The silence was awkward – at least, on the Z Fighter's side it was.

"So, how do you know about Father?" Gohan asked curiously, breaking the stiff silence within the rocky clearing.

Kagome was eager to answer, staring at Gohan one could call adoring eyes, though Trunks was the only one who knew why, "We've actually only heard stories of him. We haven't met."

"Then, how do you know that Goku will land here in three hours?" Krillin asked, a bit perplexed on who these people were and how easily they defeated Frieza and his father.

"Ah, forgive us, but I cannot give you that information." Trunks did look sincerely apologetic, though Vegeta would have nothing of it.

"What do you mean you can't say?" Vegeta snarled, rather pissed off at these two for just showing up, "Who are you? And why do you both have so much power?" He was slightly surprised that the female could even transform into a Super Saiyan and he felt yet another hit to his unrelenting pride.

Kakarott and even these two unknowns could go Super Saiyan, so why couldn't he?

Krillin was quick to interrupt, not wanting Vegeta to rile the two powerful beings up, "When you killed Frieza, you both were Super Saiyan, weren't you?" He asked questioningly.

"Yes, that's correct." Trunks answered, though Vegeta only grew angrier in response.

"Cut the crap! Counting me, Kakarott, and the half-breed kid – there's only three Saiyans left! There is no way you two could be Saiyan!" Vegeta growled, his scowl darkening when the two simply remained silent.

"Yeah, but we saw them turn Super Saiyan with our own eyes." Gohan shrugged, coming to the strangers' defence.

"All Saiyans are black-haired anyway, so there's no way that the boy could be one!" Vegeta scoffed, only referring to Trunks' lavender hair because Kagome had the black hair required.

Bulma observed the two, her keen eyes catching something important, "You have the logo of my family's Capsule Corporation on your clothes," She noted, "Are you employees?"

Kagome stared, resisting the urge to just jump at the woman and hug her to death, "N-not exactly." Trunks was quick to answer, seeing that Kagome was too busy staring at Bulma.

"So, then your names are confidential, too?" Bulma asked, looking a bit disappointed.

"Well, we can't tell you our names, but we can say that we're seventeen-years-old." Trunks' apologetic expression came back.

"It's a bit strange that you can't tell us your names." Yamcha said suspiciously, still a bit wary about the two strangers.

Bulma quickly came to their defence, "Stop with the personal questions! You're making them feel awkward!" She smiled widely, "They did just save us from Frieza, after all!" She winked, though looked a bit surprised when she noticed that both Trunks and Kagome were lightly blushing at the praise.

The Z Warriors made themselves a bit more comfortable, though some were still looking warily at Trunks and Kagome, particularly Vegeta, Piccolo, Yamcha, and Tien.

Kagome sighed, kicking out her feet with boredom and she leaned against Trunks' shoulder. She felt him tense, probably because he didn't want to show any too familiar affection between them, but she didn't care. She glanced up, her blue eyes kept on straying to Vegeta, despite her trying not to.

Vegeta's glare towards them did not relent in the very least.

"Don't you think there's kinda a resemblance between them?" Bulma asked quietly of Krillin and he only blinked questioningly at her, "Between that boy and girl and Vegeta. The girl looks a lot like him and the boy has a similar air around him."

Krillin looked back at the two strangers, vaguely seeing a resemblance. He shrugged, choosing not to say anything at the moment.

"Why have you been staring at me for the last while?" Vegeta snapped, fed up with the girl who kept on glancing up at him, "If you really are a Saiyan, then I shouldn't be such an unusual sight!"

Kagome jumped, looking away with a flustered expression, "I-I'm sorry!" She quickly and politely apologised, slumping against Trunks even more. She felt him rub her back in comfort, though it didn't really work as intended.

"Three hours have passed. Son Goku should be landing at any minute." Trunks looked at his watch, standing up from the rock as Kagome followed him and everyone glanced up into the sky.

"H-he's right! I can feel Goku's Ki!" Tien said in surprise and most of them gasped when they noticed something in the near distance.

"It's Dad! He's here!" Gohan cheered, looking very excited as the small spaceship crash landed not too far away from them. Everyone was instantly on their feet, peering over the smoking crater and observing the spaceship with shock.

The door opened only a second later and Goku stepped, looking just as surprised as them, "How come you guys are all here?" Goku blinked, though everyone ignored the question as a few began to cheer, "How did you know I was going to be landing here?" He flew from the spaceship, landing in front of his companions.

"These two! This boy and girl told us that you would be arriving here!" Bulma gestured to Trunks and Kagome, who were staring at Goku intently.

"You know them, right, Dad?" Gohan asked eagerly, though Goku only looked at the two with a blank and curious expression.

"Who are you?" Goku asked, surprising everyone with his answer.

"You don't know them at all?" Bulma pressed, and Goku only shook his head negatively, "But they knew when you would return here, Goku-kun."

"Really? That's strange!" Goku looked puzzled, but didn't linger on it too long, "Who was it that defeated Frieza? It was some pretty awesome Ki!" Goku grinned, looking at Piccolo, "Was it you? Or even Vegeta?"

Piccolo crossed his arms over his chest, "These two killed Frieza, and it only took a split second," He explained, and Goku glanced over to the two curiously, "And what's more, they can become Super Saiyan like you."

"A Super Saiyan?" Goku blinked, observing them intently, "That's impressive, especially for ones so young!" He grinned brightly, "I didn't even know there were other Saiyans out there!"

"Because there isn't! There aren't anymore Saiyans other than ourselves!" Vegeta quickly snapped and Goku only tilted his head in response.

Kagome stared in awe at the man, trying to keep her excitement internal as Trunks finally spoke, "Son-san, we need to have a word with you," He said, and Goku pointed at himself blankly, "Alone."

Goku frowned, nodding as the others looked a bit confused, "All right." His expression turned a bit more serious and the two led Goku away from the others.

"We can't even know?" Yamcha huffed, though Goku only apologised to them.

Piccolo narrowed his eyes, easily able to hear their conversation even at the distance they had pulled away because of his largely sensitive hearing.

"I'm sorry for my bad manners! I'm sorry that you had to knock off Frieza for me!" Goku grinned warmly, "Maybe I went too easy on him?"

"It's not a problem!" Kagome eagerly said, "They were supposed to be defeated by you, but a little time discrepancy got in the way."

"Yeah. Frieza's ship was faster than mine, so he passed me! He didn't seem very sorry for what he did, so I was going to put him away for good!" Goku frowned a bit, "It's good that you two stepped in, or else I would have had to use my new technique!"

Both half-breeds blinked, "New technique?" Kagome questioned for the both of them.

"Yeah!" Goku looked at the female brightly, "It's known as Instant Transmission. The folks on a planet called Yardrat taught it to me!"

"Wow, that's amazing!" Kagome looked astounded, though Trunks did not look too pleased, "We didn't know that you had such a technique, Goku-san!"

Trunks stared at the ground, "We've changed history for no reason," He suddenly said, catching Kagome and Goku's attention, "And we were only supposed to meet with you, Son-san, but we've run into all the others as well."

"Change history? What are you talking about?" Goku looked puzzled.

"Before I answer, I would like to ask you a question," Trunks said, taking control of the conversation, "Son-san, are you able to become a Super Saiyan on your own will?" He asked seriously.

"Yeah! At first I couldn't, but I finally managed to get it under control!" Goku nodded, answering the question.

Kagome blinked, glancing over to Trunks, "Are we going to test him?" She asked quietly, and Trunks barely nodded his head while not taking his eyes off of Goku.

"May I ask that you turn Super Saiyan, right here and now?" Trunks' indifferent look came back, "Please."

"You got it!" Goku frowned, raising his Ki so suddenly and to immense heights as a golden sheen appeared over him; his features changed from their original black, "Is this okay?"

"Thank you very much." Trunks said, looking rather amazed, though he almost lost balance when Kagome suddenly latched onto his arm tightly while trying to keep her excitement in check.

"It's amazing! You look a lot like us as a Super Saiyan! Well, you resemble him more than me because of your hair..."

"So what now?" Goku asked, observing the two with keen eyes.

"We will also become Super Saiyan." Trunks said, and soon as he was finished with his words, both Trunks and Kagome raised their Ki and the same process that happened to Goku happened to them.

"We do look a like." Goku furrowed his eyes, looking more so at Trunks because Kagome's blond hair did not stand on end like theirs did.

"Please excuse me," Trunks said suddenly, grasping his sword from his sheathe and aiming it directly for Goku's face. However, Trunks stopped as soon he realised that Goku did not move an inch to dodge, "Why didn't you try to avoid my strike?" Trunks asked, lowering his sword.

"Your Ki had no killer intent. I knew you would stop." Goku smirked.

"Very well, then. This time I will not stop. Do you understand?" Trunks held up his sword threateningly and Goku nodded and simply raised one finger in front of him as Trunks charged, slicing his sword with almost invisible speed. Goku parried each blow with that lone finger, not even getting a scratch from the blade. He slightly turned his head, easily blocking the supercharged punch of Ki that Kagome had thrown at him without warning all while as Trunks kept up his swift strikes

Trunks released his Super Saiyan mode, looking quite satisfied, "Just as I thought. The stories were true. No, you're even better!"

"Which means we can trust you completely! And we'll tell you everything now," Kagome looked serious to Goku, "But, please do not tell anyone else what you will hear here."

"Okay! Feel at ease to tell me anything! I won't say a word!" Goku nodded.

"This might sound a bit unbelievable to you in this era, but we've travelled back from nearly twenty years in the future in a time machine." Trunks stated, much to Goku's shock.

"From the future? Twenty years?" Goku blinked, looking completely taken back at the information.

"Yes. My name is Trunks and this is Kagome. If you are wondering how we could have Saiyan blood, the reason is that we are the children of Vegeta-san over there."

Goku almost fell to the ground in shock, "Are you really Vegeta's children?" He blinked, observing them carefully, "But now that I look at you, there's a big resemblance!" Goku quickly glanced back to Vegeta, "So, he's really your Pop, huh?"

"We'll be born in three years from now." Kagome supplied helpfully.

"But, we didn't travel back in time just to tell you that. Son-san, there are very important things I must make you aware of," Trunks frowned deeply, "In roughly three years from now, on May 12, at around 10 a.m., on an island located nine kilometres southwest of Metro South, a terrifying pair of villains will appear. They will be monsters, both possessing an incredible amount of Ki."

"What are they? Aliens?" Goku asked.

"No. They were born of Earth. They are Artificial Humans, sometimes called Androids. They were created by a maniacal scientist, formerly of the Red Ribbon Army, named Doctor Gero." Kagome said, watching as Goku took a few steps back in shock.

"R-Red Ribbon Army? You mean the same one I wiped out as a kid?" Goku looked rather surprised.

"Yes, you wiped out the Army, but Doctor Gero survived, and continued on with his research." Trunks added stoically.

"Why would he do that for? Is he after world domination?" Goku asked.

"No one really knows, but we are assuming that is what Doctor Gero was after. But those Artificial Humans were built to be the ultimate killing machine, so they even killed their own creator, Doctor Gero," Kagome sighed, her normally bright blue eyes seemed to dull as she thought of her era, "In short, all that remained were the Androids, who liked nothing better than to cause death and destruction."

Goku narrowed his eyes, "Two Super Saiyans who could defeat Frieza in a second is calling them monsters, it must mean that they are pretty tough."

"You wouldn't believe it," Kagome sighed again, "We've stood up to them, but one-on-one, all can manage to do is escape."

"There's two?" Goku asked, "Don't you have any allies?"

"No," Trunks stared coldly at the ground, "Twenty years from now, we are the only warriors left alive. In the battle three years from now, our father Vegeta, Krillin-san, Yamcha-san, Piccolo-san, Tien-san, and Chiaotzu-san were all killed. Son Gohan-san was barely able to escape, so he served as our master, and taught us everything that we know," Trunks shook with anger, "Up until four years ago, when he, too, was..."

"I'm sure that you know this, but without Piccolo-san, the Dragon Balls also disappear, so we weren't able to bring anyone back to life," Kagome clenched her fists, "They're too strong! They're just too strong!" Her anger slightly faded when Trunks put a soothing hand on her shoulder.

"What about me? What happens to me? Am I killed, too?" Goku asked quickly.

"You won't even fight," Trunks said lowly, "In a very short time, you will become very sick. And soon, you will pass away. It will be a viral infection of your heart. Not even a Saiyan can fight off this illness."

"And a Senzu Bean won't do anything?" Goku clenched his fists, "What a ripoff! I wanted to fight them, too!"

Kagome blinked, "You're not afraid?" She tilted her head confusedly.

"Sure, I'm afraid, but these guys are incredibly strong, right? I would like to give them a shot!" Goku quickly replied.

"Wow, you're the perfect Saiyan warrior! You are exactly how Mother and Gohan-sensei described you!" Kagome eagerly said, looking at Goku with awe.

"When your symptoms first appear, take this," Trunks took something from his jacket pocket and handed it over to Goku, "It's medicine for you. There is no treatment for the illness in this era, but twenty years from now, we have a cure. That medicine will keep you alive through it."

"You mean it? All right!" Goku grinned brightly, "You should have told me earlier!"

"It does change history," Kagome sighed, "But the history that we will be changing..."

"I believe that you will be able to do something about this, Son-san," Trunks added, "Our Mother believes so too, which is why she struggled to built the time machine!"

Goku twitched, "Hold on! She built a time machine? Don't tell me your Mother is..." The name couldn't even come out of his mouth.

"Yes, she's right over there!" Kagome smiled, gesturing to the blue-haired woman who Goku was more than familiar with.

"BULMA?" He fell to the ground in surprise, "I would have thought Bulma would have gone with Yamcha, but she goes to Vegeta instead?" He scratched his head in thought, "This is the biggest surprise out of them all, I think!"

"Yamcha was a playboy, so Mother dumped his ass and they split up. I think that Vegeta was feeling all alone, so in one night of heated passion, we were conceived!" Kagome said cheerfully, not noticing how Trunks looked very embarrassed by her words, "They're not mates or anything. Mother's just like that." Kagome shrugged.

"Sounds just like her." Goku still looked very shocked at the news that Bulma was their future mother.

"Father died before we even really knew him, so it's really exciting to see him now! But, he seems like a bit of a jerk..." Kagome muttered the last part and Goku simply laughed warmly in response.

"Now, make sure that you keep this matter especially secret, all right?" Trunks quickly interrupted, "If you tell them and they begin to develop bad feelings between each other, and our very existence will be erased!"

"Yeah, don't worry! A word won't leave my lips!" Goku immediately relieved their concerns.

"Thank you so much, Goku-san!" Kagome eagerly grasped his hand, squeezing it, "It was so exciting to finally meet you! Gohan-sensei was right, you really are kind!" Her smile brightened when Goku squeezed her hands back before she released him.

"We must excuse ourselves. We have to return to the future and reassure our Mother as soon as possible." Trunks bowed politely.

"Yeah, tell your Mom I said thanks for saving my life!" Goku squeezed the bottle of medicine tightly, "Will we meet again?"

"I'm not sure. It takes a very long time to gather enough energy necessary for the time machine to make a round trip," Trunks said, "But if we survive that long, then we will definitely be back to help as much as we can."

"In three years!" Kagome added, "You'll see us again in three years!"

"Make sure you survive. I'll be training hard these next three years." Goku said, his first words almost a demand.

The two Briefs' nodded, taking off with a final farewell. Goku watched them go with a smirk, very confident that the two would survive.

"Now, how to explain this to everyone..."

"Ne, Nii-san?" Kagome asked, making herself comfy in Trunks' lap because there was barely enough room in the time machine for them both. He glanced down at her questioningly, silently prodding her to ask the question, "Do you think that Father will survive? I really wanted to speak with him and stuff..."

Trunks smiled, seeing the small light blush on Kagome's face, "I'm sure he will. Mother said that he was proud, strong, stern, and lonesome. I doubt he'll die this time around." He comforted, stiffening when Kagome wrapped her arms around his neck, pushing her breasts into his chest unknowingly.

"I really hope you're right, Nii-san..." Kagome muttered into his neck, pressing her lips against his skin, "I'm willing to forget about 'this' if the future changes for the better."

Trunks said nothing, pressing the button to take them back to the future.

As much as he hated to admit it, but Kagome was right, if the future was changed, then they had no reason to continue on with their relationship.

He dreaded that day...
