Hogwarts Castle, 2:30pm

The students were uncharacteristically quiet and quick as they took their seats in the DADA classroom. Probably thanks to the new professor's scary aura. Some were excited (like Harry), others quite fearful (like Ron and Neville). Though no one could really tell about Malfoy, was he just putting up a front or just really that confident (or, as Harry put it, just plain stupid)?

All attention snapped to the front of the room as the professor's door opened up. Professor Emiya stood before them, arms behind his back. He took a look around and closed his eyes setting into a slow pace around the front of the room. "How many of you knew that there are three types of 'werewolves' before I told you just now?" Came the first question.

He paused and opened his eyes to scan the room.

"You, Miss..?" He said, seeing only one hand raised.

"Granger, professor. Hermione Granger."

"Yes, , care to give a brief description to the rest of the class?"

Not even giving any form of affirmation, " Type 1 is the one everyone thinks of when the term 'werewolf' is heard. Typically referred to as a 'lycanthrope' amongst other werewolf cultures in order to differentiate. This where the term lycanthropy comes from. They transform every full moon and loose control of their minds. Contrary to popular belief, silver has no effect on them. It can, however, be used to treat the wounds one receives.

"Type 2 is different from type 1 in that they have control over both mind and transformation. They typically get stronger as the moon gets full. They prefer to keep to themselves due to the persecution bought on by lycanthrope's misbehavior, avoiding humans at all times.

"Type 3 is very similar to type 2. The key differences being they aren't as reclusive and take the form of jaguars instead."

'Informed and straight to business. I might end up liking this one.' "Correct"

He continued, "The lack of other volunteers makes the point I was trying to get across. You all, with the exception of it seems, lack information. This deficiency creates vulnerabilities. Vulnerabilities that can be exploited by hostile parties. Based on the notes I have from previous professors, it would seem your education is severely limited. I intend to correct this mistake. We will cover things you may not have heard of. You will be instructed on alternative options to direct combat when faced with these things. There are many ways to neutralize a threat that don't involve overwhelming force... We'll get into all that later however, first things first..." He stopped pacing, opened his eyes and grinned, " How many of you know the differences between Mages and Wizards?"

...

'As expected.' "Who I am?"

Again, a single hand went up.

'Hn, I was expecting the more politically connected students... I'll definitely keep an eye on this one.' " Yes?"

She gulped and felt a bit of regret for raising her hand (not that she'd ever admit it, it was her thing after all). After a little bit of hesitation, " Mr. Kiritsugu Emiya, mercenary-mage who specializes in taking down rogue magical elements, including people. Quite infamous for the ruthless means in which you pursue your targets, earning the moniker 'The Mage-Killer'."

A silence fell over the room. Each student was lost in their own thoughts.

Ron, as per usual, was scared. This fear, however, was different from the typical sharp spike. It was a dull fear, gradually building up.

Harry initially had fear, it was only natural after all. It almost immediately was sedated by the eagerness to learn from this man. One infamous enough to earn a nickname like that surely had to have a lot to teach. Plus, he'd been right about the mercenary thing, score! By the end of his thoughts, he was grinning like an idiot and had a slight sparkle in his eyes.

Hermione held cautious thoughts. Quickly making a list of people most likely to piss this man off. Then thinking through ways to diffuse the situations as they came up.

Malfoy simply snorted and looked away. 'He exists? It was simply supposed to be a ghost story. One father would tell me when misbehaving.'

Finally having had his fun, Kiritsugu broke the silence, "The looks on your faces indicates A healthy degree of caution. Your fear, however, is illogical. Seeing as I am currently under contract to instruct you, it would bring me no benefit to allow harm to come your way."

"Now then, I think our first lesson shall be the same as the rest of the classes. That being the key differences between Mages and Wizards. This way, you'll be able differentiate between the two in an encounter. There by being capable of proceeding accordingly and increasing you chances of survival, understood?"

A round of nods.

" Good. Most of the major differences center around one thing: the way the magic user manipulates and controls their magical energy, or mana as Mages call it. As a mage, I have no need for a wand or similar focus object. This can be attributed to a mage's magic circuits. They act as an extra organ, allowing one to gather, control, and manipulate mana internally. One drawback is the limited storage of mana allowed per circuit. They are similar to muscle tissue, use and exercise them and they improve, neglect them and they deteriorate. Allow me to demonstrate the wandless control."

He then stuck out his right fist and grabbed his wrist with his left hand. Concentrating on his hand, he activated his circuits. The students got really interested when the light green maze work glow showed up on his arms before moving to the palm of his right hand. Then he let go of his wrist, turned his fist over and opened it slowly. As he opened it, a small fire could be seen. That wowed most of the students. He left it open for a few seconds, allowing every student to get a look before closing his hand again. " This was a simple elemental affinity demonstration. Used mostly to determine which kinds of magic one would be best suited to study. Moving on."

"Wizards, on the other hand, have a nearly unlimited mana storage that seems to be stagnant,neither improving or deteriorating. This creates the draw back of needing a magically resonant object with which to use that massive mana pool. Take it away and they have no magic."

"How exactly Wizards process and store mana remains a mystery to even the brightest minds in the magical community. Theories have been tossed out here and there. Ranging from magic cores, similar to a phantasmal beast, to using the unused DNA in each human cell. I'm not really sure myself, nor do I really care. All that matters is that it makes you more vulnerable if someone can remove your wand from you. A vulnerability I intend on bypassing by teaching you other methods of neutralizing a hostile opponent."

Just as he finished, another student burst into the room. He looked like he'd been running and had a stack of papers on him. "Sorry I'm late professor, took longer than I thought to make these up," he panted out, clearly out of breath. Odd, he looked like a seventh year.

"I'll let it slide, just hand them out."

"Yes sir."

"Class, this is Henry Knightly. Hell be helping me teach you seeing as I've just explained our magic is incompatible. He will take care of the defensive spells that I can't teach. The paper hes handing out is an affinity test. I believe I explained affinities earlier. The results could help you in other areas of study as well."

Harry's first impression of this year hadn't been the best. What, with the hippogriff attacking Malfoy(although he didn't feel as bad as if it was someone else), and then the stuff in divination. This class, however, had him thinking, 'This year's going to be great!'

:::::-:::::

AN: Well, there it is! The first class with Kerry. Was a little harder to write than I thought it'd be. Real life was no help either. Anyways, someone said Harry and Iri? Well, I got kinda interested in the concept and started planning it out. If I end up putting it in, I'll try to adhere to psychology and real life as possible. Instead of rushing it, making it feel forced. However, I will add fluff if I get enough requests about it... That's if I even put it in in the first place.

UNTIL NEXT TIME! give your opinions, Harry and Iri? Yay? Nay? Go? No-Go?
