The morning sun streamed through the expansive windows of the immense residence nestled in the tranquil suburbs of Tokonosu, Kanagawa Prefecture. Standing before the mirror in his room, Naruto finished drying himself after his morning shower, gazing at his reflection with a mixture of gratitude and awe that, even after eighteen years in this new life, had yet to fade. Physically, he was an imposing figure who drew attention wherever he went. Standing at an imposing 1.90 meters tall, his body was a map of chiseled, dense, and defined muscles, courtesy not only of the Saiyan genetics that now coursed through his veins, but also of brutal and relentless physical training. His skin had a semi-tanned tone, and his face, with its masculine and strikingly attractive features, was framed by unruly, spiky black hair that defied any attempt at styling, with two long strands falling along his cheeks. His eyes, as dark as coal, held the wisdom of two lifetimes.
Beneath the towel wrapped around his waist, his anatomy also reflected an overflowing masculinity, extraordinarily well-endowed by nature with a very impressive penis (lol) accompanied by two large spheres, all in a completely hairless area—a genetic trait he shared with his father. However, beyond his overwhelming physical appearance, what truly filled his chest with warmth was the peace within him.
As he dressed in his casual clothes for walking around the house, his mind briefly traveled back to his past life. He recalled the piercing cold of death after the titanic battle against Kaguya Ōtsutsuki. He had managed to seal her away alongside Sasuke, the "Teme," but the price had been absolute. The extreme exhaustion of his chakra network caused his organs to collapse before Sakura or any of his friends could intervene. He died a hero, yes, but also with the bitter taste of unfulfilled dreams: he couldn't truly become Hokage, he couldn't start a family with Hinata, and he left that world still, deep down, the same orphan who had always longed for a home. But Kami-sama had been merciful. He granted him a second chance, reincarnating him in a completely different universe with a gift that surpassed any ninja technique: biological parents who loved him unconditionally and a house full of siblings.
The sound of a wall cracking slightly and children's shouts pulled him from his thoughts. He smiled. That was the melody of his home.
He left his room and went downstairs in the enormous house, dodging Romanesco and Bardock Jr., ages 10 and 8, who were running at supersonic speeds chasing each other down the hallway. In the living room, his 16-year-old older sister, Furensō, was trying in vain to study while Gohan (14) and Goten (12) argued about fighting techniques. Further on, on the rug, little Paragus Jr. (6), Rock (4), and Toma (2) were building a tower of blocks that was sure to end in an accidental Ki explosion. It was absolute chaos, but for Naruto, it was paradise.
He headed to the master bedroom to fulfill his duty as the eldest son. Upon opening the door, he found his parents packing suitcases in a monumental mess. His mother, Goki—or Kakaroko, as his father sometimes called her—stood in front of the closet holding three tiny swimsuits with an expression of pure childlike confusion. At 36, Goki was a woman of otherworldly beauty and immeasurable power. With her signature spiky black hair resembling a palm tree, pale complexion, and dark, sparkling eyes, she radiated an almost comical innocence. Her figure, standing at 1.70 meters tall, was spectacularly voluptuous; she possessed enormous breasts that threatened to burst the fabric of her combat shirt, a perfectly flat stomach, a wasp waist that flared into wide hips, and a huge, firm rear. Despite being a lethal warrior, her naiveté was her most endearing trait.
"Naruto, my boy!" "What do you think I should wear to the beach?" Goki exclaimed upon seeing him, dropping her clothes to hug him with a force that would have fractured the ribs of a normal human. "Bulma said there's going to be a giant seafood buffet!"
"Wear comfortable clothes, Mom. And maybe something you won't ruin if you decide to train on the sand," Naruto replied, returning the hug affectionately, used to his mother's absentminded nature.
On the other side of the immense room, finishing sealing a Hoi-Poi capsule, was his father, Broly. At 36 years old, Broly was a mountain of muscle and testosterone that commanded respect with just a breath. Standing at a colossal 7 feet tall, his physique was a work of art of warfare, with a semi-tanned complexion, wild black hair, and deep, dark eyes. Like Naruto, Broly was an extremely attractive and extraordinarily well-endowed man, a trait Naruto knew he had inherited directly from him. Despite his intimidating appearance and legendary destructive power, at home he was a man of few words, serene, protective, and deeply in love with his wife. In his arms rested peacefully little Goki Jr., the family's newest addition.
"Thanks for helping us organize this, son," Broly said in his deep, booming voice, approaching and placing a heavy, warm hand on Naruto's shoulder. "I know you'll be in charge of the house and the dojo."
"It's no trouble at all, Dad. You know I love looking after the dojo. Besides, someone has to make sure the twins and the little ones don't destroy Tokonosu while we're gone," Naruto joked, though there was a lot of truth in it.
The trip they were planning wasn't just a simple vacation. They were heading back to their home universe to spend a few days at a private beach resort, a trip organized by Bulma, who would be accompanied by Vegeta, Trunks, and little Bra. The idea was to disconnect from the Earth routine of this universe, where they had to constantly hide their alien nature.
"Yes, it'll be so much fun!" Goki added, jumping up and down with excitement, her generous frame bouncing. "Besides, Broly and I already talked about it. Vegeta's always bragging about how strong his family is, so your dad and I are going to make love nonstop on the beach to give you another little brother or sister. We want at least fifteen kids!"
Naruto felt a bead of anime sweat trickle down his neck as his cheeks flushed a light red. Broly, meanwhile, looked away toward the window, a visible blush rising to his tanned cheeks, though a small, proud smile played on his lips. They were a legendarily active and passionate couple, so much so that their inexhaustible intimate energy and obvious happiness often stirred envy in other couples, especially Vegeta, who couldn't stand seeing "Kakaroko" so absurdly happy and productive.
"T-That's… too much information, Mom." "But I'm glad you're having fun," Naruto managed to say with a nervous smile. "Just make sure you don't destroy Bulma's private island."
The family survived and maintained their comfortable lifestyle in Japan thanks to the martial arts dojo they had founded in the city. Alongside his studies at the prestigious Fujimi Academy, Naruto worked as the head instructor at the dojo with his parents. Teaching humans allowed them to earn money to support their large family and, at the same time, gave them the perfect excuse to justify their superhuman strength under the guise of "extreme conditioning." No one in Tokonosu, not even the government, was prepared to learn that the most athletic family in the neighborhood was actually a pack of aliens capable of destroying the planet with a poorly aimed sneeze. Their golden rule was to remain inconspicuous.
After a few hours of organizing, laughter, and chaotic goodbyes, Goki activated his teleportation. With Broly carrying the luggage and gathering the nine younger siblings into a circle, holding hands, the parents said goodbye to their eldest son.
"Be good at school, Naruto. And if any human bothers you, remember: don't snap their necks, just scare them with your Ki," his mother advised him innocently, before disappearing with the entire family, leaving a sudden and profound silence in the enormous mansion.
Naruto remained alone in the living room, sighing with a mixture of relief and melancholy. He loved his family dearly, but he also cherished these brief moments of peace. He glanced at the clock on the wall; he was running late. He went up to his room and dressed in the black Fujimi Academy uniform. The blazer was a little tight around his shoulders and chest because of his muscular build, but it gave him an air of authority and elegance. He grabbed his backpack, adjusted his shirt collar, and left the house, locking the door behind him.
The weather was perfect. A gentle spring breeze rustled the trees of Tokonosu as Naruto walked toward school, greeting a few passing neighbors. His mind was focused on the exams he would have that week and the training routines he would put his students through at the dojo that afternoon. Everything seemed perfectly normal, routine, peaceful, and boring.
____________________________________________________________
Naruto had no way of knowing. He couldn't have foreseen that that very morning, as he sat at his desk, ready to endure history class, the gates of Fujimi Academy would be struck by something otherworldly. He didn't know that the peaceful Japan he had worked so hard to protect from the shadows was just minutes away from being devoured by an outbreak of a zombie apocalypse that would turn the streets of Tokonosu red and test not only his Saiyan strength but everything he had learned in his two lives.
The usual bustle of Fujimi Academy filled the hallways, but for Naruto, the morning had suddenly turned quiet. With his history teacher absent, the class had been given a free period, giving the young Saiyan a chance to stretch his legs. He walked with his hands in the pockets of his black pants, his imposing height of 1.90 meters and muscular physique making him stand out from the sea of average students. The furtive glances and whispers from the girls as he passed were a daily occurrence, but he ignored them with a mixture of habit and politeness.
As he turned a corner near the teachers' lounge, a female voice, authoritative yet melodic, caught his attention.
"I've told you a thousand times you can't just loiter around the hallways during class time!" the voice exclaimed.
Naruto smirked; he would recognize that tone anywhere. Leaning against the wall, he watched as Professor Kyoko Hayashi finished reprimanding a disheveled-looking student who nodded nervously behind her before running off.
Kyoko sighed in exasperation and turned around, coming face to face with the young man with messy black hair. As always, Professor Hayashi's appearance was a perfect blend of strict authority and undeniable mature appeal. She wore her signature thin-framed glasses that accentuated her sharp eyes, and her reddish-brown hair fell in soft waves around her face. She wore a tight white blazer that, combined with a low-cut yellow blouse, barely contained her generous and voluptuous figure, something that didn't go unnoticed by most of the male students at the academy.
Upon seeing Naruto, Kyoko's stern expression softened instantly, and a slight blush appeared on her cheeks, betraying her strict facade. There was something about Naruto's bearing, in his dark, deep gaze, that denoted an unusual maturity for an 18-year-old, something that always managed to disarm her a little.
"Ah, Naruto-kun..." Kyoko greeted him, adjusting her glasses with an almost nervous gesture as she tried to maintain her professional posture, though the height difference forced her to look up slightly to meet his dark eyes. "Shouldn't you be in history class?"
"The teacher was absent today, Hayashi-sensei. We have the period free," Naruto replied in his calm, confident voice, giving her a kind smile that made the teacher's heart skip a beat. "Trouble with the first-years again?"
Kyoko let out a small laugh, relaxing her shoulders and taking a step closer to him.
"You know the first-years, always finding excuses to skip class. Though I suppose I can't complain to you; You're one of the few students who actually have any discipline. I suppose being a teacher at your family's dojo gives you a different perspective.
"I do what I can. My parents left me in charge while they're away, so I have to set a good example, don't you think?" he remarked, crossing his arms, which made the fabric of his uniform tighten over his well-defined biceps. Kyoko couldn't help but glance down at his chest for a split second before meeting his eyes again.
"It's a big responsibility for someone your age, but if anyone can handle it, it's you, Naruto-kun. You've always been… very mature," she murmured, her tone becoming a little more intimate and personal. They got along surprisingly well; for Kyoko, talking to Naruto was more like talking to a colleague than a teenager.
"Thank you, Hayashi-sensei. If you ever need to relieve stress, the doors of our dojo are always open to you. I promise I'll be a good instructor," Naruto offered with a slightly playful tone.
Kyoko smiled, genuinely flattered by the invitation.
"Maybe I'll take you up on that one of these days. With how stressful things have become lately, a little training wouldn't hurt."
The atmosphere between them was light and pleasant, a welcome break from the school routine. However, just as Naruto was about to continue the conversation, something imperceptible to any ordinary human made him stop in his tracks.
His keen Saiyan senses shot up. A chill he hadn't felt since his days as a shinobi ran down his spine. His dark eyes narrowed, and his gaze shifted quickly to the large windows in the hallway that overlooked the main entrance of Fujimi Academy.
"Naruto-kun? Is something wrong?" Kyoko asked, noticing the sudden change in the boy's demeanor. His muscles tensed like steel springs, and the smile vanished completely from his face, replaced by a calculating, lethal coldness.
Naruto didn't respond immediately. His superhuman hearing picked up a muffled sound, like a heavy thud against the metal gates of the school entrance, followed by a strangled scream that chilled him to the bone. The spring breeze that had seeped through the open windows suddenly carried with it a metallic, stale smell. The smell of blood.
The apocalypse had arrived at their doorstep.

Omake 1
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 that the school nurse needed to see him urgently.
"Marikawa-sensei?" Naruto called, his unruly black hair peeking out from behind the door. "I was told you were looking for me."
From behind the medical screen emerged the unmistakable figure of Shizuka Marikawa. The academy nurse was famous throughout the school, and not exactly for her medical skills. With her long blonde hair, perpetually absent-minded expression, and a figure that defied the laws of gravity and the physics of uniforms, Shizuka was the platonic dream of nearly every male student. Her white coat was strategically unbuttoned, revealing a plunging neckline that barely contained her ample breasts.
"Ara, ara! Naruto-kun, it's so good you came!" Shizuka exclaimed in her sing-song voice, her words slurred as she approached him with a slight bounce with each step that would have mesmerized a normal human. Naruto, however, merely blinked, maintaining his composure. Being raised by Goki had given him a certain immunity to voluptuous, innocent-looking women.
"How can I help you, sensei? Do you need me to move heavy boxes again?" he asked, crossing his arms and leaning against the doorframe.
Shizuka let out a melodious giggle and put a finger to her lips, looking him up and down with a spark of scientific curiosity in her unfocused eyes.
"No, no, it's not that, heavens... You see, the academy's advanced medical department is conducting a study on the physical performance and genetics of our elite students." "Well, Naruto-kun... you're the tallest, most muscular, and most athletic student we have. You're literally the perfect specimen!"
"I guess thanks..." Naruto raised an eyebrow, feeling a bead of anime sweat form on the back of his neck. Something in the nurse's tone told him the conversation was about to take a very strange turn. "So, what exactly do you need? A blood sample? Because I'm not too fond of needles."
Shizuka shook her head, making her blonde hair flutter. She walked over to her desk, opened a drawer, and took out a small, sterile plastic vial with a cap. She approached Naruto and, with the sweetest, most innocent smile imaginable, offered it to him.
"We need a sample of your sperm, Naruto-kun!" she announced with the same casualness she'd use to ask for a glass of water. "And while we're at it, we wanted to know if you'd be interested in being a regular donor for our research bank. You'd be a huge help to the school's science!"
There was a deathly silence in the infirmary.
Naruto felt his soul leave his body for a split second. His dark eyes widened, and a deep blush spread across his semi-tanned cheeks. A sample of what? In a high school?!
"M-Marikawa-sensei?!" Naruto stammered, his stoic warrior demeanor completely gone. "What kind of school has a sperm bank for research?! That's illegal, or at the very least, it violates several ethical codes of education!"
"Oh, don't be shy!" Shizuka puffed out her cheeks, moving a little closer, which caused her ample chest to accidentally brush against Naruto's muscular arm. "It's for science, Naruto-kun. Besides, with your incredible physique and... well, I assume all your proportions are equally extraordinary... it would be a waste not to study your genetics!"
Naruto's internal panic multiplied tenfold. First, if he gave her a sample, the school's microscopes would go haywire seeing Saiyan cells; his alien cover would be blown. Second, remembering his own massive anatomy—a direct inheritance from Broly—he looked at the small plastic vial Shizuka offered him and thought with genuine concern, "Sensei, with all due respect, I'm going to need a much, much bigger vial..."
Finally, he coughed nervously, taking a tactical step back toward the door.
"I-I... I'm very flattered, Marikawa-sensei, I really am. B-But I believe my religion, and the rules of my family's dojo, forbid me... er... donating my vital fluids to school science," he made up on the spot, quickly bowing. "I have to get back to class! See you later!"
Before Shizuka could protest, Naruto vanished down the corridor using a fraction of his supersonic speed, leaving behind only a gust of wind that slightly lifted the nurse's skirt.
"Wow... what a fast boy," Shizuka murmured, blinking slowly and pouting at the empty jar. "What a shame, it would have been a great contribution."
