The interior of the teachers' lounge was a silent testament to the panic that had gripped the academy. Overturned desks, smashed coffee cups on the carpeted floor, and exams scattered like macabre confetti painted a picture of utter chaos. Near the photocopier, a trail of dark blood trailed toward the ventilation duct, indicating that at least one teacher had met a gruesome end before Naruto smashed through the door.
The young Saiyan entered first, his senses operating at a level no military radar could match. His dark eyes scanned every shadowy corner, while his ears filtered the ragged breathing of the fifty students behind him, searching for the distinctive gurgling sounds of the infected.
"Clear," Naruto declared, lowering the bloodied steel pipe. He turned to Kyoko and Saya. "Secure the barricade. Hayashi-sensei, find the keys." Takagi, check the windows and assess the route to the parking lot.
Saya clicked her tongue, annoyed at being ordered around by a classmate, but the cold logic of the situation and Naruto's imposing presence compelled her to obey without question. She adjusted her broken glasses and hurried toward the large windows, while Kyoko hurried toward the key board guarded behind glass in the back wall.
As the students piled chairs and desks against the shattered door frame, an almost imperceptible sound caught Naruto's attention. It wasn't a growl. It was a stifled sob. A rapid, erratic heartbeat, like that of a trapped bird, coming from the small annex that served as a teachers' lounge.
Naruto raised a hand, ordering the crowd to remain completely silent. He moved with feline grace to the half-open door of the annex. He gripped his improvised weapon, ready to crush a grayish skull, and pushed the wood shut with his foot.
In the dim light of the room, huddled beneath a first-aid table and trembling violently, lay Shizuka Marikawa. Her pristine white coat was stained with crimson splashes that weren't hers, and her long, usually perfect blonde hair was a disheveled mess. Her hands were pressed against her ears, muttering incoherently with her eyes squeezed shut.
"Marikawa-sensei?" Naruto called, his voice deep but devoid of hostility, a tone he often used to soothe his younger brothers when they had nightmares about monsters. Ironically, the monsters were now real.
Shizuka let out a small scream of terror and shrank even further, bracing for the fatal bite. When she felt no pain, she slowly opened her tear-filled eyes. As her vision focused on Naruto's imposing silhouette against the light, her lower lip trembled.
"N-Naruto-kun...!" the nurse sobbed. All her usual absentminded, flirtatious demeanor had evaporated, leaving only a terrified woman who had witnessed hell unfold in the hallways. "T-They were eating the principal…! I-I ran and hid here, but… the screaming won't stop!"
Naruto knelt nimbly, sliding the steel pipe through his belt to free his hands. He gripped Shizuka's shoulders with a comforting firmness, transmitting a warmth that belied the chilling, deathly atmosphere.
"Look at me, Sensei. Take a deep breath," he instructed gently, channeling the same patience his father, Broly, used when stress overwhelmed the family. "You're safe now. We're evacuating the school, and you'll be coming with us. But I need you to be strong. I need the nurse from the operational academy, because there are likely to be casualties. Can you do it?"
Shizuka looked at him, her large amber eyes desperately searching for an anchor of sanity. The strength of Naruto's hands, the utter lack of fear in his handsome, masculine face, accomplished what seemed impossible. He swallowed, nodding slowly as he wiped his tears with the back of his hand.
"Y-Yes… I'm a doctor. I-I have to help," she stammered, leaning on the arm he offered to help her to her feet. Her legs trembled, causing her ample chest to rise and fall erratically, but Naruto steadied her with astonishing ease, guiding her toward the main room.
"I've got them!" Kyoko exclaimed from the other side of the room, waving a heavy bunch of keys with metal tags. "The keys to the three buses for the kendo and baseball club."
"It's useless. We're dead. Absolutely dead," Saya Takagi's fatalistic voice cut through any glimmer of hope. She stood pressed against the windowpane, staring out, her face as pale as paper.
Naruto left Shizuka in Kyoko's care and strode to the window, stopping beside the young genius. What he saw in the front parking lot would have broken the spirit of any normal human being.
The wide, paved courtyard separating the main building from the bus parking area was teeming with them. At least three or four hundred infected wandered aimlessly. Former students, teachers, maintenance staff—all reduced to empty shells, thirsting for flesh. They formed a sea of bloodied uniforms and dislocated limbs that stretched like a macabre carpet along the hundred meters they had to cross.
"I reckon a density of four individuals per square meter at the bottlenecks," Saya muttered, biting her thumbnail until it almost bled, her mind processing variables at a frantic pace. "The sound of our footsteps, multiplied by fifty-three people, will attract them instantly. They'll surround us before we're even halfway there. And we don't even know if the buses have enough fuel. It's tactical suicide, Naruto."
Naruto pressed a hand against the glass, his expression turning icy. His mind, forged on the battlefields of the Fourth Shinobi World War, assessed the situation. He couldn't use shadow clones; multiplying his body in front of fifty people would blow his cover. He couldn't use an expansive Ki pulse to sweep the courtyard without incinerating the buses themselves. His immense power, capable of splitting the Earth's crust, was completely useless if he wanted to keep his alien family anonymous.
He would have to do it the old-fashioned way. Pure, brutal, and bloody physical force.
"We're not all going at once," Naruto declared, turning away from the window and facing the group that stared at him with desperate anticipation. "Takagi, you and Hayashi-sensei will organize the people into three columns. The fastest and strongest on the sides, protecting the weakest, and Marikawa-sensei in the center."
"Didn't you hear me?!" Saya hissed, losing her temper. They're going to devour us the moment we set foot on that asphalt!
"They won't, because they'll be too busy trying to kill me," Naruto replied with chilling calm, pulling the steel pipe from his belt. He walked over to a nearby desk and, with a single stomp, broke the heavy metal leg, arming himself with a second, improvised, blunt club under everyone's astonished gaze. "I'll go first. I'll clear a path straight to the main bus and make enough noise to draw the central horde toward my position. You all advance along the right flank, hugging the gym wall."
Kyoko took a step forward, her protective instinct as a teacher clashing with the visceral terror she felt.
"Naruto-kun, that's insane. They're going to surround you. There are hundreds of them… no matter how good a fighter you are, it's physically impossible for you to survive that alone."
Naruto gave him a lopsided smile, an expression that exuded such absolute and unwavering confidence that, for a second, it made everyone forget the apocalypse outside. It was the smile of a leader who had defied literal gods in his past life.
"Don't worry about me, Hayashi-sensei. Just make sure you open the doors of the express bus. When I give the signal, you run for your lives and don't look back. Understood?"
Without waiting for a reply, Naruto headed toward the side door of the teachers' lounge that connected directly to the outside emergency stairs. He pushed the panic bar, and the heavy spring air, now laden with the stench of decay and copper, hit his face.
He descended the three floors, leaping four steps at a time, landing on the asphalt of the courtyard with a thud that immediately turned dozens of gray heads in his direction.
One hundred meters separated him from the buses. Three hundred infected in between.
Naruto closed his eyes for a microsecond. "Mom, Dad... I promise I won't use Ki. Just... a little extra strength," he thought, tightening his grip on his steel clubs until the metal creaked slightly beneath his knuckles.
He let out a scream. A primal, calculatedly human roar that echoed throughout the backyard, drawing the attention of every monster within a hundred-meter radius.
And then, Naruto charged.
It was a vision of choreographed violence and absolute lethality. In the eyes of Saya, Kyoko, and the rest of the students who watched petrified from the staircase, Naruto looked like a force of nature unleashed. He moved with terrifying efficiency. His muscular body twisted and dodged rotting arms with millimeters of margin. The steel pipes in his hands hissed, drawing deadly arcs in the air.
Each impact was a hollow, wet sound that heralded a shattered skull. There were no wasted moves. Block, spin, blow to the temple. Knee-shattering front kick, sweep to take down three, downward impact to finish. Naruto advanced in a straight line, leaving a trail of dead bodies in his wake, drawing the horde toward him like a bloody magnet.
From the stairs, obeying the unspoken command of their sacrifice, Kyoko and Saya began to guide the immense group of students along the gym wall, weaving through the space Naruto was clearing with brute force.
Just as Naruto reached the middle of the courtyard, his keen ears caught the sound of metal hitting bone coming from a different direction. It wasn't his own battle.
He glanced to his left flank, near the garden sheds. A small, desperate group of three was being cornered by about twenty infected who had broken away from the main horde.
Naruto recognized the faces. Takashi Komuro, wielding a dented aluminum bat with an expression of savage fury. Beside him, Rei Miyamoto executed precise thrusts with a makeshift spear fashioned from a broomstick, her face stained with blood and tears. But the one truly holding the line was the elegant and lethal figure of Saeko Busujima. The captain of the kendo club was a hurricane of oak wood, her bokken moving with the speed of a steel blade, crushing heads with a cold, sharp smile on her lips.
However, they were losing ground. The numerical superiority was overwhelming, and fatigue was beginning to show in Takashi's arms.
Naruto clicked his tongue. "I guess fifty-three people weren't enough for my karma today," he thought with inward sarcasm.
Adjusting his trajectory without losing momentum, Naruto diverted his advance like a derailed freight train, forcing his way through the tide of undead with brutal force, heading straight for Takashi's besieged group to prevent them from being devoured before reaching the armored transport.

Omake 3
The unmistakable scent of antiseptic and lavender filled Naruto's nostrils as he slid open the door to the Fujimi Academy infirmary. A few hours before the incident with Professor Hayashi, he'd received a message, delivered by an extremely nervous first-year student, indicating that the school nurse needed to see him urgently.
"Marikawa-sensei?" Naruto called, his unruly black hair peeking through the door, his dark eyes scanning the room with pure foresight. "I was told you were looking for me."
From behind the white medical screen emerged the unmistakable figure of Shizuka Marikawa. The academy nurse was famous throughout the prefecture, and not exactly for her impeccable skills in bandaging sprained ankles. With her long, silky blonde hair, perpetually absent-minded expression, and a voluptuous figure that seemed to actively defy the laws of gravity and the structural integrity of medical scrubs, Shizuka was the platonic dream and primary cause of distraction in gym class for nearly every male student. Her white coat was strategically unbuttoned at the top, revealing a plunging neckline that barely contained her immense assets.
"Ara, ara! Naruto-kun, it's good you came so fast!" Shizuka exclaimed in her characteristic sing-song voice, dragging out the syllables as she approached him. Each step she took was accompanied by a slight but hypnotic bounce that would have paralyzed the reptilian brain of any normal teenager.
Naruto, however, merely blinked, maintaining an upright posture and steely composure. Being raised by Goki, a woman with equally ridiculous proportions but the strength to split continents in two, had granted him an enviable immunity to the visual charms of voluptuous, innocent women.
"How can I help you, Sensei? Do you need me to move the medical filing cabinets or the heavy stretchers again?" he asked, crossing his arms, the fabric of his school uniform straining against his well-defined biceps as he leaned casually against the doorframe.
Shizuka let out a melodious giggle, bringing a pink-painted finger to her lips. She looked him up and down, a spark of genuine scientific curiosity shining in her large, usually unfocused, amber eyes.
"No, no, it's not that, heavens… You see, the academy's Department of Advanced Biology and Sports Medicine, in conjunction with a university in Tokyo, is conducting a very important study on the physical performance, endurance, and genetics of our elite students." And well, Naruto-kun... you're the tallest student, with the densest musculature and the fastest metabolism we have on record. Your physical exams were phenomenal! You're literally the perfect specimen for our research!
"I suppose… thanks for the compliment." Naruto raised an eyebrow, feeling a massive, anime-style bead of sweat form on the back of his neck. His shinobi senses, honed in bloody battles in another life, warned him that this conversation was about to enter extremely dangerous territory. "So, what exactly do you need for this study? A blood sample? Treadmill stress tests? Because I'm warning you, I'm not a big fan of needles."
Shizuka shook her head vigorously, her blonde hair and curves bouncing in a way that forced Naruto to glance up at the ceiling for a second to maintain a sense of decorum. She walked over to her glass desk, opened a sterilized drawer, and took out a small, clear plastic bottle with a red screw-on cap. She approached the imposing young man and, with the most innocent, sweet, and maternal smile imaginable, offered it to him.
"We need a sample of your sperm, Naruto-kun!" "—he announced with the same naturalness, joy, and lightness with which he would ask to borrow a pencil or a glass of water—. And while we're at it, we wanted to know if you'd like to be a regular donor for our genetic research bank. You'd be helping school science and the future of humanity immensely!"
There was a deathly silence in the infirmary. The ticking of the wall clock seemed to stop.
Naruto felt his soul, hardened by ninja wars and ki battles, leave his body for a microsecond, floating in the limbo of pure shock. His dark eyes widened, and an intense adolescent blush, betraying his eighteen biological years, spread across his semi-tanned cheeks. A sample of what?! At a public high school?!
"M-Marikawa-sensei?!" "What kind of academy has a genetic collection project?!" Naruto stammered, his deep voice losing a couple of octaves and his stoic warrior demeanor crumbling like a house of cards in a hurricane. "I'm pretty sure that breaks at least fifteen of the board of education's ethical codes and several international laws!"
"Oh, come on, don't be shy, Naruto-kun!" Shizuka puffed out her cheeks, pouting adorably as she took another step closer. The proximity caused her generous cleavage to accidentally, but firmly, brush against the Saiyan's tense arm. "We have all the permits, I assure you. It's all in the name of science. Besides, with your incredible physique, that impressive height, and… well, medically assuming all your anatomical proportions are equally extraordinary… it would be a true crime against science to waste your genetic potential!"
Naruto's brain started working at lightning speed. His first instinct was to use the Flying Thunder God Technique and appear on the other side of town. But then, cold shinobi logic took over.
If he flatly refused and ran away, a woman as stubborn and absentminded as Shizuka would probably keep insisting. Worse, she might complain to the administration or Professor Hayashi about his "lack of civic cooperation," which would draw unwanted attention to him. On the other hand, if he handed over the sample, the university's microscopes would instantly detect cells with an impossible mitochondrial density, strange ribosomes, and chromosomes that screamed "alien planet conqueror"; his precious human cover would be blown to bits.
However, there was a third option. "If I apply a microscopic, constant burst of Ki to the sample just before handing it over..." he calculated mentally, "...I can fry and neutralize the most obvious Saiyan DNA sequences. I would leave intact just enough to make it look like the genetic material of an extraordinarily healthy and strong human. No one would suspect a thing, and I'd get rid of the nurse."
He let out a long, heavy sigh, closing his eyes in resignation. When he opened them, the blush had faded slightly, replaced by an expression of tactical defeat.
"Alright, Marikawa-sensei. You win," Naruto murmured, nervously scratching the back of his neck. "If it's to help the school and... science, I suppose I can cooperate. I accept."
Shizuka's face lit up like a Christmas tree. She jumped slightly, clapping enthusiastically.
"Wonderful! I knew you were a good boy, Naruto-kun!" she sang happily, extending the small 50-milliliter plastic bottle toward him. "The bathroom is right behind that door. Take all the time you need, relax, and don't worry, there are medical journals in the magazine rack if... you need some scientific inspiration."
Naruto looked down at the sterile bottle the nurse was holding. It was tiny. Insignificant. Ridiculous.
His mind instantly traveled to the stark and overwhelming reality of his anatomy. As the biological son of Broly, a colossus over two meters tall and pure muscle mass, Naruto had inherited not only his strength and ki, but also proportions that bordered on the titanic below the waist. Nature had endowed him with overflowing masculinity, and the amount of vital volume his hyperactive body and alien metabolism produced... definitely wasn't going to fit in there. If he used that container, he was going to cause a disaster on the infirmary floor.
Naruto cleared his throat, feeling the heat rise to his ears again.
"Um... Sensei..." he began, pointing at the tiny vial with his index finger, avoiding direct eye contact with her. "With all due respect to you and the scientific community of Tokyo... I think we're going to have a slight logistical problem."
"A problem? What kind of problem?" "—asked Shizuka, tilting her head, genuinely confused, blinking her large eyes.
Naruto swallowed. There was no subtle way to say this.
"That container… it's too small," he confessed, his voice barely a deep murmur. "My genetics… I mean, my father's inheritance… is a bit overwhelming. If I try to use that, I'm going to stain your sterilized floor, sensei. Don't you have anything… bigger? Like… industrial size? Or maybe a half-liter beaker?"
Shizuka blinked once. Then twice. Her brain, usually slow to process the world around her, suddenly made the necessary anatomical connections based on the request from the enormous teenager in front of her.
The color red rose from the nurse's plunging neckline, climbing up her neck until it stained her entire face a brilliant crimson. Her eyes widened as her gaze instinctively drifted down to the midsection of Naruto's uniform pants, her medical imagination running wild.
"O-Oh... my God!" Shizuka gasped, bringing both hands to her burning cheeks, feeling a sudden heat in the air. "I-I... What a marvel of evolution! W-Wait a minute, Naruto-kun!"
Completely flustered, Shizuka whirled around clumsily, tripping over a wheelchair as she hurried toward a sealed supply cabinet at the far end of the room. The sound of boxes falling and glass clinking filled the air until she finally returned triumphantly. In her hands, she held a large, thick-glass graduated beaker, designed to collect substantial samples of intravenous fluids, with a capacity of nearly 800 milliliters.
She handed it to Naruto with trembling hands and slightly ragged breathing, her usual absentminded expression replaced by an intense gleam of wonder and curiosity.
"H-Here you go! Take your time, Naruto-kun! Science isn't in a hurry with such a specimen!" he stammered, trying to maintain his professional dignity while fanning his face with a clipboard.
Naruto took the enormous glass, feeling as though he had just sacrificed what little dignity he had left in this life. With a solemn nod, he turned on his heel and walked toward the door of the adjoining bathroom.
"Kami-sama... Old Sage of the Six Paths... Mom, Dad..." Naruto prayed mentally as he locked the bathroom door, staring at the monstrous glass in his hands. "Forgive me for what I'm about to do in the name of science."
