A/N: I finally have the next chapter done. Sorry about the wait but I had to study for my exams and then I had to do the actual exams. I'm sorry /(_ _)\
Anyway lets go onto the chapter.

Disclaimer: I do not own KHR or Harry Potter, they belong to Akira Amano and J.K. Rowling respectively.

Warnings: Probable OOC-ness, Boss!Tsuna and cursing( mostly Gokudera but too much exposure causes other characters to pick up the habit.)

Tsuna didn't find it surprising when nearly all the students raised their hands. He wondered how many of them knew how to properly throw a punch, but he would think about that more later.

"Ok then. Has anyone ever been hit before?" Muttering among the students began. Tsuna noticed that the Gryffindors all looked over at the blonde and then would turn away smothering laughter.

"How about you? Have you been hit before?" Tsuna pointed at the blonde. He watched as the blonde went slightly red in the face. The rest of the students were unable to smother their laughter after that.

"Malfoy got punched in the face by Hermione during our third year." A red haired student gasped out between laughter. That just made the students laugh even harder. Tsuna smirked slightly and saw that some of his guardians had done the same. Who could have thought that that girl could have punched someone, but looks can be deceiving.

The blonde looked murderous. As the students were laughing he pulled out his wand. Tsuna's eyes trained onto the movement instantly. He appeared behind the student and pulled the wand out from his hands before he could even move his mouth. The blonde trained his glare onto Tsuna, but then looked in shock at the sight before him.

Tsuna had pulled up his dying will and gone into Hyper Dying Will mode. His orange eyes burning into the blondes, his flame flickering on forehead. The other students looked on in shock. None of them had even seen the boy move.

"Rule number one of this class: No magic is permitted. If you do it will result in the confiscation of your wand, which you will have to get from Dumbledore's office. Do you understand me?" The students all nodded quickly.

"Good. Now then, how about we continue with this lesson." Tsuna gave the blonde back his wand and left Hyper Dying Will mode, then walked back over to his guardians.

"So we have found out that most of you know how to throw a punch, but do you throw them properly?"

*Hedwig*

Harry was enjoying the lesson so far. Malfoy had been humiliated three times already and the class had only just started. He could see that Tsuna-Sensei felt that Malfoy was a pain. It was surprising when he plucked Malfoy's wand from his hand before he had even said anything. Nobody had even seen him move.

What had been more surprising was the flame that had appeared on his head. Harry was confused and wondering how it worked. Maybe he had a fire protection potion, but it didn't explain why it was on his forehead of all places.

"So what do you think about Tsuna-Sensei?" Hermione asked them.

"I like him so far. He seems cool." Ron replied. Harry nodded in agreement.

"Yes, I agree too. But I think he is hiding something." Hermione mused.

"When don't we have a teacher that isn't hiding anything?" Harry asked her. Hermione was about to reply when Tsuna-Sensei called the person with the cropped white hair. Harry thought back to the introductions and realised that he was Sasagawa Ryohei.

"Alright, looks like I extremely get to show you al how to extremely punch correctly." He shouted at the students. Harry saw Tsuna-Sensei shake his head slightly and sigh.

"Onii-san, why don't you lower your voice a little please?"

"Of course Sawada. Now then, can you all stand in a line and we will go around and pair you all up." The students hastily moved to do as he had told. Harry tried to get as far away from Malfoy as he could. The teachers went around and paired different people together. Different houses were mixed, and so were genders. Harry watched Tsuna-Sensei closely as he walked towards him.

"You can be with him over there." Harry looked over at where he pointed and saw that he was supposed to be with Malfoy. Before Harry could ask to go with someone else, Malfoy piped up.

"What!? You expect me to be paired with Potter? That won't be happening!" Malfoy was then receiving a glare from the silver head.

"Oi, Jyuudiame has decided that you will be paired with him, so you will listen to him." Harry watched as Malfoy then proceeded to have a heated argument with the silver head. He remembered what Tsuna-Sensei had said about him when he was introduced; that Gokudera Hayato had a fiery temper. Harry could clearly see that now.

"I will not stand for being paired with Potter." Malfoy looked disgusted as he spat out Harry's name. He was about to interject, when Malfoy continued.

"You're probably a Mudblood as well." Every person fell quiet at that remark. Gokudera looked confused until the man in the suit whispered something into his ear. Once the man stood back, Gokudera's face had exploded with rage.

"Hayato, ignore him." Tsuna-Sensei turned to Gokudera. He immediately turned and walked to a door in the back that Harry hadn't seen until he walked through. The door slammed shut behind him and when Harry looked back at Malfoy, he saw that he had a smug look on his face.

"You know, it wasn't nice to call him that you know." Harry quickly thought back to the introductions and remembered him as Yamamoto Takeshi.

"What do I care? You're probably one as well." Malfoy kept running his mouth. Harry felt his jaw drop. He was going to continue insulting each of the new teachers. Was he insane?

"Herbivore, shut up before I bite you to death." Harry's head snapped towards the menacing aura emanating from man with the messy black hair. He was holding a pair metal poles in his hand that Harry thought looked like the batons that cops used.

"Kyoya, put your tonfas away. You're scaring the other students too." The man just shrugged and lent back against the wall. Harry shuddered and made a mental note to stay away from him.

"I would say that all of you are Mudbloods. Am I right?" Malfoy was really beginning to get on Harry's nerves. There was a loud slam and all the students glanced at the door and saw that Gokudera had come back into the room.

"I extremely suggest that you stop insulting my family." Harry looked at Sasagawa.

"Are you insulting my dear Chrome?" Now the pineapple head was getting involved. Chrome was standing behind him, but she was glaring at Malfoy as well. Harry looked around and saw that nearly everyone was involved in the fight, the students were just watching on in amazement.

"Tsuna-nii, what is a Mudblood?" Harry looked over at Tsuna-Sensei and saw that the boy was standing next to him. Tsuna-Sensei bent down slightly and picked up the boy.

"Well Lambo, a Mudblood is a very bad word that is used to insult people who are born to muggles or don't have 'pure blood'." Harry watched as Tsuna-Sensei carried Lambo over to a chair.

"So I am right? You are all Mudbloods born from filthy muggles?" Malfoy just didn't know when to quit. Harry noticed that all of the teachers had stilled at his words. Tsuna-Sensei, with Lambo in his arms, and the man in the suit both turned towards him.

"What did you just say?" Tsuna-Sensei hissed out from his teeth.

"I said that you are born from filthy muggles." Malfoy was just digging his grave deeper. Harry noticed that Lambo was struggling out of Tsuna-Sensei's arms. Tsuna-Sensei himself didn't realise until Lambo was standing in front of Malfoy.

"Lambo what –" Tsuna-Sensei had started towards him when the man pulled him back.

"Don't insult Mama." Lambo shouted at Malfoy. Malfoy looked down at the boy in disgust. Harry wanted to pull the boy back to safety. He looked over and saw that Hermione wanted to do the same thing. Actually it looked like lots of the students wanted to.

"What are you going to do about it? Cry?" Malfoy sneered down at the boy. Lambo's eyes started to tear up but then the air around him started to crackle with electricity. Malfoy took a step backwards, startled. Lambo glared up at him and the electricity around him became more concentrated.

"Don't insult Mama." He yelled again. Glaring at Malfoy he adjusted his horns slightly.

"Thunder set." As he spoke the electricity, which had started sparking outwards, gathered in his horns. Malfoy took another step backwards getting scared again. Harry took a quick glance over at Tsuna-Sensei and saw that he was struggling against the man holding him.

"Lambo don't do it." He cried out, but Lambo didn't turn around. The electricity surrounding him was crackling more fiercely.

"Elettrico Cornata." The electricity that had gathered in his horns then began sparking and Lambo ran at Malfoy. Malfoy was too shocked to move and Lambo's horns connected with his legs. Lambo watched, pleased with himself, as Malfoy fell to the ground twitching.

"I told you not to insult Mama." He said as he walked over to where Tsuna-Sensei was standing.

"Tsuna-nii, Lambo-sama is tired." Lambo reached Tsuna-Sensei and then climbed onto the table near him and promptly fell asleep.

All the students watched as Malfoy continued to twitch occasionally.

"Reborn, you can let go of me now. I need to check and make sure he is fine." The man let go of him and he walked over to where Malfoy was lying.

"Can you tell me your name?" he asked and the students watched as Malfoy opened his eyes slightly.

"My name is Draco Malfoy." He replied, his voice scratchy.

"Can you tell me where you are?"

"I'm at Hogwarts." Tsuna-Sensei nodded.

"Onii-san, can you get over here please?" he called behind him. Sasagawa walked over.

"Yes, Sawada? Would you like me to help him?" Tsuna-Sensei nodded and then stood up. Sasagawa instantly took his spot.

Tsuna-Sensei sighed and then turned to face the students.

"Well, I guess that we will have to cut this class short today. Class is dismissed. Hopefully there won't be a repeat of this next lesson." At his words all the students began to move out of the classroom, giving a wide berth to the Malfoy. Harry glanced behind him as he left and he saw that Tsuna-Sensei was watching the students leave. When he caught his eye, he smiled and Harry quickly looked away and followed Ron to the Gryffindor Common Room.

"That was an interesting lesson." Ron said as they walked.

"You can say that again." Harry replied. He personally wanted Malfoy to suffer during the next lesson too.
