I don't own Harry Potter in any format, this is a fanfiction only.
AN: Edited due to protest of depicting sexual theme involving a pair of minors, never mind that they are actually legally married and Harry has killed and devoured an adult hit wizard.
The next day Harry was up and kissed his mate in the way of humans, something that Fleur was very happy to receive. As the two got dressed she noticed that he was not getting dressed in his student attire. She could not help but feel proud that her husband managed to do something most consider impossible.
He got dressed in his normal combat attire and was getting ready to go down for breakfast, till he saw Fleur and currently she was not wearing anything except a pair of red silk panties. Harry knew that he should remind her that they would be late, but the sight of his wife was causing a conflict of interests. On the one side he certainly enjoyed how comfortable she was with him to be able to look at her like that, and on the other, he really needed to get to eat breakfast, it was the first day he was to teach a class.
"Fleur, we really need to eat breakfast and I might need your help with something." She looked at him and smiled as she used her magic to finish getting dressed. She walked over to him and looked at him with a smile on her face.
"I know you will do just fine teaching that class, my love. There is nothing for you to worry about. The only problem is that the only breakfast I wanted was you, but I guess you are right. We really can't be late for class. It's your first-day teaching, and we don't want to set a bad example for your students now do we?"
They ate breakfast and sure enough, there was someone to remind Harry that he was supposed to eat his meals on the staff table. He looked at the Headboy and glared at him. "As a teacher, I eat where I choose, and I choose to eat with my beloved. Now, do you mind I have a busy day ahead, and I might not be able to see my beloved wife till lunch."
Fleur kissed him on the cheek and wished him to have a fun day teaching his classes.
Harry walked into the classroom and began to write down on the blackboard, as soon as he was finished he waited for his students to show up.
Harry loved the way the supposed older students walked into the classroom expecting to see someone close to the age of their grandparents. He especially loved the way everyone seemed to just talk among themselves thinking the professor was late, Ok the last part was not true. He was angry about it actually.
He stood in front of the class and pretended to clear his throat. When that didn't work he cast a spell that cut an empty desk in half, causing two students to fall down.
He got some angry glares from them, with a quick wand movement the desk was as good as new. "Now that I got you attention, sit down and I mean right now. I am your new professor, I am Harry Potter and I will not accept any foolishness in my class."
"I will teach you the subject often referred to as Dark Arts, but in truth, I will teach all manners of way magic can cause harm to people, animals, and even the environmental around you. The world is not as safe as you would think, and you will need to learn things to defend yourselves and those you care about."
Several students were still ignoring him, "All those that don't take this class seriously will be removed from it, and since this is a core class. You will be promptly told to collect your things and an expulsion notice shall be sent to your parents or legal guardians."
That stop the clowning around faster than Harry could eat a large slab of meat. "Since this is the first day for us, we are going first to answer a brief exam. Those that pass the exam are going to get away with not doing your homework for today."
He flipped the blackboard with a movement of his wand, "These are the question and you have five minutes to answer them." Everyone began to work frantically to answer the question except for two students who did not move at all.
There is always trouble students in every class, Harry knew not to expect otherwise. He told them to collect the tests and two minutes later he had all the exams graded.
"Very well it seems you did not learn the use of the misdirection hex and your knowledge of elemental magic is woefully inadequate. Let's begin with the misdirection hex, and if we have time we will discuss the elements."
With a quick motion, an empty chair became a rather large chicken. He then said a few words and with a few waving movements of his wand, the chicken began to look like it had been drinking some rather heavy alcohol.
"As you can see the chicken, is disoriented but that is not the real effect." He threw a piece of chalk and everyone expected the chicken to jump left, but instead the chicken jumped directly in front of the path of the chalk.
"The dizziness is a temporary side effect, what the spell really does is a mess with the subject's sense of direction. I threw that piece of chalk and the chicken more than likely jumped left to avoid it, but in reality, he actually jumped right and got hit by my piece of chalk because of it."
"Any questions?" Harry looked at his class and one of the students smiled and rose his hand.
"Professor are we going to learn only things useful in combat? We aren't fighting in a war, we are in peace time and there is no reason to be concerned about our safety."
Harry immediately began to glare at the student, "Mr. Cormic there is no such a thing as no reason as to not be concerned about your safety or the safety of those you care about. Yes, in this class you will learn magic specifically used in combat. You need an incentive to learn it, think back to something that happened this month."
The entire class turned pale as Harry told them that, "I devoured a hit wizard that wanted to kill a student at this Academy, and one of your fellow students died. The wizard that killed him used his corpse to make a potion to take his shape and infiltrate this school."
"Had you fellow student heard my words he would have done as I am going to tell you now, you must have constant vigilance, do not take anything for granted. A danger can come from the least likely place. In this class, you will learn to fight as if your life depends on it."
He looked at the student who slowly sat down, "Because as long as we live in these chaotic times, your life is in danger. I will give teach the skills you need to defend yourselves and those you care about."
"Now on to the elements, magic has been divided into different branches since time immemorial, charms, curse, hex, and all another manner of spells. Before this, however, the spells were also divided into elements. Wind, Fire, Water, Earth to start with the basics. They combine in Ice, Magna, Lightning, and such. By the end of this year, you and your classmates will know how the elements can affect your surroundings, to turn a forest into your fortress, to derive victory from a desert and to survive thanks to a storm."
"Today will begin with the Element of Wind, to be more specific how the wind can be used to defend or render an enemy defenseless."
Harry took his wand and without a saying, a word a ring of fire appeared around him. "This is a fire spell called the Inferno Prison, it was invented to limit the movement of an enemy. With the use of a small wind spell also called Wind's breath see what happens."
Harry began to move his wand and sure enough, the fire ring began to die down till it was nothing.
Harry placed the class behind a shield and cast the same Inferno Prison but this time away from himself and the class. "Now see what happens if I use the spell Wind Blast." Again he moved his wand and a large wave of wind began to blow until it hit the Inferno Prison and the Inferno Prison exploded in a massive ball of fire burning everything around it.
"Had a person been inside that ring they would burn till there is nothing but ashes. One wind spell and the difference is between life and death like I said class, constant vigilance."
From that moment on the class was looking at him in a much different way depending on who it was, some students looked at him with awe, some with fear and some others with utter interest.
The class clowns didn't make any attempt to disrupt the class since they knew that Harry was not one to mess with. The class went through the basic elements and the way they affect each other, at the end of the class they knew exactly what to expect from their teacher from now on.
Harry was strict but fair, he always said things clearly and he always meant what he said. The class understood exactly what he meant about when he said turning a forest into a fortress, how one could survive in a desert or even gain victory with a storm.
The class ended and he looked at the classroom, the place had been changed into a more practical place, he had removed the seats and they had practiced what they had learned, as a result the room looked like a small disaster area.
One move of his wand and all damage was repaired, and all the seats were back to their original state. "Professor, what spell is that?" He looked at his student and smiled, "It is nothing major just some household magic. They can be found in any bookstore or this school library. I highly suggest that you avoid the works of one Gilderoy Lockheart. Winner of the most dazzling smile he may be, but that does not make you an able wizard."
He began to prepare for his next class and so his day went on. By the time lunch finally came he had taught three classes and was quite hungry. He walked over to the teacher's table and sat down.
Madame Maxine looked at him with a knowing smile on his face, "Not so easy being a professor now it is Harry? And that was only three classes, you still have three more after lunch. Don't forget that tomorrow on you will have to grade all tests, and assigned work."
Harry looked at her with a smile and nodded his head, "I find that practice time is an adequate time for testing their knowledge. As assigned work, I only assign reading, which will be tested each following day with a prompt two question quiz. The paper I use is enchanted to be both cheat proof and enchanted to check itself with my own copy of the quiz, so the grading is done as they finish the quiz."
Several of the other professors looked at him and then began to nod their heads, "I never thought of doing something like that, it would sure save me some time with grading. I hate the excuses some of my students give me for failing to do their assigned work."
He looked at his plate and saw that it was a rather yummy leg of lamb. He, of course, began to rip pieces of it with his claws, before the headmistress reminded him they had utensils to do that. Harry quickly remembered that he had to eat as a human. He changed forms and began to eat as a human.
"Excuse me, Madame Maxine, it is a simple habit of mine, I find that I can taste my food better when I am in my feline form." The professors began to eat their lunch and he found that he wished he could sit with his beloved mate, but he couldn't. The teachers and students ate in separate tables.
That didn't mean however that he was not able to keep an eye on his mate, and she actually knew it. She would sometimes look up at him and smile.
He finished the remaining classes and soon enough he was in bed with his mate. They had just enjoyed a nice shower together, and let's face it Harry enjoyed immensely being so close with his mate.
They laid there together and she finally asked him a question, "Harry you could have remained a student and been with me the entire day, why did you choose to become a teacher? And why didn't you eat lunch with me or dinner for that matter."
Harry began to touch her hand, "I felt that eating with you was being unfair to the other teachers. I decided not to do something that would eventually cause trouble with my fellow teachers and so I decided to eat as they do. I became a teacher Fleur because I need to earn an income, I think I already told you. I need to earn enough to buy you a nice home, and it has to be big enough for us and the little girls we will have together."
She smiled and kissed him on the cheek, "Very well husband, I shall accept that. I did notice you glaring at the head boy from your seat. I guess you are always keeping an eye on me, trust me, my beloved husband, I would never cheat on you and I know you would do the same for me."
Harry smiled and kissed her too but not on the cheek but on her lips. "I tell my students to have constant vigilance Fleur, I am only doing as I teach and your father has many more enemies that could try to get to him, by hurting you. I trust you, and I hope you forgive me for being so hard on you during your class."
She smiled and placed her head on his chest, "I wouldn't have expected you to give me preferential treatment simply because I was your mate, and so it didn't bother me one bit. In fact, I found the class you taught to be quite interesting in comparison to the way the previous teacher was teaching the class. You are more practical and if I had any trouble was trying to hide how proud I was of you."
