The Mirror and the Moth: The Hashira’s Heirloom (Arc Synopsis)
Would you keep a secret if you knew it might hurt someone close to you? Hajime Rakka doesn’t want to set his friends at risk. But a strange mirror deep in the school warehouse forces his hand.
Hajime’s suited best to chess and old book clubs. People forget he’s there. He blends in after the summer he’d rather not talk about, the one where he lost his grandpa. So when student council leader Makoto offers an invite to join the after-school Paranormal Pursuit club, he shrugs and agrees. It’s just Makoto, Asahi Natsume (class clown and manga nut), and Rui, the shy computer whiz—none seem much like trouble.
They pick out a backroom for their first meeting. Dust, locked cabinets, moldy boxes—the usual stuff. But wedged behind a sagging shelf is a hand mirror with a silver moth etched on its handle. Hajime pries it out. A cold tremor runs through him. He’s not the only one. Their hands burn with the cold, and the glass fogs with their breaths. Makoto points out the kanji inked inside the rim. Is this luck, fate, or both working against them?
Later, at home, Hajime notes odd dreams. Cold light, thin fluttering wings, and an old man trapped in a wooden temple. Ruins, faces he never met, then his grandpa—insomniac, sleepless, crying at midnight. These aren’t his memories. Or are they? Do objects remember things too?
The next meeting, odd things pop up. Rui can’t log in to the school server. Asahi sees new bruises on his arm that sting beneath warm water. Makoto can’t recall the code to his own bike lock. The group blames tests, stress, and ignores glitches. But that mirror now shifts when no one’s looking. Its moth emblem, once dull, gleams like real silver on some nights.
Rui tries to hack the library for folklore about school relics. She digs up an old scan. The ‘Hashira Mirror’ appears in a yellowed club diary—banned after granting wishes but always asking a price. If you see a moth in your reflection, your memory gets borrowed for a spell. Do they even know what each other looks like anymore?
Tension bubbles over. During a fierce rain, Makoto stays late to study (he forgot the law textbook he always carries). Out of habit, he glances at the strange mirror, now left by the clubroom door. The moth isn’t in his reflection—but another face is, older, snarling, then pleading in silence. Lightning drives him backward and he calls Hajime in terror. “It’s eating something. I think it’s memories!”
By the week’s end, Hajime can’t recall his chess strategy. Asahi loses his manga spark. Rui struggles with her own phone lock. The curtain falls hard when, at midnight Friday, all four wake in pools of sweat, in places they don’t remember going to bed. Hajime clutches the mirror—he swears he glimpsed his grandfather again, begging not to be forgotten. What is real, and what do cursed things count as truth?
They vow to return the mirror. But when they try, the clubroom is gone, swallowed by blank, windowless corridors that don’t line up on the school floor map. There’s a sound, like hundreds of moths tapping at glass, echoing into the unknown. Hajime leads them towards the sound; they press on, hoping they haven’t lost themselves for good. The last scene: all four see their reflections shifting—faces young, old, lost and pleading—across endless silver.
What if the only way out is letting the mirror have something they can’t get back? Who chooses what we forget—and who we keep alive outside our memories?
To be continued.
