For a girl who'd died dozens of times, Aira Nishimura was awfully good at pretending everything was normal.
The next morning, she greeted Yuto with her usual smile—bright, teasing, and way too energetic for 7:30 AM. She tossed him a canned coffee as if they were two carefree teenagers, not time-looping anomalies tangled in cosmic deja vu.
But Yuto saw it now—the slight tremble in her hands, the way her eyes lingered on things a second too long. She remembered more than she let on.
And he was finally ready to ask.
"Aira," he said as they walked to school, "how long have you really been looping?"
She didn't look surprised. She just sighed and took a long sip of her drink.
"Longer than I wanted. Not as long as I needed."

Flashback: The Rooftop, One Loop Ago
Aira stood under a bruised-purple sky, clutching a charm necklace. A storm raged in the distance, thunder growling like a living beast.
Beside her, a girl—Kana—held out her hand.
"You don't have to do this alone, Aira."
But Aira shook her head, tears streaking down her cheeks. "If I break the loop, I disappear. That's the trade."
And then the lightning struck—

Present
In the classroom, the day was business as usual. Or as "usual" as it got when you had two loopers, a sidekick who talked to microwaves, and a student council president (Yuki) who may or may not be running a secret organization.
Yuto and Aira sat side by side, pretending to take notes during math.
"Ever feel like we're the only sane ones left?" Aira whispered.
Yuto raised an eyebrow. "You're saying you're sane?"
"Relatively," she said, grinning.
Behind them, Hiro and Kana were passing notes—actual paper notes like it was 2004. Kana's note read:
"Yuto glowed slightly when the bell rang. Scientific anomaly or caffeine overdose?"

Lunchtime came—and Aira vanished.
Yuto found her exactly where he expected: the abandoned music room.
She was seated at the piano, not playing, just resting her fingers on the keys like they were bones of something long dead.
"You followed me," she said softly, not turning around.
"I would've followed you through a hundred timelines," Yuto replied.
She finally looked back at him. Her smile was cracked glass.
"You really want the truth?"
He nodded.
"I'm not supposed to be here," she said. "Not in this loop. Not in any loop."

She told him everything.
How she'd died in Loop Zero—before the system ever activated. How a fragment of her memory clung to the loop. How she rebuilt herself—faint echoes at first, then full awakenings. How she started remembering him.
"How did you keep it together?" he asked, shaken.
"I didn't," she said. "I broke. Over and over. But I kept smiling, because that's what you remembered about me."
Yuto stared at her. "You remembered me before I remembered you."
"Every time," she whispered. "Every time, I found you again."
He reached out, fingers brushing hers. "Then this time, let me remember you. All of you."

They walked home that evening beneath blooming sakura trees, the petals falling like soft snow.
Yuto asked one last question. "If you're not part of the system, how are you still here?"
Aira looked up at the sky.
"I think… someone left a door open. And I slipped through."

Elsewhere…
A masked figure stood in the school's science lab, examining a burning pocket watch.
"She's waking up," he murmured. "And so is he."
He dropped the watch.
It stopped midair.
Time bent around him.
"Soon, we'll see who really belongs in this loop."
