"Jyuudiame, there is a letter from the pink toad here for you." Gokudera walked into Tsuna's office with the letter in his hand. Tsuna looked up from the stack of paperwork he had been signing before dropping his pen and flexing his wrist.

"What is it about?" Tsuna asked, stifling a yawn. It was nearing 3 o'clock in the morning and he had yet to finish the paperwork before him.

"It appears that the toad will be sitting in on our lesson with the fifth years. She apparently will be seeing whether or not we are good enough to teach at this school." Gokudera folded up the letter and placed it onto the desk beside the half empty coffee mug.

Tsuna sighed and placed his head on the desk, but then quickly moved off it and rushed out of the room. Gokudera looked after him startled, before following him out. Tsuna moved quickly and had slid a note underneath both Mukuro's and Hibari's doors, before making his way towards the kitchen area. Gokudera was still standing in the doorway of Tsuna's office and watched as a few minute after Tsuna walked back out of the kitchen with tea and coffee in hand, Mukuro and Hibari both exited their rooms.

Now this was a disaster waiting to happen. Thankfully Chrome followed Mukuro out so an all-out brawl didn't happen right then and there, but a glaring match did occur. They each settled at separate ends of the couch, with Chrome in between them, and waited for Tsuna to speak.

"I need you two to make sure that you are on your best, best, behaviour for the next few days. Also Chrome, I would like you to find out exactly what Professor Umbridge would like to see from the class. She isn't coming until the fifth year lesson, but I would like to be prepared." Tsuna ordered his guardians in front of him, emphasising the seriousness with his Will when it looked like Hibari and Mukuro were going to argue. Chrome nodded her head and immediately left the room to go to sleep so she could get an early start to following Umbridge around. Hibari and Mukuro shared a final glare before picking up the tea and walking back to their rooms. Tsuna sighed before picking up the coffee and walking back to his office.

"I have a bad feeling about this Hayato." Tsuna had stopped in his doorway and was watching as the coffee, which had been on his desk, dripped onto the floor.

"A very bad feeling."

"I am here to teach you using a Ministry-approved method that does not include inviting students to give their opinions on matter about which they understand very little. Your previous teachers in this subject may have allowed more licence, but as none of them – with the exception of Professor Quirrell, who did appear to have restricted himself to age-appropriate subjects – would have passed a Ministry inspection –"

"Yeah, Quirrell was a great teacher," Harry said loudly, interrupting Umbridge in the middle of her rant, "there was just the minor drawback of him having Lord Voldemort sticking out of the back of his head."

This pronouncement was followed by one of the loudest silences that Chrome had ever heard. Then-

"I think another week's detention would do you some good, Mr Potter," Umbridge said sleekly.

Chrome sighed silently as she watched the proceedings of the class. The class had only just started and Harry had already landed himself in detention with Umbridge. She let out another sigh before glancing around. No one in the class had noticed her, but that was to be expected. She had been following Umbridge around the whole day and hadn't been noticed. There were a few times that she had been sure she would get noticed, but it never happened.

Grimacing slightly, she looked down at the clip board she had in her hand. She had created a copy of Umbridge's notes on the other teachers. It had been a little challenging, but as all she had to do was read it, she was able to create an exact replica. With one last glance around the classroom, she silently made her way out. There was nothing more to be gathered, and it was high time she returned before Mukuro and Hibari went against their orders.

She quickly made her way up to the seventh floor and opened the door slowly. The class before her was watching in horror as Mukuro and Hibari were having a battle so intense that no one could get close to them. The other guardians were watching in undisguised horror and were crowded around a figure that was lying on the ground. Chrome let out a small sigh before looking more closely at the figure on the ground. She drew in a sharp breath when she recognised the brown haired figure lying there. Chrome turned back to the pair that was fighting.

"What the hell are you two doing, you fucking idiots?" Chrome's shout made every head turn towards the door. She had forgotten that she was still invisible when she had walked in, and therefore was a little surprised at the faces the class was pulling but that thought was quickly pushed to the back of her mind.

"Boss told you that you had to be on your best behaviour. Is this your best behaviour?" She asked them, mainly Mukuro, as she walked towards them. Chrome had unconsciously slipped into Japanese because of her anger towards them, and was starting to become visible to everyone.

"You two just couldn't help yourselves and now Boss is unconscious on the floor. Not only did you disobey him, you knocked him out!" Chrome immediately assumed that they were responsible for Tsuna being unconscious on the floor, and ignored the way that Mukuro was trying to defend himself saying that they didn't do it.

"Stop talking. You are coming with me and will be doing some paperwork until Boss is awake again and you will be apologising for this." With those words Chrome grabbed Mukuro's collar and gave a glare to Hibari, who followed as she dragged Mukuro into the offices.

The dining hall was filled with a lot of chatter coming from the sixth years at dinner time. A lot of them were glancing at the table that Tsuna and his family sat at. Harry glanced over at it too and saw that Tsuna, Chrome, Mukuro and Hibari were missing. He shrugged before turning back towards his food.

"Well now we understand why Chrome can stay in that family full of males." Fred said as he sat down at the table.

"True that," George commented as he sat down.

"Why's that?" Ron asked before taking a bite out of a chicken wing. Fred and George exchanged looks before gesturing towards the table where the other sixth years kept glancing.

"Hibari and Mukuro started a massive fight in class when Tsuna-sensei had collapsed suddenly and then, after it had been going on for a few minutes, a massive shout echoed through the room. The minute it happened, the two stopped fighting. We had no idea what had been said though, I think it was in Japanese, and Chrome was walking through the classroom towards them, looking so angry." Fred explained to them.

"She's the reason they aren't here at the moment. They have to do some paperwork or something for Tsuna until he wakes up and then apologise to him. Given that they aren't here means that Tsuna hasn't woken up yet," George told them before picking up some chicken and placing it on his plate.

"How do you know that? I thought you said that she was speaking in Japanese?" Hermione questioned.

"After she dragged them into their office, Reborn appeared and explained what she said." As soon as Fred finished speaking, the doors opened and the missing teachers ambled into the hall. Chrome was blushing furiously and was apologising to Mukuro about jumping to the wrong conclusion about something. Once they had passed, Harry looked at Fred and George.

"She thought they were responsible for Tsuna being unconscious, didn't she?" He asked the twins.

"Yep," The twins replied, nodding their heads. Harry nodded back before standing up.

"Well, I'll see you guys later. I don't want to give Umbridge an excuse to give me any more detentions." They all muttered goodbyes and Harry walked away, ready to cut open his hand again.

Tsuna was still flicking through the report Chrome had given him when the fifth years ambled into the classroom. He looked up briefly to see if Umbridge had arrived yet, but then looked back when he saw that she hadn't. The students had all sat down and were waiting for him to start the class, but he just sat there, reading the report.

For the lesson today he had confiscated the weapons from his guardians and was planning to show the class what they were and teach them about defending themselves from different weapons, as well as some basic skills at dodging. Tsuna glanced over at where Reborn was standing, polishing his gun before placing it on the table with the other weapons.

When Tsuna had been told what had happened after he had collapsed from lack of sleep, he had been very disappointed in his guardians. It was only because of Chrome's arrival that the classroom didn't get destroyed. He had ordered Hibari and Mukuro to stay in their rooms (he felt like a parent when he said this) and they were not allowed to come out once during the fifth year class. They could only come out if it was a dire emergency that they couldn't fix themselves. Chrome was staying with them to make sure that they obeyed him this time and his other guardians were in their offices as well. Reborn was out here with him because he felt that he would most likely need Reborn with Umbridge in the room.

"Alright, today, as you can most likely guess, we will be learning about the different weapons that muggles can use when they fight." Tsuna said, placing the report onto the table and looking at the students. Before Tsuna could speak again the door to the classroom opened and Umbridge walked in.

"Ah, hello Professor, pleased to see that you could join us. There is a seat over there that you can use." Tsuna smiled at Umbridge and gestured at a spare seat near the students. He could hear a slight chuckle coming from a few of the students when he had spoken and his smile became slightly wider. It appeared that some of them had head the hidden meaning behind his words.

"Now then, as I was saying," Tsuna continued once Umbridge was seated, "muggles can use many different weapons when they fight. There are some that dedicate their lives to a certain weapon and will spend their life training with it." The class was drinking in his words with some excitement and Umbridge was scratching away at her clipboard.

"These weapons on the table are some of the ones that I and my family use." He said gesturing to the table. A hand shot up into the air when he said that. Tsuna looked slightly amused at that, but wasn't the least bit surprised to see that it was Hermione's hand that was raised.

"Professor, why do you and your family use weapons if you have magic?" She asked when Tsuna had nodded at her.

"Well, Miss Granger, as you all know, my family's magic is different to yours and as such they have different properties. Depending on the 'flame' you have, you have different abilities. You are all able to fight, heal, and defend using your magic, whereas we cannot. Taking our flame's abilities into consideration, we must find a weapon that will either increase its offensive or defensive abilities. Certain flames are able to heal, so each family makes sure to have at least one person with that ability." Tsuna stopped talking when he realised what he had said. He had just given away some information that they had said they weren't going to. He could feel Reborn's eyes glaring holes into the back of his head.

"Anyway, we must choose a weapon, much like how you have wands, that allows us to use our flames to the best of our ability." He finished before turning back to the table beside him.

"Each weapon here is a reflection of both personal taste and need for the flames that we have. However there are ordinary muggles who will use these weapons as well." Tsuna picked up Reborn's gun from the table, ignoring the possessive look that appeared on the ex-arcobaleno's face as he did.

"This is, as most of you will know, a gun. It shoot's both ordinary bullets and, because it has been modified for Reborn, special bullets to increase his flame's offensive abilities." He handed the gun over to Reborn, who took it back and immediately set about polishing it again. Tsuna then gestured towards the target that was leaning up against the wall. At his gesture the students, and Umbridge, all turned to watch as Reborn shot the target five times in the centre using ordinary bullets.

The students looked awestruck and started clapping as Reborn stepped back behind the table. Tsuna sighed lightly. Reborn's skill with the gun is amazing, but when it is used against you it is terrifying. He shook his head to get rid of those thoughts and then moved back to the table. After a moment's hesitation he picked up Hibari's tonfas, half expecting the skylark to come bursting into the room. It didn't happen though, so he twirled them around before starting to talk.

"These are tonfas. They are not very well known weapons, but when used correctly can hurt quite a lot. Kyoya used these at our school to beat up anyone who disobeyed the school rules or disrupted the peace. These had been modified and had hidden compartments in them before he even found out about the flames. When he did, they were modified again to –"

"Omnivore, what are you doing?" Tsuna jumped and spun around to find Hibari leaning against the wall. Hibari smirked and pushed off from the wall, making his way towards Tsuna.

"I could ask you the same thing, Kyoya." Tsuna glared after he got over his surprise. When Hibari was standing in front of him, the skylark held out his hands. Tsuna immediately knew what he wanted and shook his head.

"You are being punished for your behaviour yesterday, Kyoya. You will not be getting these back until tomorrow." As he said that he pulled out a sky storage box that Spanner and Shoichi had made for him and put the tonfas inside. The look Hibari gave him as he did that almost made him take a step back in fear. Instead he brought up his Will and looked him in the eye.

"Now then, Kyoya, I think it's time that you went back to your office to finish off the paperwork that you have to do," Tsuna's eyes blazed with the promise of a longer sentence without his tonfas if the skylark disobeyed him. Hibari glared but then turned away and stalked back into the office. After the door slammed shut, Tsuna let out the breath he had been holding. There was a faint echoing and Tsuna realised that the whole class had been holding their breath as well.

"Now then the next weapon I will be showing you is –" The door slamming open again cut off Tsuna's words.

"Gyahahaha, Lambo-sama has escaped from the clutches of the evil Octopus-Head Stupidera."

"Stupid Cow, get back here and stop bothering Jyuudiame."

Lambo came bursting into the room and was followed by Gokudera's shout. The class jumped at the sudden appearance of Lambo and they all watched as he ran over to Tsuna.

"Tsuunnaa, play with me." The child whined.

"Not now Lambo. As you can see I am in the middle of teaching the fifth years. How about you go and play with Takeshi?" Tsuna offered before pushing him back towards the door.

"But he's busy doing other things," Lambo complained over his shoulder at Tsuna, digging his heels in the ground so he wouldn't move. As he said that Gokudera and Yamamoto walked into the room.

"Stupid Cow, stop annoying Jyuudiame." Gokudera thumped him on the back of the head, ignoring the brief shout of outrage that came from the students. Yamamoto was just standing beside him laughing. Tsuna just sighed before motioning for them to move out of the way.

"Okay so, the next weapon that I will be showing you is this bamboo sword called the Shigure Kintoki. It is used by Takeshi, but it is not just an ordinary bamboo sword." At Tsuna's words, Yamamoto picked up the bamboo sword and flicked it. A gasp of surprise echoed around the room as the students all stared at the now metallic sword.

"Normal swords are usually already found made of metal and, much like knives, they will cut you if you use them wrong. Swords are one of the weapons that certain people will dedicate their lives to. Obviously Takeshi's is different, but most swords are very similar to what it looks like now." Tsuna finished before having Yamamoto change the sword back to its bamboo state. Once that was done Yamamoto grabbed Gokudera, who had a hold of Lambo, and dragged him over to the doorway they had burst through earlier.

Tsuna let out a sigh before looking down at the weapons again. Just as he reached out to grab the next weapon another shout echoed out of the office.

"Mukuro-sama, get back here!" Tsuna groaned and stepped to the side just in time to watch Mukuro fly past him. The students all watched in amusement as Mukuro got up off of the floor and tried to launch himself at Tsuna again. This continued for a few seconds until footsteps were heard getting closer. As this happened, Mukuro froze before diving behind the students.

"Hiding within the students will not to anything Mukuro. She will drag you back into your office whether you like it or not." Tsuna told him, shaking his head.

"But Tsunayoshi, I have been in there for the whole day doing nothing but signing paper after paper. I need a break." Mukuro replied, not coming out from his hiding spot.

Tsuna twitched at his words and felt his anger, which he had been keeping to a down low this whole lesson, rise and nearing its breaking point. He took a deep breath to try and calm himself down. Tsuna noticed Reborn glancing at him, but he ignored it and continued focusing on his breathing.

He noticed when Lambo came running back into the classroom followed by a screaming Gokudera and a laughing Yamamoto. Tsuna noticed when Ryohei walked into see what all the screaming was about, joining in in the process. He also noticed when Chrome walked out with a deathly glare fixed onto Mukuro who was still among the students. Throughout all this he just focus on keeping calm and not letting his anger boil over.

He ignored the shouting match that erupted between Gokudera and Ryohei. He ignored Chrome dragging Mukuro out of the students by his collar. He ignored Lambo's whining and Yamamoto's laughter. Tsuna just kept taking a deep breaths. Finally he opened his eyes, he didn't remember when he had closed them, and looked over at them. He had managed to rein in his anger for now and hopefully he would be able to continue the lesson without any more interruptions.

But alas, as soon as he thought that Hibari stormed into the room with a spare pair of tonfas in his hands. As soon as he spotted Mukuro, the fight they had started yesterday was continued. A few seconds later a loud snap echoed throughout the room.

That was when all hell broke loose.

A/N: Oooh the cliffie. My guess is a few of you will know what snapped. Anyway, hope you enjoyed this chapter. Leave a review and let me now what you tink is happening/going to happen, some suggestions, constructive criticsm, spelling and gramatical errors, and the like. Please and Thank you.
