Goku goes back in time

The tour continued deeper into the high-tech corridors of Capsule Corporation, the students wide-eyed at the sheer scale of technology around them. Lab doors lined the hallways, each hiding secrets and inventions leagues ahead of anything they had seen in textbooks.

"So... is this what rich people see every day?" Sharpner muttered, gawking at a hovering lab drone.

"I still can't believe Gohan practically grew up here…" Erasa said with a mix of awe and suspicion. "And now we know Trunks is a Bulma's son too?"

"But then who is the father?" asked Videl confused.

Before anyone could respond, a door slid open with a cheerful chime, and two small figures bolted out, laughing loudly.

"C'mon, Goten, race you to the garden again!"

"No fair! You started first!"

It was Present Trunks and Goten, both no older than seven, and already full of boundless energy. They zipped down the hallway, zipping past the group like blurs, until—

SMACK!

They bounced into the crowd of students, crashing to a halt like cartoon characters running into a wall (Gohan).

Present Trunks rubbed his head.

"Oww… Hey! You look just like—" started a random student

"…Me," Future Trunks finished with a sigh.

The entire class went silent.

Erasa blinked. "Wait… there are two Trunks?"

Sharpner looked at Present Trunks(Purple hair), then Future Trunks(Blue hair), back and forth like a confused dog. "What—how—huh!?"

Videl's eyes narrowed, brain already spinning. "Okay, something is seriously weird here."

From behind the kids, heavy bootsteps echoed down the hall. Enter Vegeta, arms crossed, scouter long gone but his scowl still the same as ever.

"Trunks. Get your act together." Said Vegeta as he saw Future Trunks in the crowd. "Both of you."

Present Trunks winced. "Sorry, Dad…"

Future Trunks gave a respectful nod. "Father."

Vegeta raised a brow at the older version of his son, then glanced at the stunned students gathered behind him.

"And who are these gawking humans?"

Gohan stepped forward nervously. "Uh, they're our classmates. We're on a school field trip."

Vegeta's eyes narrowed. "And Bulma thought this was a good idea?"

Goten grinned. "Hi, Gohan!"

Gohan smiled and patted Goten's head. "Hey, little bro."

Another wave of shock rippled through the students.

Erasa's mouth dropped open. "He's your brother?!"

Videl squinted. "There are two Trunks. Gohan grew up here. the Goku look a like is his brother… and wait—" she looked at Vegeta, realization dawning, "—Bulma's married to him?!"

The group turned to stare at Vegeta, who scowled even harder.

"What?" he growled. "Is there a problem?"

"Isn't he like... the most dangerous man alive!?" Sharpner blurted out. "I saw a footage where he beat up most of the soldiers from the King of the worlds army! Unarmed!"

Vegeta shrugged. "They got in the way."

Future Trunks sighed. "He's actually mellowed out. This is him being calm."

Gohan chuckled nervously. "Yeah… believe it or not, he's on our side."

Still dumbfounded, one student asked, "Wait, why are both of you named Trunks? Wouldn't that get confusing?"

Vegeta scoffed and crossed his arms proudly. "We are a proud warrior race. Our naming conventions are bound in tradition. I was named after my father. He was named after his. And so on."

"...So basically, you liked the name Trunks so much and named both your son Trunks?" Sharpner asked.

Vegeta's glare could've vaporized concrete. "Watch your tone, boy."

"Eep—yes, sir."

Erasa tried to lighten the mood. "Well… they do look adorable together." She looked between the younger and older Trunks. "It's kind of cute! Like 'little bro' and 'big bro' from a sitcom."

Present Trunks pouted.

"Not kind of, we are brothers after all" he said and then shouted "Hey! I'm not adorable."

"Yeah!" Goten chimed in, fists raised. "We're warriors!"

The class chuckled, some nervously, others genuinely entertained.

Future Trunks crouched and ruffled his younger counterpart's hair. "You'll grow into it. Just keep training."

Vegeta grunted. "Good encourage him. The last time he trained with Chibi Kakarot, they just complained none stop and almost blew up the roof"

"They did blow up the roof" came a voice from the speaker. It was Bulma, chiming in from the central lab. "And don't act like you weren't proud of it, Vegeta!"

Vegeta looked away. "Tch."

As the class continued the tour, many students were still trying to wrap their heads around what they just witnessed.

Two Trunks. One small, one their classmate. Gohan being essentially family with one of the most powerful women on Earth. A mysterious warrior race with dangerous pride and weird naming traditions.

"I feel like I'm in a superhero comic," one student whispered.

Videl stayed quiet, watching Trunks and Gohan interact with everyone. She'd always felt something was off about them—about their calm demeanor and explosive strength. And now… now it was starting to make sense.

Very dangerous sense.

The sun had already begun to dip low, casting warm golden rays over the courtyard of Capsule Corporation. As the tour continued, the students of Orange Star High School stood before Vegeta, Present Trunks, and Goten for one last goodbye.

"Thank you for your time!" Erasa beamed, bowing politely.

"You were… cool," Sharpner admitted reluctantly to Vegeta, scratching the back of his head.

Present Trunks waved. "Come back sometime! We'll show you the gravity chamber!"

"Bye!" Goten grinned. "Let's play again, big bro!" he added, clinging to Gohan's leg before Vegeta cleared his throat sharply.

"Enough clinging. Let's not soften the next generation too much," Vegeta muttered.

As the students filed back into the main research wing, Bulma was already waiting for them in a crisp lab coat and heels, holding a small tablet. Her bright blue hair shimmered under the indoor lights, and she gave a confident wave to the class.

"Well, well! If it isn't Gohan's crew of merry classmates," she teased with a wink. "Hope the tour didn't scare you too much."

The class chuckled nervously. Even the most skeptical of students had begun to suspect there was more to this family than they let on.

Bulma continued, "I'm Bulma Briefs. Head of Capsule Corp, genius inventor, and yes… that Bulma."

She gestured toward a high-tech console as it whirred to life. "Let's move on to the academic side of your visit. I'm giving a short lecture and demonstration on capsule technology and how it's revolutionized the way we store and use matter."

Gohan whispered to Trunks, "She really gets into lecture mode fast."

"She always does," Trunks replied, smiling slightly.

Bulma tapped the screen. Diagrams, blueprints, and interactive visuals appeared in mid-air, floating above a holographic table. She spoke animatedly about compressed matter, density distribution, quantum containment layers, and the early failures of her prototypes.

Despite the complexity, the class was absolutely riveted.

"…and yes, that's how we managed to shrink a yacht into something the size of a pill." She smiled smugly. "Beat that, smartphones."

When she was finished, the students clapped — some impressed, others genuinely bewildered.

Then came the questions.

"How did you manage to stabilize the energy signatures?" asked a tech-savvy student.

"Do you ever patent your work internationally?" asked another.

Bulma answered each smoothly.

Then a hand shot up — this time from a student in the back, cheeks slightly red.

"Um… this might be personal, but—how did you, of all people, end up married to the most dangerous man alive?"

The class went silent.

Even Gohan and Trunks stiffened.

Bulma blinked, then burst out laughing.

"Haha! Oh, trust me — I ask myself that question a lot."

The class laughed along, the tension breaking. But Bulma waved her hand and continued, more softly this time.

"But honestly? It's complicated, just like any relationship."

She glanced briefly toward the hallway where Vegeta and the Kids had been a few minutes ago.

"When I first met Vegeta, he was… well, kind of a menace," she said frankly. "Arrogant, angry, and absolutely impossible to deal with. He came from a warrior race that didn't exactly teach compassion."

She paused, then added with a grin, "I think he still thinks 'I love you' is a weakness."

More laughter.

"But beneath all that pride… he was broken. Alone. A man who lost his home, his family, and his purpose. And maybe I saw something in him that he couldn't even see in himself."

The room went quiet. Even Sharpner leaned in.

"Then he stayed," Bulma said softly. "Not because he had to. But because he wanted to. And over time… he changed. Not all at once, not perfectly. But enough."

She tapped her tablet again. A photo appeared of her, Vegeta, and little Trunks, smiling awkwardly in front of a picnic table.

"That's what love is, I guess. Not just about finding someone perfect — but someone willing to grow."

The silence held for a moment longer before someone started clapping, followed by others. Erasa wiped her eye discreetly.

"Anyway!" Bulma said, regaining her energy. "Let's finish the tour with a trip to the gravity chamber! It's where we make the magic happen."

As the class followed her out of the lecture hall, Videl lingered behind, thinking deeply. Trunks caught her glance.

"What's on your mind?" he asked.

Videl looked at him, then toward Gohan ahead of them. "…Nothing. Just trying to put all the pieces together."
