Disclaimer: If Yu Yu Hakusho and Harry Potter are owned by Yoshihiro Togashi and JK Rowling (respectively), then I do not own either works. You purple people people should feel special, I'm updating this one more than usual because I'm bored of the others.

Now, both Hiei and Snape, and just around everyone, are probably OOC. Well, maybe they aren't, but I can't help it! I'm paranoid about these things! No, really I am! But, I know for sure that Snape is OOC. It can be argued that the unusual circumstances caused Snape to throw a fit, but he's still OOC

Chapter Three

"So, you're a spy." It wasn't a question.

"Yes, I am. I chose you because, from what I've seen, you're the only one with the tact and personality to pull it off."

"Hn, Shuichi is just as capable of being you."

"Shuichi has all the knowledge needed to switch with Ms. Granger." Snape was obviously referring to the fact that Shuichi was related to a wizard working at Hogwarts.

Hiei looked at Snape in skeptical thoughtfulness. "You're mind is set on my taking your place."

"It is."

"Fine, at least you aren't a red-headed idiot with freckles."

Time Transition

"So, what's Snape the god of?" Ron asked Hiei eagerly. Snape bent down and whispered something in Koenma's ear, which caused Koenma's face to pale. Meanwhile, Hiei glared at Ron.

"I'm sorry, but Hiei cannot divulge that highly personal information," Koenma stated matter-of-factly. George attempted to place, discreetly, three goblets on Koenma's desk. He would've failed in this task if not for the small drama unfolding.

"What?! Why not?!" Ron shrieked, looking outraged. Harry sighed heavily, and Hermione looked ready to whack Ron upside the head. Both were muttering about respecting deities.

"We're on the same side, we deserve to know!" Kuwabara yelled to the whole room, crossing his arms with a disturbing pout upon his face.

"Incredible, was that actually a semi-intelligent remark?" Hiei asked. The Golden Trio, or rather Harry and Hermione because Ron was bristling at the remark that he thought was aimed at him, were unable to directly pinpoint whether or not he was being sarcastic.

Kuwabara and Ron glared. Hiei and Snape glared right back. Before the staring contest could escalate, they were interrupted by Koenma stating that they should get ready for the transition.

"Wait, how are we going to switch? I mean, my hair isn't exactly red," Yusuke asked. No one had a response to that, except Koenma.

"Polyjuice Potion, of course."

"Oh, yeah, of course." Yusuke and Kuwabara stared at each other blankly, then chorused in unison, "What?!"

"It's a potion that allows its drinker to turn into anyone they wish," Hiei stated, irritation evident in his tone. "There are other details, but they are unimportant. It isn't as if you two could successfully brew one."1

"Hey! Stop knocking my intelligence! I bet I could too brew one!" Kuwabara yelled.

"Stop it, both of you. Hiei, you know that Kuwabara couldn't brew it, he doesn't have the necessary ingredients. Kuwabara, perhaps if you stop reacting so violently to Hiei's insults, he wouldn't bait you as often," Kurama commanded, softly but firmly.

"Oh, I bet he would too. He doesn't have a life, so..." Kuwabara's insult was ended by Snape's shout.

"Enough! We haven't the time to waste with your arguments! We have to drill you on what habits the people your switching with have, and on the Polyjuice Potion! We only have one and a half days left, we don't have anymore time for meaningless interruptions!"

"Umm, sir, we only have one and a half days left if we discount sleeping," Harry stated uncertainly, his hand half raised above his head.

Snape's eye starting twitching. "The fate of the Wizarding World lies, partly, in your hands and you want to waste possible preparation time sleeping?!"

"Yes," Yusuke said, with a cocky smirk on his face.

Snape looked murderous. He stalked over to Koenma's desk and slammed down a liter2 of a mud-like substance that the Golden Trio recognized as Polyjuice Potion. He then left the room, or attempted to. He found Kurama blocking the doorway.

"Move," Snape hissed through clenched teeth.

"No, I don't believe I will, Professor. You, see," Kurama completely disregarded the fact that Snape was glaring murderously, and that the potted plant next to him was starting to quiver, "we don't know the how much of this Potion to consume."

"Why don't you ask Potter, I'm sure he's brewed this particular potion before," Snape snarled. Ron made a rude hand gesture behind Snape's back.

"But sir, I believe you should stay anyway. From what I've heard, you don't believe Harry to be competent in regard to Potions." The plant stopped quivering.

Snape stared at Kurama for a while, then stalked back over to Koenma's desk. "Mr. Minamino, Mr. Urameshi, Mr. ...Hiei, form a line on the right. Ms. Granger, Mr. Weasley, form a line on the left."

Ron looked at Hermione oddly. He was wondering why Snape had told them to form a line. There was only two people. Pretty hard for two people to form a line.

Snape poured in ¾ of a cup of Polyjuice Potion into a goblet. He then held out his hand in Ron's direction. Ron reluctantly pulled out a strand of his hair, and handed it to Snape, who added it to the Potion.

"Eugh, we have to drink that?!" Yusuke asked, sounding disgusted. "It looks like crap!" Kuwabara laughed at the three in the background. "Shut up, before I pound your face in, you..." Yusuke was cut off, as something that tasted like overcooked cabbage and felt like toxic mud was forced down his throat. What followed felt like a mini-version of Genkai's final test when the Dark Tournament was nearing it's end.

"What the hell was that for?!" Yusuke asked, glaring at Snape, then looked shocked down at his hands when he realized that his voice sounded different.3

"Well, it seems that forcing unpalatable concoctions down a persons throat saves me the time of have to use a cleaning charm on student's mouths," Snape stated with an evil smirk and a delighted look upon his face.

"Who cares?!?! What the hell happened to me?!" Yusuke yelled. Although, he didn't look or sound like Yusuke Urameshi anymore. Now he looked and sounded like one Ronald Weasley.

A/N: I started this chapter weeks ago. Finally finished it too. Whatever.

1. I know I said before that Kurama didn't know Western Magic (and yes, his grandfather is a teacher there, so why he doesn't know Western Magic will be explained at a later date), so why does Hiei know about the Polyjuice Potion? Potions are universal (just under different names)and, in some cases, interdimensional, at least in my fic.

2. I don't know how Snape got his hands on it, but the Polyjuice Potion was carried in a plastic soda bottle.

3. Yes, it's still the Polyjuice Potion. It'll be explained next chapter.

Thanks to everyone who reviewed:

mangamaniac135:

I'm glad you enjoyed it. And I think the grammer and spelling you're refering to was done on purpose. But thanks for informing me. Now I can go back and look for errors.

kit-kit:

Oh, wow. Thanks! ::grins happily:: I tried to make it original. I mean, the plot isn't, but some of the details are original. I'll give you a hint about Snape. (Well, really, to anyone who decided to read this) Snape is the offspring of two Greek deities.

Talon and Skittles:

Thank you. I was aiming for it to be funny, but I wasn't sure that it contained enough humor for it to be listed under the humor section. And it is continued.

HarmonyHanyou:

I'm glad you enjoyed it. Their antics seemed a bit rushed to me, but whatever.

Icy Tears:

It's being updated more often now. I'm glad.

Kat1132:

Yep, that's what I'm doing. Glad you thought it was a good idea. Making it so that the YYH people had to keep it a secret at Hogwarts would've distracted them from their mission. That, and it would've been harder to juggle. Don't worry, I've written reviews that were mini-essays.

R&R!
