The name hit Akira like a cold wave of recognition.
Saeko Busujima.
In the countless novels and manga he'd consumed in his previous life, that name was synonymous with one thing: the Highschool of the Dead. If she existed here, then the world-altering zombie outbreak—the Influenza-coded plague that turned humanity into shambling predators—was a statistical inevitability.
His mind raced, calculating threats and probabilities. In a universe already saturated with Monsters, Devils, and Cursed Spirits, a zombie apocalypse seemed almost quaint. The Hero Association alone could probably contain a biological outbreak before it spread beyond a single city block. But "probably" was not "certainly." The Zombie Devil—if such a being existed here—could weaponize the virus in ways the original narrative never imagined.
Better safe than sorry. The axiom crystallized in his mind. He would need to be vigilant. Stockpile supplies. Identify allies. And perhaps most importantly, position himself close to those with high survival potential.
He opened his mouth to initiate contact with the kendo prodigy seated before him. "Hello, classmate—"
Ding-dong-ding-dong~
The class bell cut him off with merciless precision.
A woman in a perfectly pressed formal suit strode to the podium with the crisp, measured steps of someone who had rehearsed this entrance. Her long pink hair was styled with meticulous care, and her expression—solemn, severe, almost stern—radiated an authority that instantly hushed the restless classroom.
"My name is Kirisu Mafuyu. I will be your homeroom teacher from this point forward."
Her voice was strong, her gaze sharp and sweeping. Yet beneath the professional veneer, Akira's system detected the truth.
[Character: Kirisu Mafuyu]
[Potential: A]
[Favorability: ???]
[Status: Anxious]
Anxious? Akira suppressed a knowing smile. First time as a homeroom teacher, then. The stern facade, the rigid posture—all calculated to establish dominance over a room full of unpredictable adolescents. Beneath the ice, she was likely a bundle of nerves.
In the otherwise silent, attentive classroom, Akira's slight, understanding smile was a discordant note. Kirisu Mafuyu's sharp eyes caught it immediately. The boy in the back, middle row—handsome, composed, his gaze holding an unsettling directness. When their eyes met, she felt an inexplicable flicker of... guilt? As if he could see through her performance to the anxious young woman beneath.
What is this feeling? She filed the thought away for later. There was no time to dwell. The opening ceremony awaited.
"Everyone, stand. Line up in the corridor. Single file. Move."
The class obeyed. In the shuffle of bodies finding formation, Akira found himself directly behind Saeko Busujima. The scent of hinoki wood and faint fabric softener wafted from her. He reached out, a gentle tap on her shoulder.
"Hello. I'm Akira. I sit behind you. Pleased to meet you."
She turned, her movements fluid, economical—a martial artist's economy of motion. Her eyes, a warm brown, assessed him briefly. "Saeko Busujima. Likewise."
The exchange was short, a still pond disturbed by a single pebble. She turned forward and continued walking.
But the pebble had landed.
As a traditionalist and a practitioner of the sword, Saeko valued directness and strength. Akira's initiative—approaching her without hesitation, without the awkward shuffling or sidelong glances she usually received—left a distinct, positive impression. His height, his build, the subtle details of his posture and movement... they spoke of someone who had trained. Someone who understood discipline.
The system confirmed it:
[Saeko Busujima - Favorability: 66]
A solid, promising start. Yet her abrupt turn away signaled a barrier. She was not, currently, open to deeper connection.
And she had her reasons.
Last night, her uncle had come. His words still echoed, a venomous whisper in the halls of her memory: Hand over the dojo. Your father's legacy belongs to the family. To me. Refuse, and I will ensure you become nothing but a walking corpse.
She could go to the authorities. The Hero Association. They could offer temporary protection. But her uncle had connections—a whole Gang at his back. And whispers of a darker patron: the Zombie Devil. Protection would never be permanent. Only one solution existed: either her uncle died, or she did. No compromise. No middle ground.
Tonight, she would take her father's katana from its alcove. She would go to him. And she would end this.
[Ding.]
[Temporary Character Quest Detected: Dojo Defense Battle.]
[Accept?]
Akira blinked. Above Saeko's head, visible only to him, a golden exclamation mark pulsed like an NPC's quest beacon in a game.
This works too?
He'd read enough web novels to recognize a quest prompt when he saw one. The question was: what were the rewards? Affection points? Skills? Something more tangible?
He willed the details to expand.
[Quest: Dojo Defense Battle]
[Objective: Prevent the forced seizure of the Busujima Dojo and ensure Saeko Busujima's survival.]
[Context: Saeko Busujima's uncle, a corrupt figure entangled with organized crime, has formed a pact with the Zombie Devil. He has issued an ultimatum: surrender the dojo by midnight, the day after tomorrow, or face lethal consequences. Unbeknownst to Saeko, her uncle is merely a pawn; behind him lies a criminal syndicate and a Devil seeking to expand its territory.]
[Current Situation: Saeko Busujima, unaware of the full threat, plans to take her father's katana and confront her uncle alone. Tonight.]
[Warning: Unassisted confrontation will result in critical failure.]
[Rewards: ???]
[Penalty for Failure: Saeko Busujima's permanent incapacitation or corruption. Relationship lock. Potential S-rank asset lost.]
The procession continued toward the auditorium, students chatting in low murmurs around him. Akira's face remained calm, pleasant, the perfect mask of a new student enjoying his first day.
But behind his eyes, calculations were running at full speed.
Tonight. She's walking into a trap tonight.
The uncle was a thug with Devil backing. Saeko was skilled—S-rank potential didn't lie—but skilled wasn't invincible. Against a Gang and a Devil, alone, with only her father's katana? She would die. Or worse.
And if she dies... The thought was cold, pragmatic. An S-rank asset, lost before I can even secure a physical connection. Before I can train her. Before I can...
He stopped the thought there. It wasn't just about the system. Saeko Busujima, in this moment, was a person walking toward her own grave with quiet, determined resignation. Something in that—the dignity, the acceptance—stirred an emotion he hadn't expected.
Accept.
[Quest Accepted.]
[Dojo Defense Battle - Active.]
[Time Remaining: Approximately 8 hours until Saeko's departure.]
[Recommended Action: Intercept. Assess. Eliminate threats. Secure asset.]
The auditorium doors loomed ahead. Akira's gaze flickered to Saeko's back—the straight spine, the proud carriage, the wooden sword she'd refused to leave behind.
I'll need a plan. Weapons. Intel. And...
His eyes drifted to the other names in his mental registry. Yumi. Yuki. Kato. Alisa. Marin. Kirisu-sensei. Potential assets, potential liabilities, potential...
Allies.
Tonight, he would need more than just himself.
The golden exclamation mark above Saeko's head had long since faded, but the weight of its meaning pressed against Akira's consciousness like a ticking clock.
[Quest Countdown: 39:24:51]
Less than forty hours. And the conditions were brutal: Thoroughly eliminate the hidden danger. Not just repel, not just protect—eliminate. Every member of the Gang. And the Zombie Devil itself.
Akira's mind cycled through threat assessments as the opening ceremony droned on around him. The Zombie Devil, if it matched its Chainsaw Man counterpart, was a hulking monstrosity nearly two stories tall, capable of raising armies of shambling corpses. The main body? Probably Tiger-level by One-Punch Man standards—a threat that could demolish a city block but wouldn't register on the Hero Association's high-priority radar. Its minions, however, were Wolf-level each. Individually weak, but in sufficient numbers, they could overwhelm even a trained fighter.
And I'm supposed to handle all of that, plus a Gang with underworld connections, without touching the Souo family resources?
The old man's test hung over him like a guillotine blade. Use family assets now, and everything—Yuki, the inheritance, the comfortable life—evaporated. But if he failed this quest, he lost an S-rank asset with "absolute loyalty" as a reward. The calculus was agonizing.
A cunning rabbit has three burrows. The old saying surfaced in his mind. He didn't need the Souo family's money. He needed information, preparation, and leverage. And for that, he needed to get closer to the quest-giver herself.
The opening ceremony ended. One more class period crawled by—a blur of introductions, syllabus reviews, and the rustle of new textbooks. Akira absorbed none of it. His attention remained fixed on the radar in his mind, the cluster of dots representing female characters throughout the school. Potential assets, potential distractions. All secondary to the silver-haired kendo prodigy sitting rigidly in front of him.
Lunch break.
The bell rang. Students rose, stretching, chattering, forming groups to descend upon the cafeteria or claim territory in classroom clusters. Saeko Busujima stood with quiet precision, retrieving a neatly wrapped bento from her bag. Without a word to anyone, she walked toward the door.
Akira followed.
Not obviously—he maintained distance, timing his movements to the flow of hallway traffic. But his path was deliberate, his gaze never losing sight of her distinctive silhouette. Up the stairs. Past the second floor. Third. Fourth. Until she pushed through the door to the rooftop.
He waited a measured ten count, then followed.
The rooftop was bathed in midday sun, the city sprawled beyond the chain-link fence. Saeko stood near the edge, her bento balanced on a narrow ledge, her gaze fixed on the distant skyline. She didn't turn as the door clicked shut behind him.
"Student Akira." Her voice was calm, unsurprised. "Do you have a habit of following people?"
So she'd known. Of course she had. A martial artist of her caliber would detect a tail within seconds. Akira allowed a rueful smile to touch his lips as he approached, stopping at a respectful distance.
