Dragon Ball: Kayn's Story

Master Roshi was quite frustrated, after all he was very eager to receive the reward for his help, but Kayn's insistence on not letting Bulma be alone with him made him have to give up on it.

The old man was a very blatant pervert, but he wanted to hide it from everyone else, especially his disciple.

Kayn approached Bulma and said in a low volume "Roshi may be a good person and the greatest martial artist, but he is also a pervert, don't trust him too much"

If it were just memories from that life, he wouldn't know much about it, but since he knew the story from the anime, he knew the old man's personality well.

Even though this was taken to the comical side of the story, and the old man hadn't gone any further in his perversions, Kayn still couldn't just let that happen.

'In the end, it would be Oolong who would be groped, but that would certainly give the old man the idea that Bulma accepts his perversions' Kayn thought.

Together they walked through the rubble of what had been a decade ago the tiny kingdom of which the Ox King had ruled.

Bulma could notice some human bones and it made her feel a slight chill, but she calmed down, remembering what Kayn had said.

It wasn't hard to see how much of the rubble was riddled with bullet holes, as if it were a war zone. The flames on the mountain made it impossible to live in that place, because of the heat, but the houses would be almost intact if it weren't for the many attacks by greedy bandits.

As everyone followed the old man, who seemed to want to get closer to the mountain, the Ox King spoke to his son "I didn't think you would find him so soon, it's only been a few hours, how did you find him? And who are these other young people?"

Without slowing down, Kayn said, "Well, we didn't find him, so I don't even know where he's living, but we found these three coming here..." He explained everything that had happened, without going into too much detail, just what was important.

Hearing the explanation, the Ox King looked at Goku "So this little boy got the flying nimbus from the master?... Wait, is that what I think on his back?!"

Kayn intended not to understand, since he had no memory of it in this life, but he knew exactly what it was and the reason for his father's surprise.

Goku noticed the attention, so he asked "What's wrong? Is there something on my back?" He started to squirm, trying to see his back.

"Boy, is that Nyoi-bo?! Where did you get that?" The Ox King questioned, with a clear expression of enthusiasm.

The spiky-haired boy touched the object attached to his back, a mixture of nostalgia and happiness on his face "This was a gift from my grandpa!"

"Your grandfather?! Are you by any chance Son Gohan's grandson!?" The huge man asked, his eyes wide.

Hearing that conversation, Muten Roshi, who was ahead, stopped his steps and turned around, showing a look of surprise. With that, everyone stopped as well and looked at Goku.

"Did you know my grandfather?" The boy raised his eyebrow excitedly.

"Of course he knows him" Master Roshi chimed in "Both the Ox-King and Son Gohan are my best disciples, these two are almost brothers"

"Seriously?!" Goku was impressed.

A wide smile appeared on the Ox King's manly face "I haven't seen Son Gohan in so long, how is he?"

Hearing that, a bitter expression appeared on Bulma's face, she knew there would be no good news.

"Grandpa died a while ago" Goku said regretfully.

The two, who had been excited to learn that the boy was the grandson of an old acquaintance of theirs, soon became distressed.

Neither of them said anything for a while, and the old man continued walking, letting out a helpless sigh.

"This should be enough" The old man said, staring at the burning mountain.

With the exception of Kayn, everyone was looking on curiously, wondering what he would do to deal with the flames.

'That'll probably destroy most of the treasures... Well, not that it matters, after all I have the richest girl on this planet by my side' Kayn smiled, giving Bulma a brief glance.

In this world, money was one of his least concerns, but he didn't want his sister to be like in the anime, so worried about money. He didn't know if Gohan would still exist with his interference, but he hoped that Chi-Chi wouldn't bother him so much about his studies.

Meanwhile, the old man unbuttoned his white shirt, then took it off, revealing his thin, almost skeletal body.

Bulma gave a suspicious look, she wondered if Master Roshi was really trying to put out the fire, or was it just something else strange.

The old man climbed onto some rubble, then took a deep breath "Hah!" Suddenly, his skinny body filled with muscles, to an abnormal level.

Everyone was impressed, especially Bulma and Oolong, who were wide-eyed.

Kayn made a thoughtful expression 'This must be similar to those super saiyan forms, which have a lot of strength, but slow down... Even though this is a double-edged sword, it would be good to learn this, maybe I can develop my own kaioken from this'

Master Roshi stretched out his arms, almost making a cross pose, with his palms open "Ka..." He began to chant vigorously "Me..." His hands slowly came together "Ha..." His wrists touched "Me..." He pulled both hands to the left side of his waist, as if he was gaining momentum, then shouted "Ha!!!" Pushing his palms forward, releasing a blue beam.

The glow of blue energy was visible to everyone, but it only lasted for a moment, followed by a loud explosion on the mountain.

The impact caused most of them to close their eyes. Bulma slowly opened her eyes, then she saw the figure of the old man, who had already returned to his thin state, when she looked in the direction of the mountain, shock filled her face.

Even Kayn, who already knew what would happen, couldn't help but feel a slight shiver, after all, the entire mountain had been erased.

The shock was general, even Yamcha who was at a distance held himself back from letting out a cry of surprise.

A mountain being destroyed could be something irrelevant in the future, where each character could destroy planets, but at that moment, that was the power worthy of a deity, not a human.

There was no longer any room for doubt, this was the well-known Master Roshi, the greatest martial artist on Earth.

Climbing down from the rubble, the old man picked up his shirt from the ground. As he dressed, he looked at his disciple "I'm sorry, I was hoping to take the flames and maybe part of the mountain, I didn't think I still had enough strength to take the whole mountain"

While he really seemed to feel bad about destroying the mountain and the castle, he also seemed to be a little proud and pleased at having such power.

Looking at where a large mountain had once been, the Ox King could see some debris from the castle. It was not the target of the attack, so even though the impact had destroyed it, it had not been evaporated like most of the mountain.

Giving a sincere look of gratitude, he said "Don't worry, master, once the flames are gone, we can rebuild the castle and the people will be able to live here again"

Chi-Chi also seemed fine with the outcome, part of it was because she had no attachment to the castle, she didn't even have clear memories of living there.

Meanwhile, Bulma had a flash in her mind "The dragon ball!" The fear that the explosion had destroyed the object filled his mind.

Taking the dragon radar, she looked at it anxiously, then a sigh of relief escaped her lips, nothing had changed, the radar still indicated that there was a dragon ball right there.

Kayn saw Bulma's concern with a smile, so he stepped forward and approached the girl "The mountain was destroyed, but a magical object like that wouldn't be destroyed so easily. But I think we'll have to search through the rubble, do you want help?"

Bulma quickly agreed "Yes, it would be great if you could help me" She said with an excited smile.

As the two of them, along with Oolong, headed towards the castle's rubble, Goku approached the old man.

"That skill was amazing! Could you teach me it?" He asked excitedly.

The old man smiled with a proud expression, then rubbed his white beard "It is indeed an amazing technique that I developed, but it is not something simple, it took me 50 years to perfect it to this point"

"50 years?!" The boy made an incredulous expression.

"I know it may seem frustrating, but martial arts require a lot of dedication, so it's only natural that it would take years to develop such a high-level technique. If you're as talented as your grandfather, I believe that with a few years of training..." Master Roshi was speaking, but stopped mid-sentence when he noticed something.

Goku had stopped listening to him and was repeating the movements, then "Ha!!!" A blue beam came out of his hands and hit the wall of one of the destroyed houses.

The impact made a fist-sized hole in the wall, Goku looked at it and sighed "It was very weak, I really need to train a lot to do it like Master Roshi"

The Ox-King, Chi-Chi, and even Master Roshi himself were all shocked by the fact that Goku managed to replicate the Kamehameha, even if it was at a much lower power.

"Kid... What do you think about training with me?" The old man asked.

...

Meanwhile, in the ruins of the castle, Kayn had a large number of necklaces around his neck, a pair of rings on each of his fingers, and a crown on his head.

"Piggy, make sure you put everything in the bag, if anything appears in your pockets later, we'll be in trouble" He said, as he looked at Oolong.

Since there were treasures amidst the rubble, he couldn't just leave everything there, he had to collect it, so while they searched for the dragon ball, he also collected the treasures.

Oolong was forced to help, so he had a sack in his hand, keeping everything of value inside. You could hear him grumbling, but he didn't dare steal anything from that place.

Bulma was focused on finding the Dragon Ball, but she had a lot of difficulty doing so, as the Dragon Ball seemed to be buried in the rubble.

She managed to move some smaller rocks with difficulty, while Kayn casually tossed the rubble away to make the search easier.

The girl couldn't help but admire his physique, for someone younger than her, he was very tall and muscular, and even his face was handsome.

"Kayn... Are you sure you're fifteen?" Bulma asked, as she paused in her search.

Hearing that, Kayn laughed "Do you think I lied about that? You saw how tall my father is, I think it's normal for me to be like that too, but I don't think I'll be the same height as him" As he spoke, he continued to throw pieces of stone away as if they were weightless.

"That's right..." Bulma said, but in her mind 'Actually I was referring to those muscles, but it must also have some relation, right?'

Kayn could notice the girl's gaze on his body, so he returned the gaze 'She really is desperate for a boyfriend... Should I take advantage of this? She's pretty, smart, and has a sexy body...'

He knew Bulma's situation, he would probably need half a sentence to start dating her, but that would be taking advantage of her current vulnerability...

Author's Note: I'm honestly in doubt whether I should make the two of them date or not. If anyone wants to give their own opinion, they can do so.
