AN: I would like to say thank you everyone for your reviews and critics. I really appreciate it. Now to answer most of the reviews' question, yes I know the way I divided the Kais are not the same as the ones in Dragon Ball. I think I did mentioned in the beginning of the chapter that I will not follow Dragon Ball and Harry Potter exactly. Let's just say for the purpose of this story, Northern Kai will be ruling where Goku and the gang are and Western Kai is the Great Britain side. Again, I'm catering this story to Harry Potter fans more than Dragon Ball fans, so I'm tweaking the Dragon Ball information so it's easier for the Harry Potter fans to follow. Hope you enjoy this new chapter, cheers!

The ride home was fairly quiet for the Briefs and Bulma found it disturbing because usually someone would quarrel over something or steal something or poked something. From her review mirror, Bulma glanced at her only daughter, Kira Bula Brief, who was occupying herself with her iPhone.

Flashback

While the men were surrounding the grill, the women were sitting on the porch, enjoying their margarita except for Leah.

"This is highly unusual for you to turn down a drink… Unless…" Bulma gasped and looked at Leah who just smiled at her.

"Yeah, we're expecting another one soon." Leah answered.

"Oh that is great! Are you going to find out the gender this time? Oh wait, it's Krillin we're talking about here, of course not, he and his surprises." Chi Chi rolled her eyes.

"Well Krillin can stay in oblivion like he did with Luka. I've always known Luka would be a boy." Leah sniggered.

"You sly! So go on, tell us then!" Bulma whispered excitedly.

"I'm having a girl!" Leah whispered beamingly.

"Aww congratulations honey! Gosh, I've always wanted a girl. Stupid Saiyan and their male dominating gene!" Chi Chi complained.

"Wait, how did you managed to get Kira, Bulma? Vegeta is a Saiyan just like Goku!" Chi Chi recalled.

"Well I did play dirty actually. As soon as I found out I was having another baby, I immediately worked on separating Vegeta's Y chromosomes and…"

"Wait wait wait… You can do that?" Chi Chi asked in surprised.

"Honey with science, almost anything is possible." Bulma winked as she drank her margarita.

"But I have some regrets though… I pity Kira… She has no girl companions and Videl is a sweetie but let's face it, she's older than Kira. Vegeta is so protective over her that most kids in the school are too scared to befriend with her." Bulma sighed.

"Maybe you should send her to an all girls boarding school." Leah suggested.

"Hmm… I could try that. I'm sure Kira would agree… The only problem is convincing her stubborn ass father." Bulma rolled her eyes and the women laughed.

Flashback ended

Bulma's attention reverted back to reality and continued to focus on driving. She sighed silently to herself, feeling rather irritated that her Saiyan husband refused to take driving license. His refusal of course happened when he had witnessed Picollo and Goku's attempt to take the driving license.

Bulma remembered their argument regarding this matter and in the end she finally complied to his wish when he literally drove her sweet Mercedes XLR right into the walls of their house. She chuckled lightly to herself and Vegeta of course caught his wife's silent laughter.

Usually he would asked her what she thought was funny but his mind was very much occupied with the new information he had received not long ago. Veins began to formed across his large forehead as his brain began to digest the information slowly and plans began to float around in his head.

Flashback

"You are very much aware that there are many types of people in this world alone." The great Northern King Kai began.

"Each universe has their own 4 sets of Kai, Northern, Southern, Western and Eastern Kais and Earth has 4 Kais as well.. Each Kais guarded their given territories and each of us keep our tongue tied about what goes on in our territories. We do know a little bit about each others' world but not very much. I cannot tell you in great details about the other world where Harry comes from which is called the Wizarding World. Only Western Kai can inform you more about it and he will when he visit me again sometime tomorrow as per my invitation. I'm truly sorry Vegeta, I know how badly you want to know but I'm afraid you will have to wait for a little while longer."

"Great! This is just great! More waiting. That's hardly informative at all!" Vegeta threw his hands up in frustration.

"Be patience Vegeta. You should be thankful because at least now you know where Harry comes from." Goku put his hand on Vegeta's shoulder and his normal lighted voice was changed into deep and serious when Vegeta was starting to disrespect the King Kai whom Goku very much respected.

"Fine. I will wait. When are we meeting with this James Potter?" Vegeta just shrugged off Goku's hand. He knew when not to cross the line with Goku and the line usually involved the people Goku respected.

"They will come tomorrow around noon. So I suggest Goku and the rest to go to your house tomorrow and we can discussed this further with the man himself." King Kai suggested and Goku nodded in agreement, followed by Piccolo, Krillin and Master Roshi.

"Fine… Tomorrow it is." Vegeta grunted.

"Vegeta, be careful. Now that we know something, it's best if we keep our guards up." Krillin said.

"I always have my guards up…" Vegeta smirked and walkout. He ignored the annoyed look that Krillin had on his face.

"He's still an ass even when we're trying to help him!" Vegeta heard Krillin complained and he vaguely heard what Goku replied but it sounded like Goku was defending him again, as usual.

"Father! Father! Are we leaving?" Harry said once he saw Vegeta walked into the living room where he was previously playing with Luka.

"Yes, we're leaving now. But before that, can you show me how you get these toys again?" Vegeta asked as he knelt down to Harry's level.

The boy's face began to lit up brightly like a Christmas tree and nodded his head so fast that it would fall off if he was the bobble headed toy. Harry thrust his hands onto the nearby vase and the vase transformed into a cowboy figure which Vegeta vaguely remembered seeing from one of the cartoon show during the family movie night, a tradition that Bulma started when Harry began to talk.

Vegeta tried to sense for Harry's Qi when he displayed his new power and puzzles began to loom in Vegeta's head as he couldn't sense it. Whatever power that Harry just displayed didn't show any sign of the familiar Qi that everybody in this house had. However when he was training Harry to fly before, his Qi was similar to them. More questions to be answered tomorrow.

Vegeta just ruffled Harry's head after the show of his power then got up and began to look for his wife, telling her that it was time for them to leave.

Flashback ended.

Vegeta snapped back into reality when the car stopped in front of their mansion. The Brief's family got out from their car and began to walk towards the door when Vegeta suddenly stopped his track and extended his arms, stopping the rest of the family as well.

"What's wrong dad?" Trunks asked.

Vegeta's eyes became sharp as he focused at the house. Sensing something was out of the ordinary he closed his eyes to get a better concentration.

"Vegeta! What is it? It's freaking cold to stand out here and the kids would get sick and…" Bulma was silent by Vegeta's palm that clasped her mouth.

"Be quiet woman." Vegeta hissed. Harry moved closer to Kira, gripping her t-shirt while Kira pulled him closer.

"Daddy?" Kira whispered.

Then before they knew it, a loud explosion sound erupted from inside of their house. The loud explosion shattered all the windows and smokes came out of it. The night skies suddenly became darker than it usually was and a strange symbol was formed in the sky.

"What the…" Vegeta couldn't finish his words when he was interrupted by Harry's screaming in agony. Vegeta turned around to see Harry, who was already on the ground, grabbing his head.

Bulma was already next to him, frantically looking in her handbag for something that could ease Harry's pain. Vegeta was about to move to Harry but there were movements that caught his attention. His eyes grew wide as he saw black hooded figures with masks began to materialize just like how Goku would appear whenever he used his teleportation skill.

"Trunks! Get them to the safe house NOW!" Vegeta commanded to his eldest as Bulma carried Harry and began to run away with Kira following closely behind.

"No dad! I can fight with you!" Trunks stubbornly argued and remained next to his father and transformed into Saiyan mode.

"Do NOT argue with me! Go with them NOW! Remember what we talked about!" Vegeta pushed Trunks towards Bulma.

Hot frustrated tears were lingering in Trunks eyes and reluctantly he began to run towards his mother and the rest of his siblings.

Flashback

Trunks, in his Super Saiyan mode was training in the gravity gym. His face was filled with annoyance and anger so his brows were filled with popping veins. He did pull ups while the gravity was at 40 kg. Normal boys would have pinned to the ground if they were in the gravity room but Trunks was not an ordinary boy. He was the son of the Prince Saiyan and he was a Saiyan as well.

However, unlike his cool demeanor father, Trunks was very much a compassionate boy like his mother. Which also meant that his behavior was the same like any other teenage boys; he was lazy to get up early on Saturday mornings for the usual long training hours with his father.

However, today was different than all the Saturday mornings that he had to get up early ever since he was 8 years old. This Saturday would be the first Saturday for Harry who would be turning 8 later this year which meant that his training with Vegeta would be starting too.

When Trunks got up that morning he was feeling rather excited. Finally his father would not focused solely on training him. He would divide his attention on training Harry as well! The would ease his normally rigid, worst than military training. Imagined Trunks' disappointment when he arrived in the training room only to see his father there and his adopted younger brother was nowhere in sight.

"Where's Harry?" the young teenage boy asked his father who had already begun his warm ups.

"Still sleeping…" he replied short.

Trunks stood in the middle of the gym, wondering why the younger one was not present and was even allowed to sleep in!

"Why?" He finally mustered the courage to ask his father.

"Because he's a kid. Why the 21 questions? Start your warm up now!" Vegeta's loud voice startled Trunks and he obeyed his father, not wanting to annoy him further.

Vegeta had left the gym for awhile when Bulma called him into the house, he was not pleased at the interruption but he went in nonetheless. Trunks finally let out his frustration towards the unfairness treatment his father gave him this morning.

"It's not fair!" Trunks yelled while doing impressive air kicks and shot out powerful electric beams. While in the midst of throwing his tantrums, Trunks didn't realized that he had formed into the second level of Super Saiyan.

He continued to perform various martial arts movements that his father, Goku, Gohan and Piccolo taught him. He even added some new moves that he and Goten discovered when the two were playing their usual friendly fights. Trunks stopped in mid air when he heard clapping sounds, coming from below. He looked down and saw the man himself, Vegeta.

"Impressive… You've reached the second level of Super Saiyan mode at such a short time." Vegeta praised his eldest son whom finally landed on the ground.

"Why dad? Why do I have to get up every Saturday morning to train ever since I was EIGHT but now that Harry is the same age as I was and he is still excused? The only training you gave him is the lousy flying training! And that was like only once a week for only 2 hours!" Trunks finally burst out, couldn't bury the feelings anymore.

If Vegeta was surprised by the sudden outburst of his born, he hid it very well. His eyes just stared at the purple haired teenager.

"Because I trust you…"Trunks immediately powered down as soon as he heard his dad said the 4 words.

Question marks were written all over Trunks face which prompted Vegeta to explained more.

"You're the eldest, Trunks. You are the one that I trust to look after the family if anything were to happen to me. You are the one to protect them when I'm gone. I trust you. I trust you to make sure your mother, sister and brother safe. To take charge, to be the leader." Vegeta explained and his eyes soften a little bit as he looked at his son whom looked up as well.

"I didn't mean to put such pressure on you but I want to prepare you. The world may be seemingly peaceful now but never take that for granted. Call it a warrior instinct, I feel that something big will happen sometime in the near future. Your brother, Harry.. He is strong, but his strength is something that I'm not familiar with so it's hard to train him. I can't impose the same training that I've been giving you because it wouldn't match to his strength. I'm still trying to figure it out. I'm not playing favorites, son. You are my blood, you are my first born and I treasure you. I trust you."

Flashback ended

Trunks casted one last look at his father who was transforming before entering the safe house that his genius mother and grandfather built in case of emergencies like this. With a look that said he would honor his father, Trunks sealed the passage door of the safe house before joining the remaining of his family members.

Vegeta transformed into Super Saiyan level 2. Strong power balls began to formed on Vegeta's hand and with great focused, he threw it straight at his attackers. The attackers drew out sticks which later Vegeta remembered it being termed as 'wands'. Some of the attackers were slow in reaction and they were hurt by Vegeta's power ball but the remaining ones managed to deflect it.

Vegeta's warrior brain automatically began to categorize his attackers by level of hierarchy. He was about to form more power balls to attack the group that he categorized as pawns but the group that he called the knights were shooting out some sickly red colored beams from the tip of their wands.

"CRUCIO!"

"BOMBARDA!"

"IMMOBULUS!" shouted the attackers.

Vegeta may had no clue what those attacks were but he was smart enough to know that he needed to avoid all of it. Being trained under thousand tons of gravity weigh definitely had its advantages as Vegeta avoided the curses with ease.

"Is that all you got bastards?" Vegeta smirked. The attackers seemed to be in temporarily shock at the man in front of them who just avoided three simultaneous attack with the speed of lightning.

When they realized they were being insulted, they continued with their attacks. Vegeta formed powerful Kienzans, destructo discs, and blasted the 'pawns' who dropped dead and barbequed on the ground.

"What are you waiting for? ATTACK HIM IMBECILES!" One of the masked figure shouted to the men in front of him. Vegeta categorized him as the leader of the pathetic groups that were attacking his home. Pathetic indeed because he was remaining at the back of the lines of men.

Realizing that their source of weapon was the wands, Vegeta changed his form of attack. He appeared in front one of his attackers, shocking him in the process and slashed the arm that was holding the wand with Vegeta's bare hand. The attacker screamed in agony and fell to the ground, holding his now mutilated hand.

Vegeta's killer instinct never left so he finished the fella with one strong stomped right into the poor guy's skull. More men surrounded Vegeta and they began firing curses in what Vegeta claimed to be idiotic words. Vegeta flew up high to the sky and he was expecting them to follow him but he was surprised to see that they remained on the ground.

"They can't fly? Oh this is just so easy!" Vegeta said to himself with full arrogance.

"AVADA KEDAVRA!" green beam was shot straight at Vegeta's direction. Not anticipating this attack to be faster than the previous attacks, Vegeta's eyes grew larger when the beam was closing on him before he could move.

Right when the beam was just about to hit him, Vegeta felt something grasped his shoulder and before he could identify the intruder, he reappeared back to the ground.

"Kakarot" Vegeta answered himself as Goku materialized next to him followed by Piccolo, Krillin and Master Roshi.

"How do you know?" Vegeta asked as all of them began to open their fighting stance.

"Bulma called…" Goku answered then he transformed into the same level of Super Saiyan as Vegeta.

"Kame hame ha!" Goku thrust both of his hands towards the attackers and golden beams shot out of his hands. Some were unfortunate and got hit while some were lucky enough to escape it with minor burn on their robes.

"That's the leader!" Vegeta shouted through their battle and pointed to the attacker with a different kind of mask on his face.

"Taiyo Ken!" Krillin shouted as he produced solar flare aiming to the leader that Vegeta pointed who seemed to be planning his escapes.

"Protego!" The man shouted and a shield formed in front of him, deflecting Krillin's solar flare.

"What the..." Krillin's jaw dropped when he saw the unfamiliar shield formed in front of the enemy's body. Taking advantage of Krillin's momentarily clueless expression, the said man disappeared with a 'poof' sound. Krillin smacked himself on the head, feeling silly that he had let the enemy got away.

"HIYAH!" Piccolo shouted as he used his famous tsuibi dan, an energy attack that followed wherever the victim went. The guy screamed when he couldn't outrun the power and was hit directly on his back. He fell to the ground with a thud, lifeless.

Master Roshi was gathering his energy for his Kame hame ha but before he could produce it, the attacker already readied his wand.

"AVADA KEDAVRA!" he shouted and before Master Roshi could react, the spell hit him right at his chest.

"Master Roshi!" Goku turned towards his old master who collapsed to ground. Goku glared at the attacker and screamed as his energy level increased even more.

"Kaio Ken 4!" Goku screamed out as he flew straight to the attacker in a red glow with his fist up.

The attacker shot more curses but it seemed to deflect away and before he knew it, Goku punched his stomach, hard. An ugly cracked were heard when Goku's fist made contact with the person's body and when Goku landed on the ground, the body fell next to him, lifeless.

"Retreat!" One of the hooded masked figure shouted when she realized that their leader was no longer there and the survivors disappeared just like how they appeared.

Vegeta shot out another power ball but it hit the ground where one of them had been before.

"Damn it!" Vegeta cursed.

"Master Roshi!" Krillin ran towards his old master.

"Master Roshi!" Goku shook the unmoving body of the man who taught Goku martial arts when he was younger, the man who took care of him and the man who had been through many things with him.

"Master Roshi!" Goku called his master, his teacher, his loyal friend and his grandfather figure again but the said man remained unmoved, lifeless.
