The cultural festival at Seika High School transformed the sprawling campus into a labyrinth of light and laughter, a riotous tapestry of booths and banners that seemed to pulse with the collective heartbeat of its students. Strings of paper lanterns swayed gently from the eaves of every building, their rice-paper globes painted with whimsical motifs—dragons chasing fireflies, cherry blossoms caught mid-dance—that glowed warm against the deepening twilight. The air was thick with the sizzle of takoyaki from the food stalls, the twang of koto strings from the music nook, and the undercurrent of excited chatter as families and alumni wandered the paths, red festival stamps dotting their hands like badges of belonging. It was Seika's annual exhale, a celebration that had taken on deeper meaning this year: after the Mori scandal's long shadow, the festival wasn't just fun; it was defiance, a declaration that the school rose brighter from its ashes.
Kai Tanaka navigated the throng with his usual measured stride, a paper lantern dangling from his wrist like a talisman, its soft orange light casting flickering patterns on his sneakers. He'd volunteered for "lantern patrol" as a low-key way to keep an eye on the grounds—Sora's idea, half-joke about "detective under lights"—but really, it was a chance to breathe amid the chaos. Haruka walked beside him, their arms brushing occasionally in that new, tentative rhythm they'd found since the banner reveal, her lit club badge glinting under the lanterns. She clutched a stack of "Phoenix Tales" bookmarks, handing them out with shy smiles, her glasses fogging slightly from the steam rising from a nearby yakisoba stand.
"This is magic," she said, pausing to adjust a lantern that had tangled in a low branch. The paper globe spun lazily, revealing hand-painted kanji inside: Light the path. "After everything—the gala bust, the whispers—seeing everyone weave it together? Feels like the phoenix isn't just art anymore."
Kai nodded, his gaze drifting over the crowd. Sora was manning the soccer booth, dramatically reenacting the trophy "heist" with exaggerated dives that drew cheers from clusters of underclassmen. Aiko darted between the art display and the food line, her neon-edged phoenix banner now the archway's crown jewel, glowing under UV strings like a beacon. Yumi coordinated the lit nook, her voice carrying snippets of story prompts that pulled passersby into impromptu readings. It was unity in motion, the larger tapestry Emiko had hinted at unfolding in real time. But beneath the glow, Kai's detective instincts hummed—a faint dissonance, like a note slightly off-key in the festival's symphony.
It started with a first-year's yelp from the lantern path near the old wing. "It's... talking!" The kid, a wide-eyed girl with pigtails and a festival yukata too big for her frame, pointed at a lantern dangling from a low-hanging wire. The globe flickered erratically, its light pulsing like a heartbeat, and through the semi-translucent paper, shadowy kanji danced inside—projected? Etched? You are seen. Keep chasing the stars. The message faded as quickly as it appeared, leaving the lantern swinging innocently, but the girl's eyes were round as mochi. "Cursed! It knows me—I told my friend last week I want to be an astronomer!"
Word spread like wildfire through dry grass. By the time Kai and Haruka reached the cluster, a small crowd had gathered: freshmen whispering, upperclassmen snapping photos for the school LINE. Another lantern nearby flickered—Your sketches light the dark. Don't stop drawing. A boy in art club colors gasped, clutching his sketchpad. "That's my journal doodle—from Tuesday!"
"Cursed lanterns," Sora panted, jogging up with a half-eaten skewer in hand. "Half the path's doing it. Eerie messages, personal as a diary leak. Freshmen think it's Mori's ghost—payback prank. But look—" He held up his phone, a blurry video of a globe pulsing: Kick harder. The goal's yours. Riku's mantra, from practice chats.
Yumi materialized from the shadows, Aiko in tow, both with that shared "mystery mode" glint. "Not curse—code," Yumi said, examining a flickering lantern up close. The light inside wasn't flame; it was LED, battery-powered, with thin paper scrolls curled like mini-projections. Unroll one carefully: handwritten kanji on rice paper, backlit to glow through the globe. Your voice carries. Sing louder. Addressed to a shy music club first-year who'd confided stage fright to... whom?
Aiko unrolled another: The equations bend for you. Tutor's waiting. To a math-phobic freshman, echoing Tsubasa's old swap plea. "Well-wishes. Anonymous cheers. But how? Who's the network?"
Kai's mind raced, details slotting. The lanterns: standard festival stock, hung by volunteer teams—clubs mixed, freshmen heavy on grunt work. Scrolls: thin washi paper, ink fresh but feathered like hurried fountain pens. Placement: clustered near underclass booths, paths freshmen frequented. Not haunt—heart. Emiko's nod: Freshmen shadows. Dad's legacy? Hiroshi Tanaka, the detective who'd mentored rookies with quiet notes in case files: See the person behind the puzzle.
"Hidden mentorship," Kai murmured, the pieces crystallizing. "Upperclassmen—us, post-scandal survivors—slipping encouragements. Pay-it-forward chain. Dad did it: anonymous tips to new cops, 'keep digging, kid.' Echo here."
Haruka's eyes widened, touching a globe gently. "That's... beautiful. But the flicker? Battery glitch, or dramatic flair?"
Sora tested one—steady glow till he jostled it, then stutter: LED loose wire? "Flair fail. But messages—personal. Who scouted?"
The crowd thinned as announcements blared: Booth rotations! Kai led the group to the volunteer tent, lanterns swaying overhead like conspiratorial stars. Sign-up sheets: freshmen names thick, paired with upper mentors—Riku with a soccer newbie, Aiko's art leads shadowing sketch circles. But the real web? A hidden roster, tucked in a locked cubby: Mentor Chain—Seika Sparks Initiative. Started post-gala, anonymous drops in lockers, evolving to lantern whispers.
Yumi jimmied the lock—hairpin pro. Inside: scroll master list, penned by... Emiko? No—collective, initials scattered: S for Sora (his goal note?), A for Aiko (drawing cheer). And H.T.—Hiroshi Tanaka? No—handwriting match: Dad's old case notes, copied? Kai's throat tightened. A freshman coordinator, inspired by trial tales, had photocopied public files—Dad's "mentorship memos," anonymized encouragements to witnesses: Your truth lights the way.
"Legacy lantern," Haruka whispered, squeezing Kai's hand. "He'd love this."
Resolution warmed: No curse—candle. They rallied the chain: freshmen awed, upperclassmen sheepish but beaming. Fix the flickers—Sora's wiring hacks, Aiko's glow paint. Unveil at closing: Lantern path as "Whisper Walk," messages read aloud, cheers cascading. Principal choked up: "Shadows to sparks—Hiroshi's spirit."
Under the arch, Haruka leaned in. "Your dad's weave—endless."
Emiko's text: Lit. Next: 'lost' festival prize? Or let whispers warm?
Kai smiled, lanterns aglow. Everyday: lights not cursed, but kindled.
