I don't own Dragon Ball Z or Harry Potter

Ok so Gohan killed Kid Buu, Good Buu is now a Z fighter. Kid Buu was defeated right after he was released, so the humans don't know anything about Buu.

This story takes place right after Umbridge''s speech. You will notice that some of the lines are directly copied from the Book

The Wizard World?

"-and pruning wherever we find practices that ought to be prohibited" Umbridge finished with a small giggle

She sat down. Dumbledore clapped. The staff followed his lead, though Harry noticed that several of them brought their hands together only once or twice before stopping. A few students joined in, but most had been taken unawares by the end of the speech, not having listened to more than a few words of it, and before they could start applauding properly, Dumbledore had stood up again.

"Thank you very much, Professor Umbridge, that was most illuminating" he said, bowing to her "Now, as I was saying, Quidditch tryouts will be held ..."

'"Yes, it certainly was illuminating" Hermione said in a low voice

"You're not telling me you enjoyed it?" Ron said, turning towards Hermione "That was about the dullest speech I've ever heard, and I grew up with Percy"

"I said illuminating, not enjoyable" Hermione said "It explained a lot"

"Did it?" Harry said surprised "Sounded like a load of waffle to me"

"There was some important stuff hidden in the waffle" Hermione said grimly.

"Was there?" Ron asked blankly.

"How about: 'progress for progress's sake must be discouraged'? How about: 'pruning wherever we find practices that ought to be prohibited'?"

"Well, what does that mean?" Ron asked impatiently.

"I'll tell you what it means" Hermione said through gritted teeth "It means the Ministry's interfering at Hogwarts"

"What does the Ministry want to interfere at Hogwarts?" Ron asked puzzled "Hogwarts is only a school"

"Well-" Hermione started to explain but before she could say anything the Great Hall's door was pushed open. And two boys rushed in looking around. One of them had lavender hair and bright blue eyes; he was wearing a green gi with matching orange belt and wrist bands. The other had spiky black hair and onyx eyes; he was wearing an orange gi with matching blue belt and a blue long sleeve shirt.

"Hurry up! Gohan! Videl!" One of the children shouted

"Coming" Two different voices shouted. A few seconds' two teenagers holding hands entered the Great Hall. The boy had spiky black hair and onyx eyes; he was wearing a blue gi that showed his muscular arms and chest with matching red belt and wrist bands. The girl had short black hair and ocean blue eyes; she was wearing white pants, a blue long sleeve shirt and a yellow shirt with the word 'Fight' across it.

"Now, let's see what the radar says" Gohan said taking out an oval device with a button on top, and pressed the button

"Hem, hem" Umbridge cleared her throat, trying to get the new comers' attention. But they didn't even acknowledge her. "Hem, hem" Umbridge tried again a bit irritated at being ignored

"What's wrong with this thing?" Gohan asked himself a bit confused and irritated

"Excused me" Umbridge said as she started to walk toward the small group, with the rest of the staff following "Can you tell us what you are doing trespassing-?" But she was cut off by Videl

"What do you mean? Gohan" Videl asked confused. Goten and Trunks were looking around the ruins for something that may catch their attention

"The radar isn't working" Gohan said pressing the button again but getting the same result. Videl pressed the button of her communicator but it won't turn on "My communicator isn't working either"

"It seems like there is something in this ruins that won't allow electricity to work" Gohan deduced

Everyone gasped when they heard the word 'ruins'. So that means that these persons were muggles, since the muggle repealing charm make the muggles see nothing but ruins, but muggles normally didn't get any close to the castle since it was said that to muggles it looked like it would collapse any second. Umbridge eyes narrowed and she raised her wand and threw a stunner to Gohan. The stunner hit Gohan straight in the chest but to everyone's surprise it didn't do anything, didn't even gained Gohan's attention.

"What now?" Videl asked crossing her arms, not aware of the treat close by

"Well, you guys can use a dragon ball and use it to locate the other while I try to repair the dragon radar" Gohan said taking out a capsule, he pressed the button and dropped it in front, after the small cloud cleared out everyone could see table with various tools. Gohan then took out another capsule, pressed the button and let it fall next to him; it revealed 6 orange crystalline spheres that every 5 second glowed.

"Goten, Trunks" Gohan shouted. They were on the other side of the Great Hall but to everyone's shock the second Gohan called them they were by his side "Take a ball and go look around this ruins, you already know that the ball will start glowing once you get closer to another dragon ball"

"Alright" Goten said excited taking one of the dragon balls and ran out of the hall

"HEY" Trunks shouted running after him "Wait for me"

Gohan smiled in amusement at his brother and Trunks, who he considerate a brother since he had known him all his life.

"Please, make sure they don't accidently'" Gohan said making air quotes "finish destroying this place and have my mother and Bulma yell at me how I always let my brother and Trunks lose" Gohan finished with a shiver at the thought of the last time they chattered him.

Videl giggle at the mental image of Chichi and Bulma intimidating Gohan. She hugged him and then kissed him. 'Aw' many of the girls sighed at the sight. Videl turned to leave but Gohan turned her around and gave her another kiss.

"Videl?" Gohan asked innocently

"Yes?" Videl said a bit suspicious

"Can I borrow your communicator?" Gohan asked making puppy dog eyes

"Why?" Videl asked already taking her watch off

"Well, the only electric devise I have is the dragon radar and I won't want to directly experiment with it and risk breaking it" Gohan said scratching the back of his neck. Umbridge tried another set of spells but none of those spells seems to affect or get Gohan's attention

"You are a scientist and inventor. You could give Bulma a run for her money. My watch is one of your inventions and you don't have one?" Videl said shaking her head. Many of the muggle burns and half-bloods that were acquainted with the Capsule Corporation's owners and products stared at Gohan in shock.

"Why would I want to use a communicator?" Gohan asked "When I can just communicate telepathically with whoever I want to?"

This shocked the same muggles raised since the word was not something that any of the pure-bloods were familiar with.

"Well, I don't think Erasa or Sharpener would take that well" Videl said smirking at the mental image of their friends freaking out if Gohan ever talk to them telepathically. Gohan couldn't help but chuckle picturing the same thing. Videl gave Gohan her watch and said "If you break it, you better replace it" and left. Once she left Gohan capsule the dragon balls again to make it easier for them to find the dragon ball. Gohan got to work on fixing the watch and radar.

"Don't just stand there do something" Umbridge shouted at the school staff and raised her wand again, but none of the teachers aided her. Dumbledore only stood surprised and a bit amused at the fact that Umbridge couldn't harm the muggle. He wanted so much to know who this group was and what exactly was the 'dragon balls'. The students were discussing since the muggle couldn't heard them

"I know that product" a Ravenclaw girl said "It's high on demand right now"

"What does it do?" a pure-bloods asked

"It allows the muggles to communicate by pressing a button and mentioning the name of the person they want to talk to" She said with a smile "But the best part is that you can see the person you are talking to"

And many similar conversations were going on around the Great Hall.

"Hermione, have you seen him in the news?" Harry asked while he tried to recall if on one of the times that he happened to heard the news the name 'Gohan' was mentioned

"I don't think so" Hermione said "They did mention that the creator of the communicator –watch wanted for the moment remind anonymous, I think he created many other things"

"What do you think they are doing here?" Ron asked while he watched Gohan work on the watch

"Weren't you listening to their conversation?" Hermione snapped

"They are looking for a 'dragon ball'" Harry aided Ron before they started a fight "Whatever that is" He said as he turned toward Hermione expecting to get a whole lecture about the 'dragon balls'

"What?" Hermione said as she noticed Harry's look

"Aren't you going to tell us what the 'dragon balls' are?" Harry asked

"I don't know" Hermione said a bit irritated

"Oh" Harry said surprised

"Look" Ron said getting his two friends to look back toward Gohan

Gohan had his hand raised with the index finger out and then a small ball started to form, it glowed and everyone could see an electric current surrounding it. He then put that small ball inside the watch.

"Let's hope this works" Gohan said a bit nervous. He pressed the button and said "call Bulma Brief"

No one could see if it worked since Gohan wasn't close to any of the wizards

"Hi! Gohan!" A feminine voice said "How are you guys doing?"

"Great thanks Bulma" Gohan said smiling

"How are thing back home?" Gohan asked a bit worry now, he did left Bulma doing all the work on a project they were working together

"Don't worry, everything is fine" Bulma said "Once you get back we can start in another project since I already finished with the one we were working together, thanks to the notes you left me" Bulma said

"I'm glad you didn't have any problems" Gohan said "Well, Bulma I got to go. See you next week." Gohan said

"Ok Gohan and please try to stay out of troubles" Bulma said teasingly and cut off the communication

Now that he knew how much energy was necessary to make the radar work Gohan got to work on that.

Everyone was surprised; this muggle could make energy come out of his hand! Umbridge created a patronus and send it to the ministry for back up, this muggle needed to be stopped and questioned about the thing he could do and his immunity to magic. Gohan did the same thing with the radar and was about to call the chibis and Videl when they entered.

"Gohan the dragon ball seems to be in this room" Videl said once she realized that the dragon balls were in the capsule and their dragon ball was still glowing

"I was about to call you guys" Gohan said "I just finished fixing the radar"

"Alright" Goten and Trunks said excited. Gohan pressed the button and the radar started to make a beating sound.

"Yes, the dragon ball is in this room" Gohan said excited. Everyone was looking around for a glowing ball but they couldn't find it

"Now where could it be" Gohan said as he looked around. He looked up and there it was! Right on top of him, it seems that it was between craters. These ruins sure would have been dangerous for an average person!

"There it is!" Gohan said almost jumping in excitement, pointing to the ceiling

The students looked up but they only saw the starts

"It must be covered by the charms that make the ceiling look like the sky outside" Hermione said

"And how is he going to get it?" Harry asked himself in a low voice

Everyone's eyes almost popped out when Gohan started to float. The aurors that just arrived, when they saw Gohan floating they fired stunners but they didn't affected Gohan. Gohan took the ball from the small crater it was stuck on.

"Now we can summon the eternal dragon" Gohan said as he landed. Hermione gasped loudly when she heard that. Everyone turned toward Hermione when they heard her gasp; suspecting that she already knew what was going on.

"Miss Granger?" Dumbledore asked waking toward her. "Do you know what's going on?"

"I'm not sure" Hermione said keeping her eyes on the small group

"Can you tell us what you think is going on?" Dumbledore asked

"Well, Professor. According to a muggle myth, the eternal dragon is the 'Dragon God'" Hermione a bit unsure of her conclusion.

"Please go on Miss Granger" Professor McGonagall said.

"Well, a few year before I came to Howards in my school we talked about the magical creatures that fascinated us and one of my classmates was really into dragons and I kind of got curious and started to do my own research" Hermione said, her cheeks blushed a bit "I read a book that contained the myth that there was an Eternal Dragon or 'Dragon God' that could grant you a wish if you ever encounter him, but the book never said how to find him"

"That's non-sense" Dolores Umbridge said "The Ministry of Magic keeps record of every magical creature and there is nothing about a dragon that could grant wished"

"Gohan, you never told me what kind of wishes Shenlong can grant" Videl said crossing her arms. Everyone was eager to hear what wished could grant 'Shenlong'.

"Well, the only things he can't grant are killing someone; he can't bring back to live a person that die-"

Many persons were disappointed when they heard that, so that dragon wasn't better than any wizard or witch. Everyone started to turn out Gohan

"-of old age, sickness or any others natural death"

You can bring back to live a person that was killed less than a year ago". Those words caught everyone's attention.

"Can we summon Shenlong now?" Goten and Trunks asked excited, not haven't seeing Shenlong before.

"Sure" Gohan said, he capsule his working table. They started to walk toward the exit. Umbridge wasn't about to let this intruders and possibly threat to the Ministry get away, she waved her wand and the door closed, making them jump and stare surprised at the door. Then the chibis started to jump in excitement. Everyone was surprised by the chibis' reaction.

"Cool! Do that again, Gohan!" The chibis shouted excited.

"It wasn't me" Gohan said looking around.

"You say that the other time you were playing a prank on us" The chibis said.

"But this time it really isn't me" Gohan said a bit irritated. The chibis nodded and went to open the door but Umbridge closed the door again.

"Do you think this castle maybe hunted?" Goten asked a bit excited

"Ghosts don't exist" Trunks said crossing his arm. Every ghost on the room looked offended but stayed were they were.

"They do exist" Goten said

"No they don't" Trunks said

"Yes they do" Goten yelled.

"Alright guys. That's enough" Gohan said before they started to fight "Trunks when you fuse with Goten, you guys use a technique called the 'Super Ghost Kamikaze Attack' so please don't tell me you don't believe in ghost" Trunks only hung his head in defeat

"Besides don't you guys fell like someone is watching you? And I do feel many presences here but it's different that you" Gohan said and winked at Videl, who pressed a button on her watch

"Now that you mention it the moment that we stepped inside this room I felt like I was being watched" Videl said a bit worried

"We need to capture them and bring them to the Ministry for questioning" Umbridge told the Aurors. Everyone was worried. This muggles claimed that they could 'feel their presence'

"Now what?" Videl asked "What to do since the ghost don't want us to leave?"

"They can't keep us here" Trunks said making a fist. "We are warriors and we fear nothing"

"Yeah, we will kick they butt" Goten said

"Goten! You can't kick a ghost butt" Trunks said slapping the back of his friend's head "They are intangible"

"Ouch" Goten said nursing his head "Ah… Yeah, I forgot". Gohan, Videl, and Trunks sweat dropped.

"Anyway" Gohan said looking around

"Is anyone here?" Gohan shouted "Is anyone here?" Gohan shouted again. Suddenly there was the sound of something hitting the ground, Goten and Trunks yelp and hid behind Gohan and Videl.

Everyone was amused by the reactions this muggles were having. Umbridge and the Aurors were confused since they weren't doing that.

"We only want to leave and we will never come here again" Gohan said a bit nervous. He suddenly was shoved by a strong wind. The dust started taking the shape of a man

Everyone gasped. The staff was looking around but none of the students had their wand raised. Who was that men? The Aurors firer spell but they just passed through the dust without affecting it. Students begin to panic thinking that it was an evil spirit, some ghost were known to have special abilities

Videl got into fighting stance but she too was shoved aside by the wind. Goten and Trunks were frozen in their spot. They could only stare at the ghost in front of them. The ghost started approaching the chibis he extended his hands toward the chibis, they closed their eyes and-

"Bu" The chibis screamed and ran out of the Great Hall, going through the door leaving chibis' shape holes. Everyone stared shocked at the holes the boys left. Two laughers snapped them out of their shock. Gohan and Videl were rolling in the ground laughing and holding their sides.

"Please… Te-… Tell me… You got it… recorded" Gohan said between laughs. Videl only nodded and continued laughing.

"What was that?" Ron asked in a small voice.

"I don't know" Hermione snapped looking at the pile of dust left from that dust shaped man

"How exactly did you manage that?" Videl said once she managed to control herself and stood up.

"It was pretty simple I just put together all the dust and manipulated it to form a dust shaped man" Gohan said as if it was an everyday thing. Everyone was awed by all the things this guy could do.

"Let's go and find those two and summon Shenlong" Gohan said taking Videl's hand and walked out of the Great Hall.

"It's obvious that this muggles use the wishes the dragon grant them to make themselves specials" Umbridge said. Many had to agree with her since it was the only explanation they could come up with.

"Let's follow them and get those balls so they can't make themselves more powerful" Umbridge said and followed after the muggles. The students followed despite the professors' protest. The professors followed for the student's safety.
