A Mugiwara Goes to Hogwarts

I know I've said it before, but I am truly sorry for not updating earlier. School has started and already I'm swamped with homework, reports and tests. Not to mention taking care of a new puppy. Anyway, hope this doesn't come out too late for everyone. Also, thanks again for all the great reviews! They really make me smile. :) Well, on to the story.

…

Harry sighed heavily as he walked down to the Great Hall. He had stayed up late the night before trying to finish the homework that wasn't done when Professor McGonagall had he, Ron, Hermione and Usopp bring Malfoy to the hospital wing. The trip had taken longer than it should have, longer than any trip to the hospital wing should have, when someone's Filibuster Fireworks went off in the hall they were walking down. It was complete chaos as the culprit, a second year Hufflepuff no less, tried to escape the scene of the crime. It had taken over an hour to track the kid down, and now Harry was exhausted. Ron and Hermione had gone to bed early, Ron saying he could miss a few assignments and Hermione that she'd already done it. Usopp, of course, didn't have homework and so Harry was left to fend for himself and hopefully pick up his less than desirable grade. He was walking past the staff room when he heard it.

"What I want to know is, is it at all likely that he's here for the tournament?" Harry could hear Professor McGonagall's voice through the crack in the door.

"It is a possibility Minerva, but the place he says he comes from makes that suggestion somewhat unlikely." Dumbledore. I bet they're talking about Ussop.

"The Grand Line, I think you said? How ridiculous. I suppose you're thinking it's another dimension or some sort of thing."

"I am not thinking it," Dumbledore laughed, "I know it. I asked Professor Binns to come down to explain it all. I hope you don't mind. Now Severus, don't look at me that way. I have not yet lost my mind. You may start, Professor Binns."

"Well," Binns' droning voice, often so completely dull it put students to sleep, sounded rather hesitant, "there is no real evidence of a world that contains an area called the Grand Line. I would normally say that it's only a story, but," here the ghost seemed to pause, "the only book with any such historical record of it is in my personal collection. A work of my father's you see… All other books, written by my father's fellows, were burned. No one in his right mind, though no one has confirmed the boy is in his right mind, would try to pass such an excuse."

Snape's sneer was easy to imagine. "I'm sure your father was a great… historian, Binns, but I was of the impression, stupid me, that historians told history. Or is the old fashion never to say a word about anything?"

Dumbledore cut in, "Ah, yes, you would think so, but this turns out to be a somewhat special case. There is not time to delve into the whole history of it, however, suffice it to say that, because of personal interest in the Grand Line the ones who discovered it, after publishing their findings in a select few books, and realizing that ridicule was the only thing that would ever come of it, burned most of the copies. They did leave behind a diary though, and my father kept one copy that is now in the restricted section of the Hogwarts Library. That book has never once been checked out… I will allow you to continue the rest, Binns?"

The old ghost's voice was as monotonous as ever. "Yes, well… on page one hundred and three the diary asserts that the 'Grand Line is a long, winding stretch of sea filled with fantastic creatures such as Sea Serpents and enormous scaled lizards. Also prevalent are people, though there seems to be no magical energy among them. The types of people are as varied as they are back in my world, but there are two select professions that these people engage in that seem the most common. The first is the law-abiding vocation of Marine. The job consists of keeping order over the vast seas of the world and the occupation seems to work very much like the British Royal Navy does. The other, however, is less tasteful. Ships full of pirates sail the waters, plundering, pillaging and causing havoc wherever they go. They also…"

Harry heard footsteps echoing down the hallway behind him. He then realized that breakfast was almost over and that the teachers would soon be coming out of the staff room. He didn't want to be caught any where near the door. Still, I learned enough. Pirates and Marines, huh? And no magic. No wonder Usopp thought that they were insane. Though, to be honest, the thought of men with beards yelling "Arr," and telling people to walk the plank in this age seems ridiculous as well.

…

Usopp's first class was to be with a Professor Moody, whom Harry and Ron called Mad-Eye. Hermione had brought Usopp some school robes that the Headmaster had given her so that he wouldn't attract unnecessary attention. He, personally, thought he looked rather stupid. It looked almost as if he was wearing a dress and Usopp knew that if Sanji or Zoro ever saw him in this garb they'd never let him forget about it. He had a brief, insane image of Sanji following him around with hearts in his eyes and asking what food was his favorite, and, blanching, he banished the picture from his mind, hopefully forever. Creepy… He tried to bring his mind around to another subject, and began thinking about what the Headmaster had said that morning at breakfast. Professor Dumbledore, as Usopp recalled, had said that Usopp was an exchange student from some country called Japan, but that he knew English, something Usopp hadn't even realized he was speaking and which was a language he had learned from his mother early on, a little while after his father had left. After his mother died he'd almost forgotten the language until he met Kaya, who at the time spoke English exclusively. Now he was so used to it he could switch languages at the drop of a hat, and as a result, didn't realize he was speaking it until that morning.

What was really odd though, and here Usopp's ponderings made his brain hurt, was that back in his world there was a place called England as well. It was only a small group of islands, trade routes, were he came from, but still the similarities between worlds were amazing.

As soon as Usopp and the others reached the classroom they all found seats near the front, as, for some reason, Harry and Ron both seemed to be particularly excited about Moody's class. After about a minute, Usopp noticed a distinct cluncking sound coming from the hallway. He took a deep breath. I hope this Mad-Eye person isn't too scary. Then, the man himself came in. Usopp tried hard not to gasp aloud; the man was terrifying. He had grizzled hair and what sounded like a wooden foot, but he also had, and here Usopp couldn't help shuddering, one very strange eyeball. One that seemed to swivel about in the man's head and landed on each person he called on in roll, even though his normal eye never moved from the roll-call sheet.

Usopp was so distracted by the sight of the man that he barely noticed when class started. He tuned in, however, when the words "illegal curses" were mentioned.

"…Do any of you know which curses are most heavily punished by wizarding law?"

Ron raised his hand and answered with something that seemed to be called the "Imperius Curse." With fascination in his eyes, Usopp watched as the teacher took out a large spider from a jar in his desk and proceeded to place it upon his hand. Then the man shouted "Imperio!" Usopp's desk screeched in protest as he pushed it back as far as he could. The spider was performing backflips and cartwheeling as if it belonged to a circus. The whole class seemed to find the dancing spider funny, everyone was in a fit of giggles and laughter. Usopp had a feeling he would have been laughing too, if not for the utter bizarreness of it all. Also, something about the whole act was beginning to remind Usopp of Miss Goldenweek. Only this man can do more than control emotions. Luffy wouldn't stand a chance against this curse. For that matter, neither would I.

The rest of the class eventually came to the same conclusion as Usopp when the teacheras much as told them that it could happen to any one of them. The rest of the class, besides Hermione, looked to be hesitant to answer the question of what the next illegal dark curse was, so it came as a surprise when a boy with so shy a countenance, Neville it seemed, raised his hand.

"There's one—the Cruciatus Curse." The boy's voice had gone quiet when he answered.

Usopp gulped. There's a worse spell than a curse that controls people? Even the name of it sounds horrible. He was right. Professor Moody then took out another spider. Only this one he enlarged, so that all could see the effects of the curse. Then he activated it.

If Usopp hadn't seen pain before, hadn't seen people being sliced to bits and his own nakama, or former nakama, being so hurt they could barely move, he knew he might have run right then and there. The spider was in obvious pain. It was twitching and jerking and was starting to shudder…

"Stop it!" Hermione had had enough. She was gazing with a shocked and sickened expression back at the Neville boy, who looked as though he could faint or puke at any given moment. Usopp didn't blame him, he himself felt almost the same way. This world seems to have a tough love policy when it comes to teaching. Though, personally, I didn't think that old Headmaster would allow this sort of thing. Are all the other teachers like this as well?

The last, and final, curse was the worst one of the three. Hermione suggested it, though even she didn't look happy about saying it. The name, "Avada Kedavra," made everyone in the class uneasy. Usopp bit back the freezing terror rising in him and watched as the professor took out the last spider. A sudden flash of bright green light and it was over. The spider lay on its back, completely dead.

The rest of the lesson was a blur. Usopp had seen Devil Fruits and their terrifying power, had seen massive sea-giants and even real giants, but he hadn't ever seen something that could kill so fast and so easily. By the time he was done reflecting it was the end of class and Hermione was tugging on the sleeve of his robes to get him moving. Ron was gushing excitement. He was talking a mile an hour about the lesson and how "cool" it was. Hermione and Harry were quiter, in fact, Harry actually looked ashen. Usopp wondered if perhaps Harry had never seen death before, but there seemed to be more to it than that. Hermione was glancing worriedly between Harry and the Neville boy, looking as if she wanted to comfort them both, but not entirely sure how. She decided to speak to Neville first.

"Neville?"

"Oh hello," the boy's voice seemed to have gone up a few octaves, landing in a high, squeaky rangeUsopp was sure it wasn't really supposed to reach, "Interesting lesson, wasn't it? I wonder what's for dinner, I'm—I'm starving aren't you?"

Before anyone could ask if the boy was alright, though he obviously wasn't, they heard the clunking footsteps of their professor approaching. The teacher, in an odd act of kindness (in Usopp's mind anyway), asked for the Neville boy to come with him. Harry and the others looked as if they thought that it was a bad idea, Usopp heartily agreed, but they couldn't do anything and so had to walk back to the common room on their own, leaving the poor Neville boy to an uncertain fate.

Before the group reached the common room, Usopp knew he had to ask something, but he felt he would need to ask Hermione alone. "Uh, Hermione? Can I talk to you for a minute, over there?"

Hermione looked surprised for a moment, but nodded. "Sure."

Usopp knew this wasn't going to be an easy question. "Err…Hermione, I know this may be wrong to ask, but why did Harry and Neville react so badly to those curses? They were awful, but most everyone else thought the class was exciting…" He trailed off.

Hermione just shook her head, "I can't tell you about Neville, that secret is his to divulge. But, as for Harry...Most everyone knows about it anyway. His parents died by the Avada Kedavra curse. They were quite famous, and, as you heard the professor say, Harry's the only one that's ever survived the killing curse."

Usopp's eyes widened. This world may be even more dangrous than mine is.

Author's Note: I know, I know; a lot of people wanted Usopp to attend Snape's class… But, I'll get to that later. This chapter is sort of important so I couldn't fit Snape in just yet. Anywho, feel free to review or critique. Thank you for being patient and for reading. :)
