The return to normalcy at Seika High School after the cultural festival felt like waking from a fever dream, the corridors echoing with the subdued hum of post-celebration lethargy as students shuffled to their lockers, backpacks heavier with the weight of unread assignments and the faint, stubborn glitter that clung to everything like a refusal to let go. The quad outside, still bearing the faint scars of the festival—divots in the grass where booths had stood, a stray confetti fleck winking under the weak October sun—served as a silent reminder of the whirlwind that had swept through just days before. The air carried a crisp edge, laced with the musty scent of fallen leaves beginning to carpet the paths, and the distant ring of the first-period bell that pulled everyone toward the inevitable grind of midterms and club trials. For Kai Tanaka, the transition was a double-edged blade: the conspiracy's swan song—Mori's resonant confession via Dad's pocket watch, the empire's core cracked open in a carillon's peal—had handed the PD the final nails, arrests rippling through the alumni net like aftershocks. Mori in custody, Nakamura's circle crumbling under audit trails and forged inks dissolved, the hit-and-run's fog lifting to reveal justice's stark outline. But closure was a quiet thief; it stole the fire that had fueled his every step, leaving behind a hollow ache and the nagging whisper that shadows never truly settle—they just shift.
Kai adjusted his backpack strap as he navigated the hallway toward the club fair bulletin board, the cork surface plastered with flyers that fluttered like hopeful flags: Art Club: Ignite Your Canvas!, Lit Society: Words That Weave Worlds, Soccer Squad: Kick for Glory. The festival's unity had lingered in spirit, clubs buzzing with crossover energy from the banner collab and whisper chains, but the rosters for the new term were a battlefield of scratched names and hasty additions, freshmen hovering like wide-eyed recruits waiting for their moment. Haruka walked beside him, her school uniform crisp but for the glitter speck on her collar—a festival souvenir she wore like a badge—and a notebook tucked under her arm, filled with scribbled story prompts inspired by the echoed photos and resonant songs. She'd been his constant through the arc's crescendo—the veiled gala's unmaskings, the reconciliation circle's cathartic rings, the way Mori's swan confession had hung in the belfry's air like a noose finally severed. Now, in the corridor's fluorescent hum, she nudged his elbow, her smile a soft counter to the morning's gray.
"Club trials today—lit's got that 'shadow swap' icebreaker for newbies. Sound fun? Or are you still hearing echoes in your sleep?" Her tone was light, teasing the weight she knew he carried, but her eyes held that gentle probe, the one that invited without prying.
Kai managed a half-grin, pausing at the board to scan the rosters. "Echoes, yeah. Dad's watch chime—'Fight with ears open'—it's like he's narrating the quiet now. PD's tying the last knots: Mori's plea deal for the clause details, Ben Sr.'s full testimony on the wheel. Justice feels... settled. But the everyday? That's the real riddle." His finger traced the lit roster, names in neat columns: Haruka S., Yumi K., and a freshman's scrawl—Hiroki T.? Wait—Hiroki? The '87 overdose ghost from the negatives, but a namesake? No—typo? The entry blurred, swapped with another: Akemi L. (transfer alum?) Akemi—the witness? Roster glitch?
Sora barreled through the crowd then, his tie askew and backpack slung low, Yuki trailing like a devoted squire with a stack of soccer flyers. "Club chaos! Rosters swapped—freshmen freaking: 'I'm in debate, not drama!' Art's got a 'poet' signed as goalie, lit's debating kid listed for koto. Prank? Or glitch-fest?"
Yumi and Aiko caught up from a side hall, Yumi's ledger now a festival postmortem, Aiko's sketchpad bulging with post-event doodles. "Identity mix-up," Yumi said, peering at the board. "Not random—patterns: Freshmen swapped with alums' ghosts. Hiroki T.? '87 echo. Akemi L.? Witness nod. Mentorship swap from the chains—'shadows' trading places for trials."
Aiko nodded, flipping her pad to a quick roster web—lines crossing like tangled threads. "Light-hearted crisis: Newbies panicking IDs, but peels to forged friendships—festival's echo, alums 'swapping' in as mentors via roster hacks. Dad's era link? Old classmate?"
Kai's instincts stirred, the board's scrawls a new canvas. Emiko's silence post-confession felt like prelude: Swapped shadows? Let songs settle, or stir the swap? Back to school life, mini-mystery blooming from the arc's ashes—forged rosters as mentorship veil, tying to Dad's forgotten peer.
"Roster raid," Kai decided. "Club offices—trace the swaps."
The lit room was first, scripts strewn like fallen leaves, Haruka's desk piled with prompt cards. Roster book open: Freshman Mio K. swapped with Hiroshi T. (alum '22?)—Dad's name, ghosted. "Mentor echo," Haruka breathed. "Alums 'swapping' in—anonymous trials, guiding without glow."
Soccer office: Riku's clipboard showed Yuki S. (real) swapped with Riku H. ('92 alum)—Coach's era ghost. "Underdog chain," Sora said. "Festival's pay-forward—rosters rigged for shadow mentors."
Art nook: Aiko's ledger listed Lena M. swapped with Akemi L. (witness alum)—grieving net tie.
The web converged at the principal's annex—interim suit's desk, roster master file hacked subtle: Alum logins, festival app backdoor. Culprit? Mia from AV, grinning sheepish. "Swapped shadows—alumni game. Post-confession, we 'forge' friendships: Ghosts in rosters for trials, mentors veiled as peers. Dad's classmate? Me—his '22 trainee, swapped in for you. Surprise: Coffee chat, his old case tips."
Link: Mia, Dad's protégé—forgotten, now found. Mini-mystery: Light swaps to deep bonds.
Resolution: Trials 'unswapped' with reveals—freshmen beaming at mentors, friendships forged.
Haruka nudged Kai. "Shadows swapped—light."
Emiko: Settled songs. Next: 'missing' club key? Or let friendships chime?
Kai smiled. Everyday: Rosters not mixed, but matched.
