In the isolated coastal town of Kurohane, eerie spiral patterns begin appearing everywhere—on walls, in trees, even in people’s reflections. When Renji Kisaragi, a skeptical high school journalist, returns home after hearing about his brother Shun’s sudden and mysterious death, he finds himself trapped in a nightmarish time loop.

Every time he dies, time rewinds—resetting two days earlier. But with each reset, reality twists further: people disappear, time fractures, and his own body begins to change. As he searches for the cause, he discovers his estranged father, Kaoru Kisaragi, may have been the one who triggered the loop.

Aided by his childhood friend Aoi Tsukimura, who holds secrets of her own, Renji must uncover the mystery of The Spiral Gate before it consumes everything. But some truths are worse than death. And the entity behind the spirals does not want to be stopped.

Renji must make an impossible choice: sacrifice himself to break the loop—or risk losing his humanity to escape.

The sea was unnaturally calm as Kuro's fragmented reflection shimmered beneath the moonlight. Renji stood frozen, the words still echoing in his ears: "The Mirror Spiral."


Kuro knelt and traced a spiral into the wet sand. But this spiral didn't curl inward. It curled outward—like a blossom, not a trap.


> "The Spiral we knew twisted memory, time, and self inward. It consumed," Kuro said quietly.


"But the Mirror Spiral… it reflects everything you don't want to face. Your truth. Your lies. Your hidden selves."


Renji frowned. "So what—some kind of spiritual mirror?"


Kuro's eyes gleamed. "No. A world. A living world. Inverted."


The following day, Renji walked the town, trying to ignore the chill in his spine.


People were starting to remember things they shouldn't.


Old classmates who'd disappeared during the Spiral events were suddenly back—but not quite right. They moved with mechanical precision. Their smiles were hollow.


In the local market, an elderly woman looked up from her stand and said, "You've changed, Renji-kun. Or maybe… I've seen the other you."


The spiral was supposed to be gone. But the cracks had only deepened.


That night, Renji woke to find another version of himself standing in the mirror.


His copy smiled. Not cruelly. Almost… sadly.


> "I'm the you that never cut the Spiral," it whispered.


Renji returned to the shore the next night. Kuro was waiting.


The waves moved backward. The moonlight reflected a second shoreline—in the water—but everything was reversed. Trees grew upside down. Stars formed spirals.


Renji's Spiral Blade, now dull and locked, began to hum.


Kuro nodded solemnly. "That's it. The Mirror Spiral's threshold. You're the only one who can enter now."


Kuro smiled faintly. "Because you carry the memory of every version of yourself. Only the truth-breaker can survive in the world of reflections."


Renji turned once to look back at the town—at the life he'd finally reclaimed.


And Renji was pulled into the Mirror Spiral.
