Kentarō, an ordinary university student scraping by with part-time jobs, meets a strange yet enchanting girl named Sarah who claims she’s from “Heaven.” What begins as a quirky fruit stall argument turns into a life-altering journey across timelines.
Sarah isn’t human—not entirely. She’s a time-bound existence, appearing across world lines to save Kentarō again and again from tragic ends. But no matter how many times they restart, one of them always dies.
Bound by emotion and timelines, Kentarō fights to break the loop. Through magical relics, strange visions, and battles with a shadowy time assassin, the two challenge fate itself to carve out one world—just one—where they both live and love freely.

Kentarō woke up alone.That wasn't new.


But what was?The emptiness.His phone had no messages.His wallpaper had changed.The sketch Reika gave him—the one of him and Sarah on the rooftop—now showed only him.Smiling at no one.


He said the name aloud—once, twice—


He stormed into the university records office.


Her dorm room was locked—and erased from the housing registry.


Kentarō sat on the bench outside her building.


A tear fell.It hit the ground.But it didn't make a sound.


As if reality itself refused to acknowledge his grief.


He went to Reika.Held her sketchbook up.


"I don't remember drawing… anyone there."


"You've been talking to yourself lately."


He walked away in silence.She watched him go, frowning, disturbed—but no name came to her lips.


Back at home, Kentarō sat at his desk.


His hands trembled as he took out the cracked memory crystal—the one Sarah gave him back in Volume 2.


It pulsed faintly.Flickered.Then played one last recording:


"Kentarō... if you're hearing this, I'm gone.But this isn't another death.This is... the world forgetting I ever was."


"You might be the only one who remembers.So please—don't waste that gift."


"Write me a world where I still belong."


"Even if no one else believes it… you will."


He opened his journal.Wrote on the first blank page:


"Sarah-chan.The girl who came from nowhere.Who argued over apple prices.Who once placed her forehead against mine to learn the world."


"The one who smiled at broken stars, and fought Chronos with a blade made of memories."


The more he wrote, the more his room changed.


A photograph blinked into existence on his desk—faded, but two shadows stood side by side.


🕊️ Final Scene – A Voice in the Wind


Outside, the wind blew across the rooftop.


A paper with Kentarō's writing on it fluttered, then lifted into the sky.


He looked up at the moon.And smiled through his tears.
