Here is my newest story. I wasn't sure if I should make a YYH/X-men crossover, or a YYH/IY/DBZ/X-men crossover. After thinking about it for a long time, I decided to make both, if possible! The first one, which is this one, is the YYH/IY/DBZ/X-men one. I have quite a bit in a notebook, and I have ideas for it. Any ideas I don't use in this one will be used for the YYH/X-men one. Please R&R!

The time in which this story takes place is a bit confusing, so bear with me.

YYH: After Yuske finds out his lordship ((I don't know much about that, so any details will be my way of looking at it.)) He came back from it early, sort of. He dealt with it for 2 years.

IY: They completed the jewel, but they haven't done anything to it yet, and they just sort of hang out. Inuyasha spends a lot of time in the future, which is our present, and knows quite a bit about the times. It is almost three years after the start of the show.

DBZ: Buu is defeated, and Goku is alive. Gohan is still in high school…last year. Gohan and Videl are also girlfriend and boyfriend.

X-men: As if I know a lot about that story line…just put it anywhere in there where the teachers at school are aware of the mutants, but not necessarily the students. I need help to find out some of that.

Sorry for all the skipping around, but with six new people coming to the Institute, it really can't be helped!

Chapter 1: The Letter

Feudal Japan:

"What?" a voice screamed and echoed through the vast forest.

"Inuyasha, you heard me. I got this letter, and you did too," came the much calmer voice of a teenage girl.

We meet our favorite miko and hanyou discussing two letters they just received. The problem is that no one knew that Inuyasha had been spending time at Kagome's house, so how could he get a letter? Still, it was a letter, and when they opened it, it told them to go to a shrine to have a meeting for a school. Because it would be rude to turn down such a request, they decided to go.

Modern Japan:

The blue-haired grim reaper flew down from the sky on her oar, looking for a group of people. When she found them, she yelled, "Hey, there you are, boys. I've been looking for you. Koenma wants you to head to his office immediately!"

"Why is that, Botan?" asked the boy with the long red hair.

"He didn't say, Kurama, but I'm sure that he has a reason. He wants you, Yuske, and Hiei immediately."

"Why not me?" asked the slightly stupid boy with the short orange hair in the ugliest hairstyle ((Kuwabara bashing!)).

"Because, Kuwabara, you are an idiot," said the short boy with black hair that made up for his height because it was so spiked up.

"Now, Hiei, that is no way to talk about people," said the last boy, apparently Yuske.

"Hn. Whatever you say, Lord," replied Hiei, doing a mocking bow. In order to stop the madness, Botan just opened a portal to Spirit World and ordered the boys to go through it, leaving a very confused Kuwabara.

Capsule Corp.

"I wonder what's with this letter," said a pensive Gohan.

"Oh, it must be for a school for people that are smart. I mean, you are very smart, and people are finally starting to notice," replied Bulma.

"Yeah, but then why are they waiting for my last year to ask me to go? They must want me for some other purpose."

"Well, whatever it is, you might as well go. I mean, you can get there very fast, so that is not a problem. Just go there and see what they want. Who knows, they might need you for something bigger than it looks. Besides, you mom would bug you forever if you didn't."

"Good point, Bulma. I guess I'll go. What is there to lose?"

Spirit World:

"Now, boys," said Koenma in his teenage form, "You all got letters, did you not?"

"Well, yeah," said Yuske, "But why?"

"The reason is because there is a mutant problem that is mixed with a demon problem. What you need to do is be undercover as mutants. They found you because they have a machine that can detect 'non-human' humanoid energies. They think of it as mutants, but it can also work for aliens, demons, and even the extremely powerful mikos. They found you three out because you all have some demonic energy in you. They just recently found you out for two reasons:

"One: I had the barriers around you and some others removed, so that you would be found, and

"Two: I had a small demon break into the machine and make it so that it would focus on your energies and the energy of the others I spoke about.

"That way, you could be seen for about an hour before the problem would repair itself. Any questions?"

"What kind of demons are we talking about?" asked Kurama.

"Mostly A, but I have a report of an S-class, and I don't want to take my chances. Also, I need all of you because there are many mutants on that side that are gaining power with each new day."

"What about the others you talked about? Will they help us?" asked Yuske.

"I'm pretty sure. One of them is a half alien whose dad is a close friend with my dad. He is said to be stronger than his dad. Another one is a hanyou of legends, and the last one is the time-traveling miko."

"You mean THE time-traveling miko?" asked Kurama, "I heard she was the most powerful of all mikos, and she had a hanyou friend, probably the hanyou you talk about. I wouldn't be surprised if the hanyou is at least and A-class."

"Hn. Hanyous don't become anything more than C-class, unless they are evil, so he can't be that strong."

"Hey, I'm part human and part demon, and I'm stronger than you, as well as not evil," said Yuske, trying to defend himself.

"You are also of a royal blood line, and you didn't know your demonic side until you were already strong. So, that doesn't count," said Hiei.

"Actually, the hanyou is of royal blood line. He is the son of the great Inu no Tashio," said Koenma, "So don't think that he is a weakling. He really is powerful. He and his group just recently defeated the evil Naraku."

"Naraku was a fool. He should have known that there was someone that could have beaten him. He could of at least gotten rid of that incarnation that was the reason for his demise," stated Hiei, "Even the most powerful of demons should not have a traitor on their side."

"Well, that was his way of thinking," said Koenma, "And it was a good thing, too. Had he not, we may still be battling him, or the battle would have lasted longer than it did."

"I think we are getting off topic," said Kurama, "So we should just deal with the hanyou and the miko when that time comes, but as for now, we should just deal with the thing at hand, which is the school."

"Good idea, just go home, everyone, and get your things in an area where you can pack them easily. Don't pack them, though, or else they will be suspicious," said Koenma, "Oh, I almost forgot. Yuske, you don't know English, do you?"

"What about it?" asked Yuske.

"Kurama, make Yuske a translating plant."

"Sure," replied Kurama as he made the plant and put it behind his friend's ear. It locked into place, and it wasn't noticeable, unless you were looking for it.

"Oh, and Hiei, I have a special job for you," said Koenma.

"What is it?" he asked.

"I need you to make a barrier around everybody's minds. The mutants can do things like read minds, and I don't want to take any chances."

"Hn. Whatever."

"Thank you, Hiei, and good luck, everybody."

The Reikai Tantei left the room, all going to their respective homes to get their things in order.

END CHAPTER

How was it? Too much dialogue? Too little descriptions? The worst story you have ever read?

Anyway, I would like to give the pairings, at least for the beginning of the story. They are subject to change, but I know it won't be a Kurama/Kagome pairing because I have Inuyasha in the story, and that wouldn't be a pretty sight. Though, I do like that pairing.

Inuyasha/Kagome

Yuske/Keiko ((this one subject to change))

Kurama/Botan ((this one subject to change, but not likely))

Hiei/Rouge ((What? They make the perfect couple?))

Gohan/Videl

Logan/Storm ((hinted at, a little))

The pairings are not all final, but they are an idea. Also, this story is T for Teen, meaning NO LEMONS! First of all, I am underage for reading those, so I don't want to write them…they are disgusting, at least in my mind. If I am reading a story with one in it, I just skip it.

Also, there is no yaoi in this story. I don't think it is right. NO EXCEPTIONS!

Also, this is going to be a long story, so just sit back, and let me type. I have a few other stories going, and they take up quite a bit of my time. Sorry if I don't update for a while.

Review/email ((if you know it…)) me any ideas. I have a notebook that goes up to them getting to the Institute, but I have already changed a lot since the notebook has been written.
