopped.
A crowd had gathered around a makeshift stage decorated with blue and white ribbons.
There, standing in the center of the formation, were nine girls in shimmering sea-themed costumes.
And right in the side of the stage , her black hair whipping in the sea breeze as she moved with sharp, elegant precision, was the girl from the alley. Dia.
Haruto moved to the edge of the crowd, leaning against a railing. He intended to stay for only a moment, but the sheer energy of the group—Aqours, the banner behind them read—anchored him to the spot.
He also noticed someone very familiar.
"Isn't that Kanan, haven't seen her for a long time, So she knew that girl,".
They were singing about chasing dreams and the light of the ocean.
It was a stark contrast to the trembling girl he had seen yesterday.
Here, under the bright sun, she looked invincible.
Her movements were the most disciplined of the group, every gesture extended to its fullest, her expression a mask of professional joy that occasionally cracked into a genuine, radiant smile.
Beside her, the little sister with the twintails, Ruby, was dancing with a newfound confidence, her face bright with exertion.
Midway through their second song, the choreography required the girls to fan out across the stage, engaging with different sections of the audience.
Dia's eyes swept across the crowd, her "idol smile" practiced and bright.
But then, her gaze caught a shock of dark hair and a familiar, stoic face leaning against the railing at the very back of the plaza.
Her heart skipped a beat, nearly throwing her off-beat.
"It's him."
She didn't stop.
Her training wouldn't allow it.
But as she spun, her mind raced.
What is he doing here? Did he follow us? No, he looks like he's just passing through. Look at his clothes—he's dressed for work.
She looked at him again during a high note, and for a split second, their eyes locked.
She saw him nod—just a tiny, almost imperceptible movement of the head—as if acknowledging her strength.
Ruby spotted him a moment later.
She nearly tripped over her own feet, her mouth forming a tiny 'o' of surprise before she caught Dia's stern, warning glance.
Ruby quickly recovered, putting extra energy into her waves, her eyes sparkling. The hero came to watch! she thought excitedly.
The rest of the girls noticed the shift in the sisters.
Chika, always perceptive, followed Dia's line of sight and saw the boy. He stood out like a shadow in the sun—quiet, observant, and completely disconnected from the cheering fans around him.
"Is that him?" Chika wondered, her smile widening. " He looks so cool!"
For the duration of the final chorus, the stage felt different.
For Dia, it was no longer just a performance for the tourists; it was a demonstration.
She wanted to show him that she wasn't just the girl who cried in an alley.
She was a leader. She was a performer. She was strong.
As the final note faded and the girls struck their ending pose, breathing heavily and soaked in sweat, the crowd erupted into applause.
"Thank you so much!" Chika shouted into the microphone, waving frantically.
"We are Aqours! Please enjoy the rest of your day at the aquarium!"
The girls bowed in unison. Dia stayed down a second longer than the others, her eyes fixed on the spot by the railing.
By the time she straightened up, the spot was empty.
The boy was gone. There was no sign of him in the dispersing crowd.
It was as if he had been a ghost conjured by the salt spray.
"He's gone," Dia whispered, a strange pang of disappointment echoing in her chest.
"Don't worry, Dia-chan!" Mari popped up behind her, slinging an arm over her shoulder. "He probably had to go save another princess in distress."
"He didn't look like he was looking for trouble," Kanan said, looking toward the docks. "He looked like he was heading toward the harbor. Probably a local worker ,he looks somewhat familiar," holding her hands on her chin,.
"I wanted to thank him properly," Ruby pouted, her shoulders sagging.
"We didn't even get to tell him our names."
Dia looked out toward the shimmering blue of the bay.
Far off in the distance, she could see the silhouette of a fishing vessel pulling away from the pier, its engine a low hum against the sound of the waves.
"We will see him again," Dia said, more to herself than to her sister.
She adjusted the ribbon on her costume, her eyes regaining their sharp focus.
"Someone like that doesn't just appear twice by accident. Next time, I won't let him walk away without an introduction."
Haruto stepped onto the deck of the Kuroshio-Maru, the familiar scent of diesel and fish scales grounding him.
He ignored the curious looks from the older fishermen as he began to haul a heavy crate of ice toward the storage hold.
"You're late, Haruto!" His father barked, though there was a grin on his weathered face.
"Stop to watch the idols, did you?"
Haruto didn't look up, his muscles tensing as he lifted the crate.
"I was just passing by."
"They're good kids, those girls," the captain said, lighting a cigarette.
"Trying to save the school, they say. Takes a lot of guts to stand up there in front of everyone."
Haruto paused for a moment, the image of the black-haired girl—Dia—singing her heart out flashing through his mind.
She hadn't looked like a victim today. She looked like a leader.
"Yeah," Haruto muttered, his voice barely audible over the cranking of the boat's winch. "I guess it does."
He turned back to his work, the rhythm of the sea taking over, but for the first time in a long while, the quiet of his life felt a little less lonely.
